Water Cooler

I just ran a new copper line to the old swamp cooler and for some reason I can't stop it from dripping up at the flow valve. I have plumbers tape on the threads but I get drip, drip, drip...

Any secrets to using these compression fittings?

Perhaps I should buy a new float valve?

Compression fittings do not require teflon tape and in fact will inhibit a leak! Just the soft copper, nut, ferrule and fitting are all that is required.

I am not a big fan of compression fittings for that very reason and prefer John Guest fittings ... but if you must use them I found a light coating of teflon paste between the ferrule and tubing will do the trick

It's been a long time since I had a swamp cooler...
Your lucky they work in your climate...
To humid here...

But, I'm guessing that they have now gone to plastic similar to a Fluidmaster 400A and are using plastic at the attachment point...

A common problem for them is a crack on the shank where it mounts and the supply attaches...

If thats the case replace it.

John Guest fittings is what I was looking for but I didn't see them or sharkbites in a 1/4 size at *********.

The connection is copper to copper but I've had the float valve a few seasons.

I will try a little dope but somewhere back in my old mind it seems we used to flare or flange the end of the copper tubing a bit after we put on the nut and sleeve, then we would make the connection. I asked about such a tool at Home Depot and the kid how no idea what I was talking about. I guess they don't do it that way no more???

You talking 'bout one of these babies¿


Not needed with the compression joint you are making. Most times it's used for gas that's piped in copper.

Yep, went back to home depot and found a guy who instantly knew what I was talking about. He said the same as you. I don't need it.

The nice guy sold me a new flow valve, pipe cutter, compression fittings with sleeves, pipe dope and descaler. I think the first guy who didn't know anything was a lot cheaper to speak to but now I think I have a plan to keep that thing from leaking.
