Covina, CA Pool Liner Tears from Sun Rot

Swimming Pool Inspection Services was called out to inspect a torn swimming pool liner in Covina, CA to determine what caused this tear, and what could be done to fix it. Our inspector found that the liner had “sun rot,” which can happen to vinyl liners through normal wear and tear. 

As part of the inspection, our inspector visited the property and spoke with the homeowner who said she personally maintained the swimming pool, but that something had fallen into the pool. She was not able to identify what had fallen into the pool. She stated that the liner was five years old.

Covina, CA Pool Inspection and Observations

A thorough assessment of the swimming pool was performed and the following observations were made:

• The water was cloudy.
• The vinyl liner was soft to the touch.
• There were no foreign objects in the pool.
• There was a correct amount of water in the pool.
• There was brown coloring on either end of the liner tear.
• The liner tore in a straight line.
• The tear is only above the water.

In addition, the water was tested and the pH level was found to be appropriate. Our inspector noted that this type of liner usually lasts 7-10 years.

Cause of Sun Rot in Covina, CA Pool

In his report, our inspector stated that the vinyl liner appeared well taken care of, and showed no signs of abuse. Abuse of a liner would include keeping the water level too low, potentially causing shrinkage, or having an improper pH balance in the water. None of these circumstances were present.

Our inspector determined that the tear to the pool liner was caused by “sun rot,” which is a condition that occurs in vinyl swimming pool liners over a period of years. Vinyl liners that are manufactured today are made with ingredients that prevent sun rot.  He stated that this was considered normal wear and tear, and was not the fault of the homeowner.

Our inspector recommended that this liner needed to be completely replaced. He stated that if the tear hadn’t been in the corner it might have been able to be temporarily patched; however, using glue on that tear would only further damage the liner, and would offer at best only a temporary solution.
