New Install off level

Postby Weet Pee » Tue 05 Jun, 2007 08:34

We just installed an above ground pool. It is a wood tongue and groove structure with (2) 1/16" thick stainless steel straps around the base (like a half whiskey barrel). We filled the pool yesterday and since then it has settled just over 1" off level. I am concerned about it collapsing since everything I read says "must be level". I have two small children. Will it be okay? and what really is the tolerance?

Is this a homemade pool?

I don't think being 1-inch off level will cause the pool to collapse, assuming you followed all the other instructions.

okay what about 1 1/2"? It settled another 1/2" by the second day, and has not moved now since Wednesday. What is the tolerance and are different structures more stable than others? Our wall thickness is about 1" as opposed to an aluminum or metal pool wall thickness? and does the law of physics to these round pool designs change with struture design?

New Install

Postby HydroForce2007 » Tue 12 Jun, 2007 22:19

Our yard is dippy, bumpy, grassy, with a slight downhill slope. We're trying to install a new HydroForce Fast Set Round Pool, 18' x 48". We've turned off the hose as the West-side has 8" of water, the East-side 4". I've been trying to get the water to run to the other side with layers of carpet under the low side, but the West-wall started to buckle. I guess we have to drain it and start over (it looked level until we started filling it with water). Should we use grassy pieces of sod to build up the West-slope or dig down into the dirt on the East-side? The water truck guy said it looks pretty level and would bounce into position once it's full, 5,500 gallons. I don't think so. He also said he just filled a leaning pool and when it hit the 7,000 gallon level, it collapsed. Please help, our 9 year old grandson is standing by with his goggles on and we're one day past his birthday already.

Folks the ground MUST be completely level or the pool will collapse may be not right away but trust me it will collapse. All round pools are constructed on a even level outward pressure to all sides as it fills, if one side gets 4" of water more the pressure will be alot more to that side.
Yes just level it with the sod from the high side. If the ground is hard to work with a sod cutter can be used to loosen it up or you can even bring in some topsoil and pack it. Hope this helps.

I understand that a fast set pool (water filled makes the sides go up) would collapse if the water level is off. But what about a hard sided pool, I know there is a tolerance. I just don't know what? Our walls are level all the way around, but the water looks and measures from the top rail to the water off level by 1 1/2" from one side to the other. We just can't figure it out. We are thinking of leaving it for the year and seeing what happens over the winter. If next year looks same or worse we may take it down then. We are a bit sick and tired of this pool at this point.

New Pool

Postby HydroForce2007 » Fri 15 Jun, 2007 16:04

Thank you, trapper. We've been putting sod under the West and softened the East with water (under the pool). As the West crept over the sod, the water slowly moved to the East. The water guy wanted to fill it, but I stopped him when the water level reached 2'4" - West, 2'4" - North, 2'2" - East and Yikes! 2'6" - South, especially when he asked if the pool was oval (because that's the shape it was taking).

Now we're waiting (hoping) the pool will level, but the oval shape is really bugging me. On the West and East the water is right on the inside bottom seam and the sides bulge out appropriately. On the South and North, the water has moved out the bottom of the pool 2 feet back, past the bottom seam and the walls stand 2 feet straight up. (It's a 4' high pool). The water measurement inside the pool, in the middle and all the way around is pretty level, 2'4". As the West is still creeping out, we keep adding sod (The liner has covered about 3' of extra sod already).

Is it safe to swim in the pool if we don't add any more water? Could it still collapse at this level? It's supposed to be 4' deep or 80% capacity, 3'2".

Next season, we're going to use sod and styrofoam insulation and level it first.

All pools must be level. 1/2-1" off is pretty much your limit to be sure everything is going to stay level and not cause any damage. Are you in areas where there is frost or clay? If so, you could have problems. I would say you really need level to within 1/4-3/4". Ground prep is the most important part of installing. I would be concerned if my pool was dropping 1/2" or more in a day or so. Did someone install this for you? (the wooden pool kit) If so, they need to fix it. If you installed it yourself, please watch closely - Level and compact are keys.
