Cpvc female adapter w/ o-ring


I'm in the middle of redoing my guest bath and am into the plumbing. I have installed a new shower valve with 4 male 1/2" pipe outlets (hot, cold, shower, bath). To plumb in the hot and cold I used cpvc female adapters with the o-rings. When I tighten them down as snug as I would expect it I appear to bulge the o-ring. It is leak free but i worry about the flow (takes roughly 8 to 10 seconds to fill a gallon bucket). Are these o-rings supposed to bulge? Does my flow sound restricted?

Thanks in advance for any and all help.

Chris

I've never heard of CPVC fittings with O rings, how about a picture.
Should have been glued fittings.

I think what you are talking about is there is a bib washer in the female adapter.

First off all you DO NOT want to make a connection like this inside a wall. It needs to be a solid connection.

Either a sweated joint, a shark bite connector but not what you are wanting to do.

Here is what I used...

I saw the other female adapter version (linked above) and in fact used the other version on my kitchen remodel. Not really sure why I grabbed what I did?

Is the one in my link not code for behind wall or is that more a personal sentiment?

The one linked above will be better than the one you have.

I don't think PVC/CPVC female adapters are code legal. In any case, I sould never use one inside a wall.

I'm pretty sure that's why they're illegal.

Threw me off when the OP said o ring, it's a flat washer.

Correct, it's a flat washer not an o-ring. Think I'll go the shark bite route.
