I have an older PAR diaphragm
pump which has been awesome and practically indestructible. In fact I have serviced it from death a few times on this trip across the Pacific. Always has been working great.
Now, for some reason, the flow is limited and when the faucets are off, it still runs. You can hear the pressure build and the pump work harder against it, but it never actually shuts off.
Have completely re-built it. Again. No crap in the valves, no leaks
from the pump body. Water
flows through all faucets (but with less than formal capacity). New diaphragm
not long ago.
Any suggestions? Please?!
part of Fiji
with very limited (read none) access to spare parts
or new pumps so please don't just post a link to a new Jabsco
pump for sale
on eBay or something
