I have rebuilt my plumbing system on IP35-165 and I am looking at these PVC fittings into the Bronze 3-ways. They are very tight, and I used Teflon tape as well. My question is....
Should I also add a layer of 3M 4200 caulk or 3m 5200 around these joints? I do not ever want them to leak, and I do not plan to take this apart for years, so why not?
