Submersible pump well,Dole flow control valve whistling
Hi
I have recently bought a home with a well system which is new terrain for me.. The line from the pump to the pressure tank has developed an intermittent whistle/high pitched hum that I have narrowed down to the Dole flow control valve. The whistling has gradually become more constant...
The flow control valve is 4 GPM
I don't know what model of submersible pump I have, but believe it to be a 1/2 HP gould.
I lose volume and pressure with too much demand on the system ( A sprinkler zone and running a tap in the home )
I am wondering if my pump is weak or if perhaps my well cannot keep up with the demand.
Any help /suggestions would be appreciated...
Thanks Troy
