Happy Thanksgiving to all. I need some help from this learned Forum. I replaced my Whisperflo 1.5 HP with an Intelliflo VS-SVRS. My problem is that with the sloar on (two story house), the pump will not even prime at times. If I turn off the solar valve, the pump primes OK, but after it stabilizes, the SVRS Kicks-in and it stops as if it would detect blockage. I then restart and it works fine. Never had any problems with the Whisperflo. I also just checked starting prime with empty lines and it primes in less than 10 seconds to full basket and no air. One thing I did noticed: When I move the three way valve so I get vaccum from the dedicated sweep line, I hear noise (like air or bubbles) in the suction side and vaccum gauge drops about 3-4" hg. I don't know if that indicates vaccum line air leak.
My readings with the solar on are:
at 3110 RPM, Vaccum 18 and Pressure 22+3 for a total dynamic head of 78 (with solar off, total dynamic head is 60)
at 2700 RPM, Vaccum 13 and Pressure 16+3 for a total dynamic head of 58 (with solar off, total dynamic head is 55)
Any suggestions on what could be wrong? I am concerned that even using automation for the solar to kick in after the pump is running will not help because the SVRS turns it off and then back on.
Any way to disable the SVRS sensor? Thanks.
