My pool is not very old (almost 4 yrs old) but the filter, pump and skimmer have been a real pain to work with. The spider valve is hard to turn, it leaks, the clear cap on the pump basket is cracked and extremely hard to get off. It constantly sucks air and when I connect my vacuum to it, it only runs so long until it looses prime from too much air. I am now looking to replace it with a cartridge filter and pump along with a Hayward skimmer. It will be hard plumbed to the pool too.
I need advice on brand and size of the filter/pump. I also need to know what I need to hard plumb it. Unions, PVS, cut offs, things like that. My son is a certified plumber so he will do the install but I have to buy the parts so I want to get everything he will need. I want to be able to turn it off and cut the water flow to the filter and pump so they can be taken out if needed for repair or cleaning. I also need to know how long a cartridge filter lasts and can they be cleaned and reused?
My pool is 18x34 and depth of 4 - 7.5 ft. 22800 gallons. This is my current setup.
