Sump Pumps
In order to select the correct cellar sump pump, first determine the vertical height difference in metres between the pump and its discharge point, then for every 10 metres of horizontal distance, add 2.5m. This gives your 'static head' - you need to ensure that you pump is capable of delivering this - check the 'Technical Specification' tab on the pump's page to ensure you don't exceed this. For example, the Ebara Best One MA and MS submersible water pumps have a maximum head of 9m.
