There are two parts to a vinyl liner pool: the bottom and the walls. The walls are the first 3 1/2' down from the top, all the way around the pool. There are many different types of walls including galvanized steel, aluminum, fiberglass, polymer and concrete.

The bottom, everything below the first 3 1/2' down, can be made from cement, a cement/vermiculite mix, a sand/vermiculite mix, a cement/sand/vermiculite mix, or just plain sand. What is used under the pool liner depends upon the preference of the pool builder and the specifications of the homeowner or contractor.

How much does it cost to install a vinyl swimming pool versus fiberglass pool?

Well first of all there is no such thing as a fiberglass pool. You can have fiberglass walls instead of steel but your pool is still vinyl because you need a liner. These are the usual combinations of inground pools. Sand floor, steel walls, vinyl liner Sand floor, fiberglass walls, vinyl liner Vermiculite floor, steel walls, vinyl liner Vermiculite floor, fiberglass walls, vinyl liner Concrete floor, steel walls, vinyl liner Concrete floor, fiberglass walls, vinyl liner Concrete floor, concrete walls, no liner Concrete pools have to be painted with epoxy paint or if you want tile installed then usually you plaster over the concrete. Now a days 3 and 4 are the most common inground installs. 1 and 2 are usually pools that are 30 + years old although you can still have them done that way.

Water behind vinyl liner inground pool?

If you have water behind your vinyl in ground pool liner, you should first lower the water in the pool to normal levels if it is over-filled. Make sure that the vacuum pipe is clear, unclog it if it is not. Once it is unblocked let the water from behind the liner flow out.


I noticed a circular hole approximately 1 inch in diameter in my inground pool vinyl liner that was not there yesterday. What caused it and how can I repair it?

Vinyl liner pools normally develop holes from some type of abuse, usually something is poked, jabbed, stepped on or scraped causing a hole. On rare occasions a seam can split open. Chemical abuse is another cause. To repair, YOU may try a vinyl liner repair kit from your local pool store or YOU may call a swimming pool leak detection company in your area.

Should you replace your 25-year-old inground pool vinyl liner if it is wrinkling or should you wait until it leaks?

I think it is a judgment call. I would not replace it until it leaks. On the other hand, it will probably fail during the swimming season. Consult your swimming pool profesional for a second and perhaps more reliable opinion.
