Evaporation

I know this is a difficult question to answer but I figured its worth a forum shot.

Our IG, vinyl pool is in direct sun here in Connecticut. It was recently built and filled about 2 weeks ago for the first time. We have had some dry spells and some rain over the last few weeks but the water level has dropped 3-4". Is that normal? There has been no swimming and I am trying to figure out if there is a leak or if that is normal. Nights have been down to the mid 30s and highs have been high 70s lately. Not sure if these extreme temperature shifts cause faster evaporation?

I am a little concerned because I did have one leak already they found. Not really a leak but they forgot to connect a return line tonthe pukp and so the water was leaking out underground near the pump. Now I am concerned something else is wrong. Also, I have two skimmers and one sucks way more debris than the other. Is that normal?

anything over a 1/2 inch daily (on the East Coast) and I would suspect a leak. 1/4 inch is usually evaporation. Quite a bit more in the desert Southwest, etc.

Thanks Dave. Is there a rule of thumb calculation how much water it would take to bring the pool back up to a certain level?

If you know the surface area of the pool:

Gallons = Surface Area (sq-ft) * Water Rise (in) / 12 * 7.48
