2 Signs Your Swimming Pool's Lining Has A Hole In It

by Grace Motley

When you consider the interior of your home's swimming pool, you may not realize that there is a plastic or vinyl liner that coats the inside walls and floor to help protect the pool's structural integrity as well as prevent leaks. If this liner gets a hole in it or rips, it could cause deterioration of the pool and flooding of your property. While it can be difficult to see the damage under the water, there are a couple of signs for which you can look when determining whether the liner has a hole in it.

1.  Pool Water's Chemical Mixture Is Off-balance

One sign that your swimming pool's liner may have a hole in it is when you start noticing that the chemical mixtures are off-balance when you test for them and the pH levels of the water. Normally, when there is no water leakage from a hole, the water level remains fairly consistent, allowing the proper proportions of chemicals to remain steady.

However, if there is a leak because of liner damage, the chemicals can become concentrated. Or, if you notice that the water levels are going down and start adding water, the chemicals will become diluted.

Either way, the off-balance chemicals can cause issues, such as burning your skin from high concentrations or increased algae growth from dilution.

2.  Bubbles Form Inside the Liner on the Sides of the Pool

Another sign that you have a damaged pool liner is when you start noticing bubbles forming on the interior surface. If there is a rip or hole, the water from the pool will go underneath the liner. Or, air may become trapped.

If bubbles are forming, there is increased pressure pushing up on the liner. As the water or air buildup becomes greater, this pressure will continue to increase. If allowed to do so, the bubbles will grow, and there will most likely be more damage to the liner as it lifts away from the walls of the pool.

If bubbles are forming on the inside of the liner because water and air are getting underneath and the pool's water quality is adversely affected, you may need to have the liner either repaired or replaced. Contact a contractor who offers pool repair services to have them inspect the liner, locate the damaged area and tell you whether they can fix the damage or the liner should be replaced with a new one.
