It's an irrigation valve this time but same with garden faucets and stuff so it might be of interest to others here. I have a really hard time threading on PVC nipples, adapters, valves and whatnot without hearing that faint hiss when turning on the water. Then drip .... drip .... every ten seconds.
So far I've tried: Three layers of Teflon tape, Oatey Great White Pipe Joint Compound, Master Plumber TFE Paste. Nothing even comes close to the old hemp & paste method I grew up with, which never ever leaked. All this newfangled stuff always leaks. Grumble. Thing is, there comes a point where such a thread gets overtorqued and if I did that right now on our problem under the house I'd cause major grief because the contractors had joined all this stuff together without any pipe in between.
The old valve actually sat in there quite loosely and didn't leak. I could unscrew it by hand. They had used some really thick white gunk, not this runny "modern" stuff. What could it be? Any other options?
Regards, Joerg.
