    Downgrade from 2.5 HP pump

    I did the head calculation using Pentair website. Link: Pump Calculator I am using 60 gpm as flow rate. This is coming from 5 nozzles * 12 gpm/nozzle = 60 gpm (spa). Pool flow rate will be small as 41.7 gpm for 8 hrs turn. My current jet is ok, with pretty much pressure with 2.5 HP pump only...

    Downgrade from 2.5 HP pump

    What is that standing pump for SPA? It is configured as AUX#1. When it is turned on, the jet spurs out very harsh. Is that booster good enough to compensate some loss of HP?

    Replacing pump motor

    Moved from here. What and from where do you replace the motor? I am in the same boat. Mine is JHPU 2.5 HP but too big for my pool. So I am thinking replacing it with a two speed motor.

    What to upgrade from a single speed Jandy 2.5HP

    Thanks everyone for the suggestions. The electric bill climbs up too much recently. It's the wife's order to reduce it now. It was my fault for the settings of the pump. The SWG was set as 60%. Now SWG is set as 100% and the run time is still under watch. But maybe 5 hr/day is the least in...

    New test results - Do I need to SLAM?

    Thanks, Maddie. The pool is not algae bloomed yet. The water is crystal clear, except there are debris in the shade upstairs that the cleaner can not reach. Some patches of wall are covered with green algae, about 3 places 3' x 4'. I did the test on last early evening and redo the test this...

    What to upgrade from a single speed Jandy 2.5HP

    Just becoming a new owner of the swimming pool. The Jandy JHPU 2.5HP single speed pump is 15 years old. It was run with a SWG for 8 hours a day. The bill could run up to $70 a month. Is it worthy to upgrade to a two-speed or VS pump? Seems pentair is recommended. The pool size is 19k, what...

    DE sands in pool

    Hi, Everyone, New to swimming pool and new to the forum too. I have a Pentair 60 DE filter with grids like fans. I had it recently dissembled and garden hose deep cleaned. I got it reassembled and refilled with DE from Lowes. The DE is weighed to the requirement from the Pentair manual. After...
