Definitive Instructions - How to Avoid Damage to Your Fiberglass Swimming Pool

Fiberglass Swimming Pools rarely pop-up out of the ground. This is really an 'old wives tale' that can only happen in rare instances, and is always due to the owner's lack of knowledge about the pool.

That is not to say that damage never occurs. But the damage has nothing to do with popping out of the ground. The damage, about 98% of the time, is excessive ground water that has not been dealt with by the pool owner.

Here is the bottom line: Never, ever, empty the pool without first learning how. It's really very simple. The following applies to every swimming pool located in North America and the Caribbean. Follow this in the order shown.

"Everyone">Everyone

1. Buy a 2 1/4" saw bit that is marked BI-METAL, this assumes you have a drill,
2. Empty the pool quickly, and be there when the pool is empty,

A. The following is for swimming pools with a bottom drain. Pool owners without bottom drains, please skip to "B".

• Use a shop vac to quickly remove the water remaining on top of the bottom drain.
• Unscrew the cover screws, usually two, and again using the shop vac, remove the water that's still underneath.
• Search inside the drain pot for something that turns, a handle, lug nut, or a large nut of any kind. Immediately remove it. Most of the time water will come streaming into the pool, sometimes like a geyser, and sometimes nothing at at all. Either way there will be no damage to this pool.
• In the event there is nothing in the drain pot that turns, search for a short pipe sticking up. If this pipe exists, it is called a ''hydro static relief valve' and it will have a piece sticking up in the center of the pipe. This piece is usually stuck due to sand impeding its movement. If it doesn't move up and down, hit it a few times the the handle of a screwdrive until water comes into the pool, or, at least, it moves up and down.

• If the drain contains nothing that turns and has no hydro static relief valve, continue to "B".

B. This is for pools with no bottom drain.

• Use a shop vac to quickly remove the water remaining on top of the bottom drain.
• Using a drill with the 2 1/4" saw bit, cut a hole straight down, in the center of the pool, at the deepest point (usually about 2' or 3' away from the short back wall. It's easy to cut through because the bottom has the least fiberglass layers.
• After the hole is drilled, nothing short of a hurricane or earthquake will cause further damage.

  Finally, contact our company info@swimmingpoolresurfacing.com for a relief valve ($21.00 plus shipping) if you did drill a hole, but remember the hole must be exactly 2 1/4", which is somewhere between 55mm & 57mm. Both Lowe's and HomeDepot sell saw bits for around $14.95 (BI-METAL). Good luck with your pool.
