I'm in my 4th year of owning a pool and have decided to replace the pump and filter.
I have a 20x40 in ground plaster/gunite pool. 3 ft to 9 ft @ 36000 gallons. The pool was built in 1984 and has been maintained very well. Current pump is a 2 HP MagneTek Centurion with a cartridge filter. Filter size/capacity is unknown as any and all marking have either fade or are missing. I can tell you that it is a stainless steel drum that holds 3 cartridges.
From the looks of the pump and filter it may be the original equipment from when the pool was built but I have no idea for sure. Both still function but their time is limited and I'm trying to be proactive.
I'm attaching a pdf of the layout with the lengths of the PVC runs. The pool has 8 floor cleaning jets that run off a central location. I have no idea how the PVC runs to the jets. There are 5 PVC runs from the control box and how the 5 runs connect to the 8 ports is unknown. The pool is also built into the side of a hill and the pump and filter sit 2 to 3 feet below the pool deck level so all PVC runs are up hill except for maybe the floor drain on the 9 ft end and some of the floor jets.
I'd like to put in a quite 2 speed pump with a slightly oversized filter since the PVC is only 1-1/2. Looking for pump specs, filter sizing and recommendations. Any help would be appreciated.
