We have been living for 6 years at our house and the pool is 18 years old. My backwash valve has been hard to read for several years. I never felt like I could change it because there is not enough room on the piping to cut the pipe and add a coupling. This year it looks like my booster pump has died. So now I am thinking of re-building everything from the ground up. New back wash valve, new booster pump and new main filter pump and add all new pipe. Is there anything I should read first or be aware of before starting this? I have a fare amount of plastic pipe work but I am not a plumber. This seems like a very doable job I am just afraid of the "what I don't knows".
I also want to take this time and replace my 2HP main filter pump with something smaller as I only have 15-16,000 gals. Not sure what size yet, but I know 2HP is too much. Thanks for any help
