Hello, I installed an auto chlorine feeder a couple of years ago and have since stopped using it. I had to drill two holes in the PVC pipes for the lines. Do they make any kind of patch or sealing plug to use to seal the hole. It is a hole just like one for a temp sensor. I have a lot of ideas in my head, but I was wondering if someone makes a piece to go under the clamp to seal it. Hate to reinvent the wheel.
