Shurflow pump does not turn off

[tim198]

turn power on pump runs can hear some pressure build up but does not stop. No Leaks. any ideas, can you replace the pressure switch?

There is an adjustment on the pressure switch and the bypass diaphragm. Look up the online manual for your model and the instructions on how to adjust will be there. I had to do this to my new pump last week after the install.

Did you open the faucets and "burp" the air out of the system while you had the pump running? I have to do this every year when running the pump for the first time during de-winterization.

Tim198-

Which model is it?

I had one of the Shurflo Extreme pumps with the microprocessor control that was supposed to be the cat's behind. It was nothing but trouble and didn't shut off. Luckily my water heater had overpressure protection so I didn't burst a line. I've had good luck for several years with the much simpler versions of their pumps.

Tim,
Winestream is probably on the right track. I have had to bleed air simply by running water. This has been common in several trailers I have owned.

Depending on how the trailer was winterized an area where air may be trapped and simple bleeding will not get it out is the section of pipe from the city connection to the rest of the system. If bleeding does not stop it attach the city connection and see if air comes out a faucet.

I only get my pump keep running when my fresh water tank is empty and the pump keep running to get the discharge pressure up to the set point. Also the air leak on intake side of the pump may cause it run.

Thanks for helping a newbie. I took the pump out of the circuit and put a gauge on it went to40 psi and shut off. Will now show check the lines. Thx again.

Problem solved!....checked lines and found the compression valve (the loop by the water tank, near the pump) that allows water into the tank from the street side hookup had a loose compression fitting and was sucking air into the lines preventing pressure build up.
