In an attempt to diagnose a water pump problem I have been reading the myriad of answers to pump problems using the search facility - to the extent that my head is now pretty much scrambled.
Symptoms are running more or less continuously when taps are turned off.
Turning any tap on gives a significant spurt of water followed by normal running.
Turning taps off turns pump off but it switches on again without demand after about five minutes.
Turning pump off at selector at this stage and leaving for a while results in protracted running when subsequently selected on.
My "diagnosis" is an internal leak in the pump allowing water to flow back through the pump into the tank thus requiring priming each time I switch on or if taps are left off for a while.
I would be grateful for any comments on this.
The current pump is a Posiflo 3000-151-2000 7L/min 20 psi which I believe is now obsolete and may be replaced by a Shurflo Trail King 7L/20 psi.
Words of wisdom would be much appreciated.
