Skimmer hole on left side? Hayward SP1091WM

[JohnFoe]

I opened up the pool to start cleaning up the water.

No major leaks which is nice.

However I noticed a drip leak under the skimmer and there is a hole there as well.

I couldn't find an image anywhere that shows if this hole is intentional or what it is. I'm hoping that someone else knows if their skimmer has a hole like this. It is dripping water, not much to care, but maybe a half gallon a day which made the ground have a wet spot. I'm going to tighten some screws since I never have in 3 years on it and maybe that will stop the leak, but just seemed odd.

No, I’ve never seen that on a skimmer. Was it not there when you closed? Trying to think what could cause that type of hole.

To me it looks like the hole doesn't belong there as plastic seems melted through.

Yeah I looked back on some pictures and videos I took and none of them have that hole.

I am very baffled.

Yeah does have a clean cut / melt appearance. Nothing hot I know of has been there. Just wrenches and screw drivers when hooking it up.

Guess I need to fill the hole / patch it.

My best guess is a drop of muriatic acid. Not sure how, but that is my only logical thought. I don't remember the last time using it.

No way, it would have had to sit on one spot without water and even then I'm not convinced it'll burn a hole. You wouldn't have been at the skimmer when no water is present and MA in your hand. That looks like it was deliberately done somehow or maybe an air bubble in the plastic from the manufacturing process.

Air rifle?

 

[kellyfair]

It looks like it was somehow shaved off.

I'm trying to remember if there's a hollow cavity there that could hold water. If there is then freezing water is the likely winter culprit.

It's not from acid.

Probably impact from a small hard object like a BB or maybe a rock.

 

[JamesW]

Google bb hits glass for pictures and you will see the same type of impact pattern of the small center hole with a spread out crater.

My first thought as well.

Any lawn mowing going on yet there ? Coulda easily thrown a rock.

Yeah it is hollow it seems. It has no water in the winter, but if it was holding water in this hollow area it definitely could have frozen. Figure it might crack the plastic instead of making a hole, but if that is the weak spot it is possible.

All of the skimmer screws were tight so I didn't try to force them tighter. A gasket could be failing, but hard to know.

Last night I put clear packing tape over it and it stopped the leak, so it is very low pressure water. I'm going to look for "epoxy putty" today that works on ABS plastic to fill the hole.

 

[wireform]

I use This one from time to time for many years now and it never failed me.

 

[JamesW]

What's on the inside?

It seems like it should be leaking a lot with a hole like that.
