air in return jets and my ordeal

[sunofthebeach]

The first year when the pool company opened my pool, they put something on the plastic plugs before they screwed them into the pump. It was thick like caulk and dried into a hard rubber glob. at the end of the season when I unscrewed the plugs the I could just pull the glob of stuff off.

any Idea what they put on the plugs?

My guess is silicone seal. Forms a good thread seal and can be peeled off like you said.

Plumbers putty.

I'm with Isshin on this. I use silicone grease on my o-rings and plugs at the end of the season and they don't get that plug. But the plumber's liquid on the solar panel connections does.

I started thinking about it and it's called plumber's dope. Plumbers putty is the stuff they use to mount sinks and stuff.

I had air for a year and it ended up being a brass anchor from my winter cover lodged in the suction line where it made a 90 degree bend.

By the way, I had to cut a 1ft square dig down to the elbow cut the line to remove it.
