Has anyone had problems with push type fittings (any brand like shark bite, etc.) leaking when the boiler cools down such as when shutting it down for the season?
-
easy together = easy apart ...uponor ! :)
-
Mentioned shark bite fittings to my portage and main dealer and he wasn't recommending them.
Said they tend to leak.
-
With a push-to-connect, if you remove a connection you typically have to cut back a few inches to get to fresh pipe for the re-connect to onto. I at least think that is the preferred method
BTW, I agree with atvalaska -> UPONOR ;)

From what has been mentioned here over the years, Sharkbite brand are pretty good but most others leak. Watts brand push fittings seem to be about the worst.
I have heard that Copperhead brand are good too but I don't use any push fittings.
-
can't remember the brand they were, but I tried a couple on my initial setup and they leaked pretty soon. Took them out and replaced with clamps, no problem since.

Thanks everyone for the input. My Portage and Main dealer recommends and uses compression fittings but a friend from church uses and recommends the crimp ring style. I am wondering if any certain type has more flow restriction than another style as the least restrictive would seem to be the best to me (assuming no leaks of course).

Easiest way to tell would be to take the various styles/brands and measure the ID of them , the smaller the ID the more restriction. Of course though, being only and inch or so, the water will just temporarily speed up thru the smaller section, so unless you have an obscene amount of connections in your pex a few thousands between different style/brand fitting shouldn’t add up to a whole lot. On one of my circuits I have a total of four connections on the Logtor then it goes to copper with long radius elbows, when I’m done the house circuit will also be all copper with long radius elbows.

Thanks mlappin.

The crimp fittings are all fairly close to the same inside. The straight adapters are equivalent to about a foot of pex and the elbows are equivalent to 10' of pex.
If you use the expansion type they are larger inside. You are supposed to only use them on pex A.
I have seen them on pex B and pex C and they worked fine but I would stay with approved fittings for the type pex you are using.
-
I agree with staying with the correct pex crimp for my pipe. I was looking at using the crimp to sweat adapters with long radius elbows for best flow because the crimp elbows look like they would restrict flow more.
-
Sioux Chief makes a long radius pex crimp elbow but I am not sure where you can buy them. Menards might be able to special order them. I should ask next time I am there.
