Pump pulsing when demand stops
Ok, I have combed this and other forums with no success. I'm hoping someone can shed some light.
I have a 2016 27bhs. We are having a problem with the pump. When flushing the toilet, when the pedal is released, the pump pulses for 3-4 seconds before stopping. It's not the same as the pulse you have when it is low demand, it is more a jackhammer type pulse.
To add, I installed a pressure tank to try to resolve this as well as cut back on how often the pump runs over night with my wife getting up.
After installing the tank, the pulsing is worse when flushing . Now it will pulse for 10-15 seconds and does so almost every time the toilet flushes . The pulsing stops if I crack the kitchen sink cold water for a second. I've checked and tried changing the pressure on the tank with no success and the dealer gives the "it's normal" line. Any suggestions? I have insured there is no air in the lines so I give up!
