I replaced my ancient leaking outdoor hose faucet with one of these: [url]https://www.markssupply.ca/2323893/Product/390-120_Wall_Hydrants_-_Sediment_Faucets[/url] It's threaded. It requires this adapter: [url]https://www.shoptoit.ca/brand-brasscraft-ltd/bar-stock-adapter-12-inch/62020870/[/url] ...in order to connect to the 1/2" copper line. I'm happy that all the soldering connections I had to make are not leaking. However, there is a leak where the threaded end of the adapter meets the threaded portion of the wall hydrant. I used plumbers' tape on the threads. I wrapped it around 5 or 6 times, is that not enough? I think the hydrant/faucet is screwed into the adapter as much as possible. When I saw it was leaking, I spread vaseline on top of the tape after getting advice that it does the same thing as tape - creates a seal so water won't leak out. But water is still leaking out. The vaseline didn't make any difference. Depending on how much I open the valve, a few drops a minute come out, or a drop every 2 seconds if I open it up more. That's too much. I don't want any leaks at all, so what is the solution for this type of adapter where plumbers' tape is supposed to prevent leaks, but doesn't?

I have one of these [url]https://www.maidmist.com/automatic-air-valves/no-67/[/url] I think it's similar to a radiator vent which you're supposed to open up once a year to let pressure out. I didn't notice it before so I haven't been doing that. It's leaking. Was I supposed to have been opening it up once a year? Does it need to be replaced, or is there something you do to get it to stop leaking? Assuming this product is no longer available, what do I replace it with?
