I had a solar heater installed, and my pool pump is not strong enough to push to the water fast enough. It is going up 2 stories and through 3 seperate banks of solar panels (total of 12). Lots of air bubbles in the line, the installer took off the vacum relief valve and there was a trickle of water comming out. The manufacture says it should have been comming out full bore.
I have a jacuzzi cygnet 1HP pump right now. The pipes going to/from the pool are 1.5", the pipes going to the solar panels are all 2" (manufacture wanted 2" even though the rest of the pipes were 1.5"). 1 skimmer, 1 main drain, 5 returns (2 main, 1 pool cleaner, 2 step).
I was looking at the Hayward Northstar series because of the energy rating and high head specs.
My question... should I go with the 1HP full rated pump or the 1.5HP full rated pump (can't go any higher as I only have 120V service)?
Any good way for me to figure out what I need?
