Thinking caps on?

[Ralph L. Fullenwider]

Hi everyone:

Here is a fun one perhaps.

Water pump new, 5.7 gpm 65 psi

Pump cycles after initial pressure up. The cycle is a slight burp about
every 10 to 15 seconds. This normally indicates a water leak.

Kicker, I have been from one end of the pressure side of the piping and no
water leak. Only think I can think of at this point is perhaps crud in the
Sporlan valve allowing a seepage back into the system causing a slight drop
in pressure at the pump. The anti back flow valve seal is good, pulled it
and checked it out.

Ideas?

Safe travels,
