Submersible Pumps

The Complete Guide to Floods

Once called “once in a thousand year” events, flooding in the UK is quickly becoming quite common. While responsibility for what is causing the common occurrence of flooding varies between warmer winters generating higher levels of precipitation and councils not properly considering floodplains when granting planning permission for new builds, the reality in Britain today is that flooding can happen anywhere and at any time of the year.

That’s why almost everyone should have a plan in place for the event of flooding. Flooding can have disastrous consequences for your home, and not being adequately prepared, whether with tools or simple knowledge, can make the consequences all the more dire.

So what should you do in the event of a flood? How can you prevent flood damage? And what are the best tools for cleaning up flood water? Here we list all our advice for flooding along with the essential tools for cleaning up flood damage.

Are you at risk of flooding?

Concerned about the possibility of being at a flood risk? Luckily if you are worried about flooding there are several interactive, government and council alert services that can give you basic information regarding your flood risk.

For immediate flood risk information you can check your location using this government tool here:

For information regarding your county flood risk over the next 5 days you can check another government service here:

For information regarding your general flood risk you can use another government service here:

For an interactive visualisation you can use Shoothill’s service here:

Remember that even if flooding doesn’t directly threaten your location you may still be affected by cuts to transport, power and communication networks. Don’t just check your postcode. Check surrounding postcodes too. Just because your home isn’t directly threatened by floods doesn’t mean that neighbouring homes and streets are unaffected. Flooding to neighbouring streets may restrict your access to basic or emergency services.

What to Do During a Flood?

Unfortunately, even when you’re fully prepared, flooding may just be inevitable. Water rises and even the best flood defences can succumb to the power of nature. So what do you do during a flood? Well, the first thing to remember is that it’s critical you put people before property. Ensure you have co-operated with the emergency services before following this advice. If you are instructed to evacuate your home, evacuate immediately.

If safe to do so, ensure that you turn off gas, electricity and water supplies before flood water enters your home.

  • Secure yourself a clean source of water by gathering water in jugs, saucepans and the bathtub.
  • Gather torches, waterproofs, a first aid kit and any medication you need and move these items to a safe and high area
  • Move family, pets and any essential belongings upstairs or to a high place. It’s important you have a plan and a means for escape.
  • Remember that water and electricity do not mix. Do not touch any source of electricity while stood in water.
  • Keep listening to local radio for updates or call the Environment Agency Floodline on 0845 988 1188
  • Call 999 if you are in danger

How to Prevent Flood Damage

With an estimated bill of one billion pounds generated by flooding in the UK each year it’s never been more essential to ensure your home is protected from flood damage.

It’s not just the potential costs that make flood protection so important, on the more severe level floods can kill and at the less severe, but still highly important, you have the loss of precious memories.

Nobody, not even Chuck Norris himself, can control the weather so it’s not a foolproof plan to believe you can simply prevent flooding. However, there are precautions you can take to prevent or minimise the damage it can cause.

1. Plan Ahead

In a recent survey of people living in areas with a direct flood threat only 50% were aware that there home was at risk. Out of the 50% who knew they were at risk of a flood threat, only 60% had a plan in place for preventing flood damage. The first step is to be aware of how often you may face a flood risk and set up the necessary alerts to ensure you are aware of possible flooding.

2. Determine the Grading of Your Home

Most homes are built with the purpose of draining water away from the structure. Whether a new or old build, it’s worth checking the water flow of your home. This involves simply watching how water accumulates during an average rainstorm. Does it flow away from your home, towards your home or does it pool and stand easily? If you live in an area where standing water is fairly common you may want to talk to your council. If your house is in particular danger they have a responsibility to minimise danger.

3. Blocking Water Out

It may be impossible to keep all the water out of your home, but you can at least reduce the amount that gets in. Sandbags are a good start but also consider drains and ensure sinks and bathtubs are plugged up to stop water entering through these holes.

4. Move Objects

When flood warnings are raised, move as many of your positions out the flood’s path. Electronics, furniture, and anything else that is moveable and may be vulnerable to water damage should be moved upstairs. This may seem like an obvious solution, but when the waters start to rise, it can be difficult to move items quickly; therefore it is essential to be prepared. This is a very simple, easy way to prevent significant and costly damage to your possessions.

5. Invest in a Submersible Pump

Let’s say you live in an area at high risk of flooding, one of the best pieces of equipment that you can own is a submersible pump. If floodwater gets into your home, you should try and remove the water as quickly as possible. They can be useful in the event of a clean-up too and if you do flood you may minimise damage by pumping out water when it comes in.

What is a Submersible Pump?

As the name suggest submersible pumps are capable of operating under water. Often used for the drainage of ponds, swimming pools and drainage systems, they can also be used in the event of flooding.

Just in case you were wondering, yes, the device is hermetically sealed and the motor is close coupled to the body of the pump. This ensures that water cannot enter the internals of the pump and come into contact with electrical components. As I’m sure you aware, electricity and water should not be mixed and only an approved submersible pump from a quality pump dealer should be under water.

How Does a Submersible Work?

While this explanation is on the technical side, it’s worth knowing. Simply a submersible pump pushes water to the surface by pulling water into the pump through the intake, when inside the rotation of the impeller pushes the water through a diffuser. The water is then pumped to the surface.

The great thing about submersible pumps is that there is a variety of pumps designed for different uses. For example, a pump used to drain water from a basement will come with a float switch. This ensures that the pump comes into operation when the water reaches a certain level and stops working before the water runs dry.

Using a Submersible Pump for Flood Clearance

If you need a portable pump to clear flood water other factors come into play. It needs to have a filter to prevent it being blocked by debris; in addition, you need to take into account the length of hose so that you can safely discharge water away from the property and the length of the power cable to ensure you can safely run the pump from a dry electrical supply. Ensure the supply is protected by an ECB for safety.

To avoid confusion when purchasing a submersible pump for a flooding event, we advise that you purchase a purpose built flood kit. Grundfos Unilift B-CC7 Multi-Box Submersible Drainage Set for example is the ideal pump for a flooding event as you get the a suitable pump type, a multi-functional filter box, a 15 m discharge hose and an additional CC connector that fits several sizes of hoses.

It is important to note that flooding is severe and affects house electricity. In the event that power is cut during a flood, you will need to ensure you have a petrol driven generator to hand. With this in mind, particularly in badly flooded areas, there is no where to pump the water too and it will just come back into the property as drains are usually blocked. Consider carefully how you pump the water and where you pump it too.

How to Clean Up Flood water

Water in your home can range from minor inconvenience to complete disaster. Where you land on this spectrum will depend entirely on how much water gets into your home and how long it remains in your home. If time is on your side, the best case scenario is a few damaged possessions, and the worst you’re looking at structural damage. Remember, the longer you leave water in your home the more chance you create the perfect breeding ground for mold. It’s important to remove mold quickly as it can lead to respiratory problems including asthma and potentially severe illness.

If water does enter your home here is your checklist to minimise damage and remove water quickly and safely.

1. Disconnect the Power

Electricity and water do not mix. Do stand in water or attempt to clear water with the power connected. After the power is connected then remove electrical items. Salvage electrical equipment first. You may still be able to dry and save water damaged electrical items if you remove them from water as soon as possible. Follow these tips for drying out technological items by Intel here.

2. Removing the Water

If you’ve followed the above advice you should have disconnected your electricity and removed easy to move items. The next step is getting the water out of your home. The manual method using a bucket is effective but also energy sapping and time consuming. As mentioned earlier in this article, it is critical that you remove water as soon as possible to prevent extensive damage.

The quickest way to remove flood water from your home is to invest in a submersible pump. The pumps quickly intake water and eject it using an impeller system. If you purchase a dedicated flood kit you will also be prepared to remove flooding in the quickest time frame. These pumps also come with an electric and manual option.

Getting Rid of Contaminated Items

If you have contaminated furniture or other items polluted by chemicals or sewage during a flood you can contact the environmental health department to have them removed. Contact them here.

3. Dry, Dry, Dry

Just because the water is finally out of your home doesn’t mean its job done. First, open all your windows and allow air to circulate your home. Mop dry as much of the left over water as possible and then use hand towels to hand dry floors and walls. You may have to cut way drywall that was affected by water as it will eventually crumble and you will also want to remove wall paper as it can become the perfect growth area for mold.

4. Disinfect

Flood waters can easily mix with sewage waters from drainage systems or toilets. This unfortunately means that all sorts of nasty bacteria could be lurking in your home. Disinfect all areas affected by flood waters. This will include walls, floors, furniture and any items that sat in flood water.

5. Consider Mold Growth

Your home is finally dry and you may have already moved back in, but you’re not quite finished yet. It’s important to stay vigilant of mold. There are some supermarket products that purposely stop mold and may be worth the investment.

Essential Contact in a Flood

In the event of a flood it’s important that you have all the correct contact information. You may have limited access to the internet during a flood and it’s essential you have access to the correct services at hand. Print out this list and stick it to the back of a cupboard in a safe to access area. As usual, in the event that you or someone you know is in life threatening danger dial 999.

KSB Launch New Range of Energy Efficient Submersible Borehole Pumps

Energy Efficient Pumps

KSB Pumps have specialised in the production of water pumps, valves and systems for over 140 years and their products and services keep the world’s domestic, commercial and industrial water supplies running.

With more than 80 years’ experience in the design, development and implementation of borehole pumps alone, KSB are a world-leader in waste water management systems and can be relied upon to deliver not only reliable, high-performance pumps, but outstanding advice and customer service too.

However, despite being well-established experts in their field, KSB are not a company to rest on their laurels.

With their eye on the water management needs of the future, their experienced network of engineers and developers have been working hard to press forward with innovative new products and their latest lines have just been revealed at the 2016 IFAT.

IFAT is the world-leading International Trade Fair for Water, Sewage, Waste and Raw Materials Management, and it attracts exhibitors from all over the world who network, trade, promote their products and discuss the future of the water management industry.

It was here that, among more than 3000 of the world’s most respected companies, KSB Pumps revealed its new UPA range of energy efficient, dirty water submersible pumps.

These new energy saving borehole pumps offer users and the environment a number of advantages over other synchronous or asynchronous alternatives:

Green Credentials

Every organisation has a responsibility to update its technologies to the most energy efficient standards available to reduce their carbon footprint.

These new KSB UPA pumps enable companies to do that, but from a commercial perspective, they also enable organisations to increase their green credentials without incurring additional costs or compromising on performance and efficiency.

Performance and Efficiency

With in-built, ‘permanent, magnet excited synchronous motors’ the new KSB submersible pumps offer a high-performance output that ‘clearly exceeds that of conventional asynchronous motors’ without developing excessive heat.

This has been achieved with:

  • Frequency inverters that optimise and adjust flow rates to regulate and reduce the frequency of pump starts, paired with patented sand separators which extend the pump’s life.
  • A stainless steel and hard carbon construction that operates continuously and removes the need for maintenance.
  • Mechanical seals that prevent waste fluid from mixing with motor fluid to increase the performance and availability of the motor.
  • Dynamically balanced rotors that ensure smooth running.
  • Lubricated, self-adjusting tilting pads inside the thrust bearings plus counter-thrust bearings that absorb hydraulic axial thrust to protect the impellers and prevent them from coming into contact with the casings.

Cost Reduction

The cleverly engineered design and construction of the new KSB UPA pump means that users can enjoy increased efficiency and lower running costs.

With a reduction in the energy required to power the pump, immediate and ‘enormous savings’ can be made on operational costs but in the long-term, there are other significant savings to be made.

The construction of the casings and its internal workings ensures an extended life, while the maintenance-free reliability it offers reduces the potential costs of down-time due to mechanical errors and any associated labour costs for repairs.

In comparison with other submersible borehole water pumps currently available, any outlay made will be recouped quickly to generate a swift return on the investment.

Choice of Applications

With a motor and pump system officially certified for use with drinking water, the new UPA pump series has a number of applications to ensure that both individuals and organisations can enjoy the benefits of them.

A choice of different metal variants are available, so any aggressive fluids can easily be managed with the stainless steel pump sets of 8 inches and above, while the increased output on offer means they are suitable for use with larger pumps to manage flow rates of up to 850 cubic meters per second.

This makes them ideal for handling clean or dirty water for:

  •         Irrigation and drainage
  •         Pressure boosting
  •         Industrial and residential water supplies
  •         Groundwater management
  •         Raw or service water supplies

Summer Flooding Tips to Protect your Home from Floods


More than five million people in Britain live with the imminent danger of being flooded from the sea or rivers. The risk of urban floods caused by extreme rainfall or poor drainage is also a risk for many. Here are a few simple steps that will protect your home from the worst of flooding.

Submersible pumps

Firstly, check with the Environment Agency on your property’s flood risk. Other private agencies and the Association of British Insurers also have maps of flood risk areas. This will help you to prepare for the flooding threat.

Start with the exterior of the house to stop any floodwater from entering into it. You can install front and back doors with built-in flood protection. Otherwise, stock up on sandbags that you can place outside the door when a flood is forecast.

Protect airbricks in the external walls with special covers that you can buy from DIY stores. These covers can easily clip in place.

If floodwater does enter the home despite this protection, you have to be able to protect carpets and furniture. Floodwater usually rises through the cellar or crawl space of a house. This is where submersible pumps find their use. The best strategy would be to seek the advice of a flood risk experts, who know where to locate submersible pumps so that they expel floodwater from below the house before it rises through the ground floor.

Floodwater will also rise via pipework and the toilet and even through washing machine outlets. So it is important to block these once a flood has been forecast. These problems can be solved by installing backflow valves on the drains and outlets and a toilet bung in the bowl to stop floodwater from rising up there.

Floodwater will always exploit the easiest entrances into any building. Check for any cracked bricks and mortar on the external walls of the house to ensure that these will not become floodwater inlets.

Anchor Pumps Launch Range of Emergency Flood Kits

Coping with a sudden flood and its aftermath can often be a difficult experience. It takes time, knowledge and the correct equipment to restore some level of normality to your home or business.

This has been the case of many households throughout Britain during the 2014-15 winters; the wettest recorded for over a century. Many areas in the UK remain at risk of further flooding during spring and autumn in addition to the potential for unusual or flash flooding during the summer.

After salvaging furnishing such as sofas and carpets wherever possible, it is necessary to strip the affected area to bare floorboards and concrete so that drying can begin. However, before the restoration process can commence, the daunting task is removing large volumes of flood water, and this is where emergency flood kits are needed.

After high demand from customers, the team here at have created a new range of complete emergency flood kids, specifically designed to protect from and clear up flood damage in both domestic and commercial properties. They consist of submersible pumps and accessories, essential in case of a flood emergency, and we have already seen many householders and business clients preparing themselves by purchasing and storing these kits in readiness;

floodkit1 (1)

The emergency flood kit consists of:

1. A Wilo Drain TMW 32/11/B, 24 watt water cooled basement drainage pump. This is suitable for stationary and fully automatic operation. The pump generates a continuing turbulence around its suction area. As a result there is no generation of odours related to the flooding and sediment settling is eliminated. A fluid that circulates between the pump shroud and its outside housing is cooled to prevent overheating during prolonged operation.

2. A Carry Cage that can be used to filter away leaves and other debris.

3. A 10-metre, weather resistant, Layflat hose. These hoses are collapsible, strong and very flexible. They are commonly used for agricultural and industrial water pumping as well as for domestic emergency flood kits.

4. A ¼-inch width Hosetail clip made in zinc-plated mild steel that will connect the pump and the hose. Its tough design means that it will withstand use in adverse conditions.

5. ¼-inch Camlock Couplings that fit between the pump and the hose. These are vital to connect the hose, tank and other fittings. These couplings can be made of stainless steel, aluminium, polypropylene, fibreglass as well as reinforced nylon to suit the nature of the liquid being pumped.

As Britain’s leading distributor of domestic and industrial pumps, Anchor Pumps has been a major player in the UK pump industry since 1976 and are pleased to be adding a new range of products to its ever growing online categories.
