Another pex question

1300 miles from home, the plastic Tee coming off of the water heater cracked, and my Pex fittings, clamps, and crimping tool are all back home in the big camper. I know, I know, rookie mistake. Went to the only "RV parts store" around and they have nothing. SO, will a Sharkbite Tee work? I have never used Sharkbite fittings so I have no idea. Are they easily removable?
If not, any suggestions for a quick fix?
TIA...

you should be able to go to any hardware / home center for PEX.

I never used sharkbite but most people seem to really like them

sharkbite in a pinch. it should be replaced properly as soon as possible. most hardware stores you can rent tools like a pex crimper and get some fittings and be done in an afternoon while at your destination.

Shark bite will get you home just fine. Or if you are near the ocean go to a marina store and get Whale brand fittings. Like shark bite but are easily removed

I’ve been slowly replacing the plastic PEX fittings with brass in my rig as needed or if I’m staring at it with nothing better to do.

And why do you think SharkBite should be replaced at all?
SharkBite fittings are rated for behind the wall usage and approved by plumbing code standards agencies.
I have replaced 90% of my RVs crappy banded connections over the years with SharkBite and have not had one leak or failure. Have used them in several barns and storage sheds.
They are a permanent solution.

Yes, they are easily removable. But why remove them?
Pay a few bucks for the pex cutter and reaming tool to ensure you have a good connection. Just follow the simple instructions.

Thanks to all for your replies.


Scott, the reason I asked about removing the Sharkbite is, the Pex tubing is not completely straight and smooth due to the previous Pex clamps holding it on the Tee. I thought if the Sharkbite needed to be installed on "virgin' tubing and wouldn't seal correctly I might have to remove it. Unfortunately, there is no "slack" or extra tubing so cutting any of the lines back is not an option.
Thanks again

I'm with Scott, no reason to remove any Sharkbite fitting.
They will last longer than the plastic junk from the factory.

And most Sharkbite fittings are bigger so if you cut the PEX right at the very end of the plastic tee, you "should" have just enough pipe to make a good connection.

More excellent info! Thanks for your reply.

In replacing my banded fittings with SharkBite I had the same problem for some of the connections. i cut back the pex and used a coupling to install a new section of pex to reach.

I replaced all of the PEX plastic fittings with Sharkbite fittings. Got them at the local Lowe's store. All problems are resolved for now and in the future. Those cheap clamp-on PEX fittings are mostly junk, but they are cheap! Why does one think the RV is full of them?

RV parts stores usually have nothing suitable.

Agreed, on all points. I was telling my neighbor about it today and he asked if the Tee froze and broke. it wasn't cold enough for it to freeze here last night, but it got me thinking... being on the hot water side I'm sure after 10 years of hot and cold it got brittle, which probably contributed to the crack, but when I get home I will be replacing all of the plastic junk on all the water lines.
Thanks for your input Bob.

I think it should be mentioned that “shark bite “ has become an eponym for any fitting of that type. I’m with you if you are using the original brand made with a metal body but beware there are cheap brands too. The cheapest of them rely on water pressure to keep them sealed by compression of the o ring. Then when you disconnect from water and the pressure goes away they will drip until the pice is empty or pressure is restored.

Just saying.

Good information, thanks MGD1961

I have made some Pex repairs with simple hose clamps like the good ones used on radiator hoses. The ones with slots. No need to buy a bunch of crimping tools. No need to miss your tools back home. Sharkbite clamps are for homeowners on a budget.

Seems to me most people would prefer to use proper tools and parts for the job. I’ve MacGyvered lots of stuff too but I don’t think that’s the point here.

Agreed and advising folks to use the improper clamps for PEX is an invitation for failure and not the advice one should expect on this (or any other) R/V forum.

As was mentioned earlier in this thread, SharkBite fittings are plumbing code approved, used by contractors everywhere and saying they are only for budget minded homeowner repairs is silly. BTW... have you purchased any SharkBite fittings? They are really not "budget friendly" but they work well and need no special tools/clamps.

I just installed these day before yesterday after replacing the kitchen faucet because a cheap plastic braided hose blew off th bottom of the faucet and flooded the kitchen island. I have no intentions of ever replacing the fittings with anything else.

Yes. You just need one of these removal tools.
