The Bypass kit consists of two adaptors which push-fit to the outlet connectors of the Pump before fitting the Hoses. The adaptors are connected by a small bore flexible tube. If a twin-ended pump is then run with one supply closed off on the outlet side i.e. basin or bath taps, toilet cisterns, washing machines, dishwashers, etc. the By-Pass Kit will ensure that the closed end of the pump maintains a low flow of water to prevent overheating and subsequent seal damage. The By-Pass Kit can be retrofitted to any existing installation.
