Service Kits & Spares

Our Service Kits & Spares range covers pump service kits and spares for bilge and freshwater pumps – the wear parts (diaphragms, valves, seals) that keep a pump working reliably without needing a full replacement.

Pumps wear at predictable points – diaphragms, valves and seals are the parts that fail first, generally well before the pump motor or body itself gives out, so a service kit is usually a cheaper and faster fix than replacing the whole pump. Match the service kit exactly to your pump’s make and model, since parts aren’t interchangeable between manufacturers or even between different pump ranges from the same brand – check the model number on the pump itself before ordering rather than guessing from appearance alone. A pump that’s lost pressure, runs but doesn’t move water effectively, or cycles on and off more than usual often just needs its service kit replaced rather than a full new unit.

Keep a spare kit aboard for pumps that are hard to access or replace mid-trip, since a diaphragm or valve failure is a straightforward fix with the right kit in hand but a real inconvenience without one.

Frequently asked questions

How do I know if my pump needs a service kit rather than full replacement?

If it’s lost pressure, runs but doesn’t move water effectively, or cycles unusually, it often just needs its diaphragm, valve or seals replaced rather than a full new unit.

Are pump service kits interchangeable between brands?

No – match the kit exactly to your pump’s make and model, checking the model number on the pump itself before ordering.

Should I carry a spare service kit aboard?

Worth doing for pumps that are hard to access or replace mid-trip – a worn diaphragm or valve is a quick fix with the right kit but inconvenient without one.
