I had a little water leak at my cottage and had to change out some piping. I used some pex and sharkbites and they worked great. At least for keeping the water contained, which is probably 99% of good plumbing.

Anyway, I changed my old master shut off tap for my outside hose to a sharkbite ball valve. Again the tap works great but when you turn on the hose or pull on the hose, the bib rotates. I believe it is rotating on the sharkbite fitting inside the cottage. The sharkbite is biting down on 1/2 inch copper on both ends, with the end by the wall going through to the hose bib outside. This rotation is not creating a leak but I worry that with constant rotation, when it's used, that it might.

My question then is, do you think this rotation might create a problem in the future and if so does anyone have any ideas on how to stop it from rotating.

 

Push on fittings are designed to rotate. It might be irritating in your situation but there is no concern for leaks.
I would look at ways to secure the hose bib. Maybe some strapping inside or some type of minimal expansion foam. I don't see much siding in Southern Cal.

 

Use a valve with a mounting flange (sillcock).

 

That valve will work. Checking back, I found something interesting, a hose bib anchor. This one is a Pasco 5023:



I haven't used one but it looks like it could come in handy.

 

Nice find Brian. If you couldn't find one last resort you could make one with two metal corner angles and a couple of worm gear hose clamps.

 

Great ideas. I found this hand held shower head holder that seems to work for now. Almost looks like it was made for this specific purpose. It is just giving a tightness to the hose bid and seems to prevent it from turning when I turn the tap on. I doubt it would do much if someone pulled hard on the hose.

I am sure I could cut into the aluminum siding and fit it in tighter if the problem becomes more of an issue. I would have to silicone around it and of course I would have a new problem if I ever bought a hose of a larger diameter, so I probably won't do that. I could also create a sort of strain relief clamp below it to hold the hose to make sure the hose is always pulled in a downward direction as opposed to side to side. A new valve with the mounting flange is probably the better longer term solution, but do I really want to start doing it right the first time and forgetting about it, when I can just keep fixing one band aid solution after another and having all the fun with that. LOL.

Anyway, the sharkbites are not leaking and that is the main thing. Amazing little devices. Thanks for all your help.

 

Changing the bib would not be too difficult. The sharkbites can be released and reinstalled.
To release the fittings you need a removal tool or a small crescent wrench set to a little more than 5/8". You push in on the plastic ring firmly and pull the fitting off.

 

Very creative solution, but it looks like it will impede removal of the hose, and keeps the weight of the hose bib & hose on the pipe. It may also pull on the sharkbite inside.

Personally I like these fittings for hose bibs:



Solder a piece of 1/2' copper into it, drill a 1" hole (put some silicone caulk in it) then push it in and screw to the wall. It adds support similar to the hose bib ray2047 mentioned above.
