I have a Stuart ST55 pump that supplies cold water directly from an attic tank and hot from a hot water tank to a shower head. It has worked fine for year but this week I drained the cold water tank in the attic and since I refilled it I am having a problem.
If I turn the shower on hot only or cold only it works fine but if I tuen the mixer to add equal hot and cold the shower stops and starts as if there is an air lock? Any help would be appreciated.
