I'm driving myself nuts (not much effort required!). The story:

Last season, first sail the hot water system blew off the tail to the tap in the heads sink and proceeded to dump all the fresh into the bilge. Since then I've not been able to get much to work, so last weeekend I got stuck in. I partially filled the fresh water tanks with about 5 galls, couldn't get the (Shurflo) pump to pick anyhting up, replaced the valve set and everything seemed to be going fine. Cold water side is fine, but despite running for ages the HW side contiunes to blow air out. With a pressurised system, should I use the pressure relief on the calorifier to help bleed air out, or should I just let th barstewarding thing pump? Or should I wait for warmer weather and put more water in?

TIA
 
Assuming it only pumps when you turn a hot tap on, then I'd leave it to pump the air out. It won't help to open the PRV - the pump still has to fill the calorifier. Dependant on the volume of your calorifier it'll take a while to fill. (I'm assuming the calorifier is higher than the water tank)

Hopefully you've now put more than a few gals in the water tank - or you'll be pumping air into the calorifier rather than water. /forums/images/graemlins/smile.gif
