Failing to maintain your pumping system may drastically increase the risk of failure and likelihood of your basement flooding. If you have a sump and pump system installed as part of your basement waterproofing scheme (usually a Cavity drain membrane system - often referred to as a Newton or Delta system), ensuring that this equipment is fully functioning and capable of discharging water when required is essential to protect your basement. After all, it is likely that the sump and pump is at the heart your waterproofing defence and if the water cannot be removed, your basement may be at risk of flooding when a reliable pump is most needed.
