Sump and Pump - What You Need to Know

At the heart of any basement, there needs to be a basement waterproofing system to keep the environment dry. An important aspect of any basement waterproofing is the sump and pump system. This is designed to remove ground water from within basements including any water collected from cavity drain membranes. The sump and pump system provides homeowners with peace of mind, protecting them against flood risks and severe weather conditions.

How Do Sump and Pump Systems Work?

A specially designed sump chamber is usually installed at the lowest point of a basement. When water drains to the sump chamber, a submersible pump then pumps the water away through internal pipes to a safe evacuation point like an external drain. These pipes are fitted with one-way valves to stop water flowing back into the basement.  

Where cavity wall membranes are used as part of a basement waterproofing system, water is directed through the cavity and then via basement drainage channels to a sump chamber where the pump then evacuates the water to an external drain.

Please note: a sump pump system is not designed for foul water. See our guide on foul pump systems for more information

Why Do I Need a Sump and Pump System?

Every home that has a basement should invest in a sump and pump system as they provide a reliable way of dealing with water ingress. When used in conjunction with cavity drain systems like PermaSEAL they work as a system to provide a dry basement. Many homeowners can then use the new space to store valued possessions or simply as extra dry habitable space.

Preventing Flooding 

It seems like more and more cases of flooding are occurring each year in the UK. Climate change and the resulting extreme weather, has meant that severe flooding is now a regular occurrence across the country. In particular it effects low-lying areas like the South West. If your home floods, it can have a devastating impact, with significant damage resulting in huge costs, treasured possessions being ruined, and even homelessness.

The installation of a cavity drain membrane system with a sump and pump system can help reduce the risk of flooding. It not only provides protection for your basement and home against flooding; it will also protect your most valuable possessions making it a great investment in your home.

Important Features of a Sump and Pump System 

-       Fully Serviceable – Although they require little maintenance once installed, it is important that you can access the unit. A quick release shut-off valve for servicing the pump is a must. 

-       Dual Pumps - The dual pump system reduces the risk of flooding significantly more than a normal pump system, because the secondary pump is in place, continuing to pump even if the first pump fails to operate. Our PermaSEAL dual sump pump uses two identical SV-150 pumps.

-       Alternative Power – It is important that the system can still work even during a power cut (these can be common during storms). By adding a PermaSEAL Battery Back Up System, it ensures the pumps are supplied with power, allowing them to operate for a period of time during a power cut.

-       Alarm – As a further precaution, an alarm is a good feature to detect high levels of water. The alarm will sound if the water rises above the normal operating level within the chamber. Powered by a 9V battery, the alarm can be programmed to automatically reset or manual reset after the alarm has sounded. You have the option to mute the alarm after an occurrence by pressing the mute button. The red alert light will continue to flash after the alarm has been muted.
