Hi all,
I'm trying to come up with a way to winterize my main drain. Long story short, we can't air lock the typical way. Last year, I was brushing the pool and bumped the main drain. This caused a leak. It was determined that the wrong screws were used for the Hayward main drain. I was able to get the correct screws and this fixed the leak. Then we paid for a company to close the pool a couple months later. They used an air compressor to blow out the main drain line. This caused the leak to occur again in the same spot and we were losing 4" a day. We couldn't get the leak fixed properly as it appears the gasket is shot, so we had to temporarily fix the leak with a sealant. The sealant has held up for the past year. We'll eventually get a new liner put in and have the main drain properly installed.
My plan was to use a shop vac to lightly blow out the line, but I'm expecting this won't work all too well as it's not strong enough. I also don't want it to be too strong and cause a leak again. Then I was planning to plug the main drain line with a rubber plug and dump a few gallons of anti freeze in the line.
Any better Ideas? I'm aware that repairing the main drain properly so that the line can be properly cleared would be ideal, but it's not going to happen this year.
Thanks in advance.
