hi i recently had to drain down the cold supply to this pump to replace a leaking push fitting.
on re-filling there is something like 5 seconds delay before the water arrived under pressure while before it was instant.
im assuming its an air lock but if so how can i clear it.
also there's a non return valve on the cold feed from the pump, would that have anything to do with it?
the hot is working fine its just the cold which has the problem
any ideas appreciated
thanks
