Re: RTV for plumbing?
I like to use a teflon-containing thread sealant compound that is listed as "safe for plastic." Some of the older formulations contained solvents that could damage plastic.
In spite of that, I find that the quality of workmanship of plumbing fittings nowadays is somewhere below rock bottom. It's nearly impossible to get a good seal anymore. But then again, most of those fittings come from a large, communist country on the other side of the Pacific where the workers have no pride, the companies have no standards, and the government has no morals.
The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
