First experience with Pex


So, had to replace a valve in my RV. Being relatively new, the rig is plumbed with Pex. First headache: find a replacement valve. Took a 40-mile drive to the nearest RV place for that as Home Depot doesn't seem to have them.

Second headache: Don't own a crimp tool. Was told hose clamps won't work. Ended up buying a pocket tool ($25.00) for making two crimps. Yet another tool that's good for absolutely nothing else, and a PITA to use as well.

An expensive fix to be sure, but at least I have hot water again. Say what you will about CPVC, but I'll take it any day.

Could have just bought a Shark Bite valve and needed no tools.
Pex is a perfect choice to plumb RV's.
It's not going to split the first time it freezes like CPVC would.

Should have bought Sharkbite brand valve. Home Depot specializes in them so I know they had it in stock. You can return the "pocket tool" for full credit if you bought it at Home Depot.

IMHO brittle CPVC would be among the WORST choices for use in an RV.

I did buy a Sharkbite valve - that's what the RV store had. If HD carries them, they must've been out of stock. As for the tool, whether they'd take it or not, I wouldn't feel right returning a used item for a refund.

Make sure you put the stiffeners in the pex both ends prior to using the sharkbyte.

If you use the stainless steel cinch rings instead of crimp rings, one tool will fit 3 sizes and cost a lot less than 3 crimp tools.

I agree with your earlier post, those things are a real PIA to use. I own one and use it occasionally when the work space is too limited to fit my normal crimp ring tool. Hate it but it does a good job.

Good point Ghostmaker. Many knock-off brands package the inserts loose or separately. Sharkbite fittings are sold with the inserts already installed and you actually should remove them prior to using them on copper, yet most users do not. So, no issue with making sure to insert the stiffeners.

My valve came with no stiffeners. Since the Pex slides over the "barbed" ends of the valve, why would I need them?

Shark bite ( brand ) with barbs, yes. How do you think the plumbing industry got so screwed up over the years.
