The valve in the line from the pool vacuum and the pump opens

Customer Question

The valve in the line from the pool vacuum and the pump opens each time the pump starts. When I hand close it operates normally all the time the pump operates. The pool pump pressure gage indicates 18. The problem valve has been checked by a professional. What should I do to get the valve functionally?

A clogged breather tube, located on the filter,
can cause pressure to surge when the pump
cuts on.
Another cause is some returns are turned off
that should be open.
Make sure your pressure gauge is accurate.
10-20 pounds should be. If it is much higher
your pump could be too large or you
may have an air intake leak.'
If the pump has had trouble priming
that could be the case.
Any place where the line could be clogged
blocked filter intake by debris. Customer
