Replaced the liner, question about the old one?

Could very well have been the cleaning. Leak started after the first year. The first year i hand vacuumed, often hitting the cove and running along the cove while cleaning. I usually vaced from one side and slid the vac over to the other until it hit the wall.

On my IG I had a few slits open up at the cove in the deep end a couple years ago. A real dog to find. Think it likewise could have been the vacuum brush maybe catching a sharp stone or something. Just a suspicion. No robotic. I usually only get fine dust or something like that in these areas so I vacuum the big stuff, bugs and the like, from the center and rigged the vacuum brush on the filter outlet to blow. I use that to kick up any dust and fine stuff into suspension then let the filter get it. Also great for blowing spots of algae which I soometimes get on the stairs and ladder rungs. With the volume of water coming out you never have to contact those areas with the brush.

Just another thought, but my neighbor had a similar issue, but when the diver came out he said ants had eaten the liner. I guess they are very tasty things for the ants.

Just a thought.
