I got an insect problem thus causing the dreaded pinhole leaks. The pool company (with leak detection equipment) found one in 2009 and patched it.

They were back at my house 3 weeks ago and found another pinhole and patched it. He did not think it was insects due to there only being one (at that time)

I noticed this week I have lost about an inch of water. I vacuumed the pool today and noticed 4 spots where the "dirt" reappeared after I vacuumed it. I get the goggles and go underwater, brushed the dirt away and I can see the little hole and the dirt coming back in to the pool.

All the leaks are around the edge in one area. There are now 6 (two liner colored patches and 4 clear ones)

I patched them up with clear patches and marked the skimmer to see if I got all of the leaks.

I do live in a high subterranian termite zone. My house has been treated / protected. I suspect that is what is causing the leaks. If I continue with leaks for the rest of the season, I am going to have the liner replaced in the spring.

Besides having the bottom of the pool re-treated by the pesticide company, are there any barriers that can be placed on the bottom of the pool that will work to prevent insect damage?

Thanks
