I replaced my pool plumbing with a Triton TR100 and Pentair Whisperflo WFE-3. I added my Polaris PB4-60 booster back into the system and am now experiencing a strange problem. When I start up the booster, it is having a very difficult time turning over. I immediately suspected debris so I turned the shaft from the back of the pump to help it get started, there was no debris but the water pressure seemed to be fighting the rotation). The pump is running but is pulling over 20 Amps (I have a device called a Kill-a-Volt to monitor amps/hz) Since the pump has a listed operating amperage of 12.6, I thought there must be something internal to the pump. So, I went out and bought a new Polaris PB4-60 booster pump identical to the first pump. This new pump is having even more trouble turning over and is pulling about 24 amps before the 20 Amp fast blow fuse that I put into the wiring blew.
I have the input to the Polaris booster (center hole) driven off a 1 1/2" "T" downstream of the multiport. The output from the "T" is then reduced to about a 1/2" barber male fitting to connect to the garden hose size pipe) The output from the booster goes into a dedicated return pipe back to a single outlet for the creepy.
There is a restrictor in the creepy vent/connector that limits pressure to the creepy. Could it be that this restrictor is fighting the output of the booster and making the pump strain thereby increasing amps?? Any ideas??? THANKS
