Your flush pump has a number of parts that will require replacing over time. We carry spare parts for all our pumps and most likely you will require a diaphragm, inlet and outlet valve for a hand pump. Some foot pumps require a new boot/diaphragm.
Our main pumps are the Whale Compac hand pump (silver handles with a rubber grip) in the Executive and Ultra. Our foots pumps have changed over the years with early models (before 2016) with a rubber cover and internal diaphragm, inlet and outlet. Our recent pumps install with a Merlin Pump have a boot diaphragm.
Our early toilets have a Chimp Henderson pump with a red handle and octagonal diaphragm, inlet and outlet valve.
