We bought a house two years ago with an in ground pool. Pool is 22 yrs old, can't find original installer.
I have had several pool companies give me their opinion as to the # of gallons and they estimates range from 5,000 to 7,500. It's kidney shaped, 10' X 20'. Deep end is 5' , shallow end just shy of 3'.
Anyone have an idea how I can narrow down the capacity range?
