Sharkbite / Pex Plumbing (repair), pictures.

I'm working on yet another older RV that has the 3/8th inch gray plastic plumbing that was standard build in the 70's and 80's I'm assuming. Anyway, put water to this good old camper for the first time and had two plumbing leaks and dripping faucet. I don't own the crimping tool needed to repair the pipes, nor do know where to even get it.

Quick trip to my favorite hardware store, McLendons (they are the best, way better than any big box hardware store) and I'm set up with this material they call Sharkbite. How cool, it's the exact inside and outside diameter as what I have in my camper. And you just snap the fittings together.

I know modern homes use this now in 1/2 inch size instead of copper plumbing, but I just wanted to share that 3/8 inch works wonderful with older RV's.


This is what the pipe looks like. For residential use I think people use blue and red to signify hot and cold lines. It comes in 6' sticks or longer.


This picture shows what the old connection looks like (the gray end) and the new connection, Brass. The little orange c-tool is used to release the grip if you need to take apart the connection after you inserted the pipe into the brass. I thought once you plugged things together, that was it, no going back, but they easily come apart if you use that little tool.


My city water hookup (and back flow valve) were leaking where it connected to the gray pipe, so I replaced that entire section of pipe with the Sharkbite pipe and brass coupler. Super easy fix.


The cold water line to the faucet was leaking, and the plastic was cracked, so I cut it off close and installed the new Sharkbite brass coupler to the faucet and then inserted the original gray camper plumbing into it. Sealed tight as drum. I'm happy to put those plumbing issues behind.

And McLendons even had the entire valve assembly for the inside of the "Valley" brand kitchen faucet in the truck camper I'm fixing up, so the kitchen faucet doesn't drip any more. The old faucet was chrome plated brass, good quality, so I didn't want to replace it with a cheap RV plastic one or expensive residential. $16 for the new valve assembly.

Now I suppose some will tell me this is how they make RV's now with this stuff, but my 53 Angelus trailer, my 2003 Forest River and my 1987 Alpine all use different types of plumbing. Hans

    They now use PEX with compression fitings,, This is a lot less expensive than Sharkbite and they have the tool needed.

    But Sharkbite is the way to repair... So that's how I'd do my repairs as well.
  • I used these connections to install my water softener semi-permanently in my 5er basement. When I need to take out the softener (for winterizing or whatever) I simply take the connections apart and remove it. Works great and it is a wonderful alternative to purchasing pex clamps and tools.
  • They can be more money but well worth every penny in frustration saving when working in a tight spot. Using them under the vanity putting in a new sink the DW wanted in the rig saved our marriage...IYKWIM.
  • As a side note Both Sharkbite and Gatorbite have fittings that work with copper pipe as well. Sure makes it a lot easier than trying to solder pipe in a wall when remodeling or doing repair work.
  • JFYI that grey piping is PB which was banned in homes due to issues with deterioration especially from heat and chlorine back in the 1990's and is know for issues with leaking connections, etc. I would recommend replacing what you can including the fittings either wholesale or as you do repairs/upgrades. Also, I would make sure that you never leave the water system pressurized when unattended and having that piping would make me seriously consider NEVER hooking up to city water, but use the onboard water system and pump EXCLUSIVELY and again making sure I could really hear the water pump run/cycle and never even leave the pump on when not in actual use.

  • When our new Coachmen had a leaky valve on the road we used "gator bite" fittings from Lowes that are exactly the same but for the name.
    Pricey,but easy and quick.
  • If SharkBite fittings are not available when you need them, Watts, SeaTech, and GatorBite fittings are similar "push on" products that also install with no special tools.
  • SharkBite fittings are fantastic. I use them a lot, even on heating systems.
  • Thanks for posting, Hans. This may be good information for those with older plumbing.
