Fiberglass Pool Install

Water chemistry question... The PB is pouring the concrete collar and leaving the job site until spring. The pool has the water in it that was trucked in and it has since turned dark and green. The pool is uncovered and the bilge water frozen on top. There are no chemicals in the pool.

Is this normal?

I though Leisure Pools USA required that the water be tested and maintained weekly (at least during non-covered season) in order for the gel coat warranty to be honored. I read that unattended water can cause issues with the gel coat. ??? Lost.
What assurance do you have the PB will ever return? Do you have any financial leverage at all this point?

Okay, more bad news...

We have had unusually warm weather, so I took the opportunity to go out and clean up and inspect the pool-install-in-progress. They poured the concrete collar a few days before Christmas, and aren't returning until the spring, when it gets opened for the first time (it was not opened yet, so no water in pipes, or even electrical hooked up yet).

Previously I had posted concerns when they placed the pool in the wrong spot and rather than lifting it, opening the hole, preparing a proper/wider base, and reinstalling, they just dug a wider trench and dragged the pool sideways by 18"-24". My concern was the combination of a lack of a proper gravel base and the fact that they mixed a lot of soil in the backfill. Well, today I went out and sure enough, the pool is grossly out-of-level on the width span (which is under 12').

I measured a 1.25-1.5" difference from water level to top of shell in the 11'10" width. It is visibly not level, and a level confirms it's out. It looks worse than when they first installed it, which leads me to suspect that it has settled in just this short period due to improper base and clean backfill.

The guys at River Pools (Jason Hughes) say that it should be (all around) within a half inch.

Any help would be appreciated.

Let’s see if anyone has experience with this type of situation. My guess is you need to remove the pool and start over. I don’t know how you can get the tub level and stable with the concrete collar on it.

You need to decide if you can live with the out of level pool and see how long it lasts. I would be worried about PVC pipes cracking if the shell moves too much.

The PB just said he doesn't trust my tape measure and that it was within a 1/4" all around at collar pour. He is coming out to use his laser level.

He is going to have to take off the collar, pull the pool back out (hoping the damage is not done aka cracking already started) and star all over with the hole. They should have NEVER drugged it to put it in the now spot. The bottom was not prepared properly or all for that matter.

Let me guess. the high side is on the side the drug it to.

Time to make sure EVERYTHING is in writing and have your own person out there to check your PB's laser.

Make him use a crane this time. I believe it cost about $400 to rent the crane when we were installing our pool initially, but it isn't so much that he can't absorb it, IMO.

Sorry to say, Kim is correct (not sorry that she is right, but sorry that you have to do what she says). Lift, regrade, set, check level, pull again etc.... There are really no shortcuts on this part. Fiberglass pools are 99.999% about the installer. A great pool with a crummy install is worse than a crummy pool with a great install (more or less).

Jason is right. - .5" is pretty good, I think RPS got closer than that on mine.

Will be interesting to see the installer and their laser level.

You would be lucky if this guy comes back. I haven't rly commented in this thread but it's painful to see what this guy has done with this install.
Fiberglass pools are an art to install unless they are flat bottom. The only way to be sure of install is to use graded 3/8 gravel and compact the heck out of it. Screed rails should be used that are shot with a transit.
Also know that no fiberglass pool is dead level. The shell itself is +/- a half inch from the factory. That is the acceptable range for an installed shell.
At this point you have no leverage. Not sure why this guy is paid in full without being close to done. If he was only going as far as collar he should still not be 100% paid. Theres always punchlist items on any build and they get completed and signed off THEN final payment is made.

Guys like this give the bizness a bad name. The real problem is the hack installers. 99% of customers dont care what's going on thru the build. They see a pool when it's done and looks good and new and would never ceck level or look further than a whole pool picture. I would let him do whatever to check with a laser and go from there. There is a mouldings or even tile you can apply to waterline to cheat the eye and then mud heavy on coping to compensate to make it look good if the level is gonna keep you up at night. Theres no way hes gonna reset that pool. That would require busting the collar and digging out the pool and its plumbing. It's as much work as putting one in from scratch and a half install on top. Chances are the shell would get damaged. I would reach out to mfgr. and see if you can get them to put pressure. I'm unsure if they gave you this installer or you found him and went with that brand based on his relationship with them. I wish you luck and a better outcome. Like I said it is fixable to look good with options

I would stop and take a deep breath. You have fill and other construction problems, I get that. But what I have been told is that the remedy for a fiberglass pool that is ends up out of level is to install waterline tile parallel to the waterline, then pour a deck level too, so you never see the top piece that’s not level.

I also would not take a great deal of care listening to what River Pools tells you. Just my view.
