Fill water next day?

So the pool installer who was recommended by the pool store and who had installed my friends pools went over the timing with me today for our install. We are scheduled for Friday and they asked for the water to go in Saturday. They will leave the pool with 4-5" of water on Friday as they want the liner to stretch in the sun a day before filing up all the way. They specifically said to wait till it warms up Sunday to put the water in so not first thing in the morning. Does that sounds right? It is an oval and I am concerned with the framework sitting overnight without water.
 
4-5" of water in a 15x30 is over 10 thousand pounds of water holding the liner and walls down. Short of a pretty major wind storm I wouldn't be too worried about the pool.

At the same time I'm not sure why they are soo worried about the liner stretching and taking time to fill the pool. Mine was put up in the morning and they had a water truck dump 6k gallons as soon as soon as they finished the installation. Would have been two water trucks to fill it up right then and there but I didn't feel like paying for the water when I have a perfectly good well.
 
When my pool was put up They told me to fill until the sun was off the pool and wait until the sun was back on the next day to finish. They said liner needed to warm up, but it was March.
 
When they were installing my pool in August,the installers stopped what they were doing for the day because it was a bit too windy and had to come back the next day to finish installing the wall, caps, etc. The next day they laid the liner out in the sun and then installed the wall and then put the liner in. I had a water truck there with 4000 gallons and pumped it all in within a half an hour. A second truck came and filled it up again an hour later. I filled the rest through my hose. The wall is a fairly large and flimsy piece of metal. Without the water pushing out it can collapse fairly easy.
I think it really comes down to the experience/history of the installer and what they prefer. I personally would turn on the hose and start filling right away because it's going to take multiple hours and I wouldn't want it sitting there without water in it. Ground water is cold anyway and will negate any sun exposure once it's covering that part of the liner. Sure 6 inches of water is a lot of weight but it still won't stop the tops of the pool from caving in with high winds.
 
I should provide some more information. They will warranty to the pool. We have well water so I can't be using that much of our own. I have to bring in water trucks. We don't really get wind in our area unless there's a storm happening. it's fairly sheltered where I am.

I was just wondering if anyone else had a pool company do the same.

With that said, my installer specifically said that it couldn't wait to be filled with water. I "had" to have at least one water truck available within an hour after they set the liner. Those instructions were part of the contract I signed with the installers.
So the initial 4k gallons probably filled it 16" or so.
 
So I called the water truck to schedule it and I asked them. They said it's pretty common because the pool installers want to let the liner sit for a bit with just a little water in it to see if there's any issues before filling it all the way. She said because if it does split you won't lose hundreds of dollars of water

How do I figure out how many gallons 4 inches of water over 18 x 33 would be? Is there some kind of calculator? Concerned about pulling too much water out of my well

Yup, there's a formula for that, lol

18' circle with a 15' square in the middle will get you the area. Multiply by depth gives you the volume in cubic feet. Use feet for all numbers. Multiply by 7.5 to get gallons.

OR cheat and use PoolMath....

About 330 gallons per inch of depth

1300 gallons for 4" of water
 
It's hard to say. Do you have any idea how much iron is in your water? Have you ever had it tested?
Do you have rust stains on your fixtures in the house?
You could take a sample from your kitchen tap and take it to the pool store for them to analyze. When they hand you the print out say thank you and walk out.
 
There are some youtube videos of people running water thru a 5 gallon bucket filled with poly fill that they claim work well for iron removal.

I just recently topped of ,y inital fill with about 18" of city water and the pool water went quite brown (after checking the city had a water main bust overnight and I started the fill first thing the next morning before they had everything flushed apparently). I sampled the iron (actual ferrover spectrometer test) and to my surprise it was only 1.0 ppm iron. The sample bottle I took just had a slight yellow color and did not match at all what the full volume of water in the pool looked like. So, I would say that adding even a small amount well water with iron should be avoided if at all possible unless you try and take the iron out first as described above or some other method.

I was able to clear the water by running pump/sand filter 24/7 for about 5 days and adding some clarifier with frequent backwashes.
