Tankless Hot Water Heater w/ Well water and pressure tank???

[JTW]

Some use Teflon tape, I’d use pipe dope for the best results. 45-50 is a good range for pressure.

I agree.. I’ve always preferred pipe dope. I’ll only use tape if it’s plastic.

So.. pipes dont need to be tight to seal? I tightened them all down hard. Like a young nun.

I’m with ya.. tighten until it starts to get that contact and then finish it with where your valve or fitting need to be.

If you get ‘em that tight, you stretch ‘em out and blow the back out.

So I wrapped the full threads. Not doing the starter threads may help make a better seal.

I'd say i did 6+ wraps. Had to pull a few off due to wrong direction but got them all correct.

I have pipe dope ready.

Six wraps seems like too much. It looks like you’re using the white stringy tape. That stuff is thin and not that great but you should be able to use it. I’d go 3 wraps maybe 4 but try to taper the layer of tape off the starter thread.
I think they’re trying to sell more tape than you need. Even blue monster says minimum of 3 wraps but it just gets pushed out of the joint. I’ll use a light two wraps and when you take it apart, you can see the tape on the threads still.

Humm...
I could be overtighten them and blowing the seal I guess.

But I like them tight.

When I’m doing boilers or water heaters, my old school journeyman I had 20years ago thought me witch seems the best way that I still do today on jobs. Everyone has there different ways keep in mind, but this has served me well in the trades. I use a standard Teflon tape and wrap the threads 3 times minimum how ever may times after is up you you but 3 is usually fine You’ll get a feel for it. Then I use The Green Stuff pipe dope one good swipe over that. Then just hand tighten down your pipe till it needs a pipe wrench or channel locks. Then a few turns till you feel your on the verge of possibly gona have to go Armstrong with it and stop. You’ll have a good deal that won’t green gobbler up in time and not damage your threads. It’s a lengthy explanation, once u do it it’s actually quick and easy. You can do this with plastic, copper or galvanized pipe. Hope this helps you.

Should look something like this when you are done.you can see that the threads are not buried.

Beautiful example. The copper females are easier to stretch out.
