The days of copper and solder are numbered, but since they still sell oakum and lead bars, that may be a while!

The only problem I find with a push on fitting is it will want to rotate easily. That can be a little disconcerting to someone trying to shut down a right angle stop that has that sort of connection. However, they don't get used much that way, just sitting there being forever open.

I have never had a leak with one; the seal is as good as the o-ring, so de-burr well if you cut tubing with a saw (highly NOT recommended). I'd also think the copper tubing would need to be not dirty or distorted. Throw away your torch!

edit: can't spell to save my life.

Thanks, I'll hold on to my torch.

Push on connectors have their place... (not sure what that is...but they have it).

Solder connectors are much cheaper, and they more solid - both mechanically and water tight. I'm not going to put a push on connector in a wall and close it up.

I think you will see copper slowly go away in general plumbing. It will still be used for high temp, and refrigeration and such - but unless the cost comes down, I think it will be replaced by CPVC and PEX in residential use. Until that happens, I'm using soldered fittings.

The fittings are called SharkBite . I have never had a problem with them or saw and leak.

Anytime I replace a water heater that is hard lined with CPVC, Copper or PEX. I install it using SharkBite Flexible Water Heater Connectors. I will even use them on new installations. Makes the next water heater swap a breeze.

Thanks everyone !!!
