One of my flo-jets was producing about 25% less pressure than the other in the "main van". So after checking that all hoses, connectors and such were like for like we swapped one from the "second van" and it has a higher pressure and so I've kept it in place.
Now the "old" pump still works ok but is not so powerful.
Where can I get spares like O rings and diaphragms for it?
Gardiners only list switches as a spare.
