Hi,
I have just refilled the water system on our boat after it has been laid up/winterised for app 3 years and all is/was well with no leaks, I left it alone for 2 hours at least and the pump didn't re-pressurise but when I closed the doors to the cup'd where the pumps are (one system for hot and one for cold), there was a very slight sound which sounded very much to me like an escape of air not water - there is no sign of any moisture even on a very close inspection so lets assume its air from the accumulators?? 2x Shurflo 181-203
Do I simply replace them, are they serviceable, or could it be something else.
All help gratefully received, particularly if its a quick check as they will only cost me £90 to replace them both and there's easy access to do it so not the end of the world.
Yes £90 is a lot of money but I allowed for problems like this when we bought so there is a kitty!
Cheers
J
