Nice looking pool Duckhunter! :thumbsup:
We have a similar sized pool. I've had to fill it from empty three time due to:
1. Initial installation about 15 years ago.
2. New liner after moles undermined the pool and it burst (not fun).
3. New pool last year (the original was a 15 year old previously used free pool someone gave us and started rusting after 30 years).
I found that if I put three garden hoses on it wide open, our well pump would stay on and maintain about 30 psi steady and not cycle off and on. It takes just about 17 hours to fill the 12,500 gallon pool. So, it was a two day job since you don't want it to run overnight. Everyone's well is different. Ours is 4" and can produce 15-20 gpm all day long when wide open.
Volunteer FD used to bring water out in our area for a donation. They ceased that due to insurance liability.
As for our pool, I converted it to salt water about 4 years ago and am very happy with the results. When I open our pool, I top off the water, add about 2 bags of solar salt, 5-6 gallons of household bleach, some CYA and off I go. No more chemicals all year long. I only have to add salt if the pool overflows from rain and dilutes it. I have to add water due to evaporation when it drops more than two inches from my full line. Otherwise it throws the salt balance too high. No algae since I converted to salt water. Soft water. Same salt concentration as human tears. I recommend it highly. The salt water chloring generator uses electricity, but I don't have to mess with chemicals all year. Its a good trade off for me. At winterization, I wait until the water drops below 50 degrees during the day. I drain it below the plumbing, add 5-6 gallons of bleach and put the cover on. That's it.
Enjoy your pool!
