low point drain leaks - options?

[prof_fate]

I drained my system last fall and got things back together yesterday and today.

The low point drain 'caps' are leaking...not much once I added teflon tape and gorilla torque...but still a drop here and there when under 55psi city pressure.

Anyone got a solution? Would gluing valves on there be a good option? No more caps!

Heck, my ball valves are leaking a drop or two... Have been since I lost the caps when I did something at the end of last season. So far, I've lived with it...

Really need to take them off, rewrap tape on them and put them back on.

Did you loose the gaskets?

Is this what u have ?

Close - those caps match the fresh water tank drain.

My caps are gray plastic and hex in shape so you can put a wrench or socket on them (which I did...no, nothing is cracked!)

No gaskets, before or after my meddling with things. The threads I would think are pipe threads - tapered - so wrapped some teflon tape and its a lot better, but still dripping.

I don't think a hose type gasket would fit in the cap. Pipe dope would do it, but i've always had to use heat to get that apart and everything's plastic.

Go to lowes or hd and buy 2 1/2inch pvc ball valves. Use a lot of teflon tape and srew them on. This fixed my leak problem.

I don't have a guage on the system but 3 years ago they put in a new water tank in town and came and measured pressure. 40 to 60 is normal, we measured 55.

A friend in the city had over 75 on his house and installed a regulator to keep from blowing up garden hoses.

What is normal house water pressure

That's what I was thinking. I've had great luck with ball valves on my house plumbing.

Good to know it should work!
