I've decided I need a new pump and filter (probably DE) and need some help on the size , kind, and brand and probably something I'm forgetting. I've done a little research but who knows if it was the right kind. This is the information I calculated from one website.
Oval shaped inground pool roughly 15' x 30' x 5.25' (average depth 7' + 3.5'/2) x 5.9 = 13,938 gallons, so 14,000 Gallons.
14,000 gallons/ 8 hours =1750 gallons per hour or 29 gallons per minute
14,000 gallons/ 10 hours = 1400 gallons per hour or 23 gallons per minute
I think those calculations are fairly accurate but I get confused with feet of head partially because I don't know exactly how my pool is plumbed besides from being 1 1/2" pipe. Attached is a sloppy drawing and a picture of the pool. In the picture of the pool if you can see there are 3 buckets placed on the right side which represent the jets and the pink jug is the skimmer.
Based on the information I have given, can you please direct me to how much feet of head I have, along with what size pump and filter I should get and any other information you can add would be great.
Thanks so much in advance!
