My domestic water pump (jabsco model 31750) has a very slow leak (0.5 L/day) close to the base of the pressure sensor cover. I suspect a failed seal inside the cover. Any ideas please?
Thanks, that's what I did and found a lot of granular precipitate on the diaphragm which was probably preventing proper sealing. I have yet to refit and testTake it apart. Mine stopped leaking and worked better after cleaning it out.
Thanks, good idea for the future. However in my case the water was very much coming from the lowest part of the unit, well below the connectors (tissue wrapped around the connections remained dry) and it seems as if crystals forming on the diaphragms were obstructing its closure and giving a poor seal.Also worth changing the O rings on the inlet & outlet connectors. Mine was leaking & this fixed it.
I keep a selection box on board & matched them from that.
