    Re: evaporation

    Where are you located, and how much sun exposure does the pool get in hours daily?

    Re: evaporation

    2-3" is a lot of evaporation. I' suggest you do a bucket test.

    1. Fill a 5 gal bucket about 2/3rds full of water.[/*:m:lu8cqm7b]
    2. Place the bucket on the top step in your pool.[/*:m:lu8cqm7b]
    3. Carefully mark or measure the water level in the bucket.[/*:m:lu8cqm7b]
    4. Carefully mark or measure the level in your pool.[/*:m:lu8cqm7b]
    5. Wait about a day and measure the levels again.[/*:m:lu8cqm7b]
    If the bucket and pool loses the same amount it's evaporation. If the pool loses more than the bucket you have a leak.

    Re: evaporation

    If your 2-3" estimate is pretty accurate, you have a leak.

    Re: evaporation

    i am in south carolina and the pool is in direct sunlight about 80% of the day. my wife says that it is more like 2-3 in every 2-3 days. that still seems kinda high to me.
    I will try to do the bucket test in a couple days. i never thought of that. i have looked for a wet spot around the pool but can not find one but i guess i could still have a leak even thought i cant see water on the ground any where

    Re: evaporation

    well i found out where my water was going. when the pump runs at night it leaks out of the discharge hose. what would cause that?

    Re: evaporation

    You mean it leaks out of the waste hose on the multiport?

    Bad spider gasket is the most likely suspect.

    Re: evaporation

    yep that is where it is leaking at. it only leaks out there when the pump runs and it is a slow stady stream.

    Re: evaporation

    I agree w/ Bama; the spider gasket is almost certainly your problem. Easy, cheap fix!
