Hi folks. I've done a fair amount of searching and can't find a solution. I have a steady, dripping water leak under my sink, WAY in the back, and it appears that is coming from the point where a black 3/4" plastic pipe joins an "L" shaped corner fixture. The black plastic has what I believe is called a crimp lock on it.
How does one go about fixing this?

How about replacing it with an automotive-style hose clamp.

Won't work - the screw type clamps are not strong enough. What you have is a PEX connector.

Follow this link to leaqrn all about PEX plumbing http://www.zurn.com/operations/pexrh...sApplGuide.pdf

Follow this link to see an excellent discussion about RV plumbing connectors. Pex Plumbing

Good Luck.

Try it Doggie, they put put those plastic crimp lock on for mass production, much faster and cheaper than a steel screw on clamp. I don't have those plastic clamps so of course I use the typical "radiator hose clamps". Thats what your city water and sprinkler lines are put together with and they carry as much or more pressure than your pump will put out. If you're hooked to city water, you probably have a pressure reducer as it goes in your city water connection anyway. It'll work!
Sry to disagree with you Doc

Doggie,

It happened to me in one of my old trailers. You have to cut out the complete connection/"L" shaped corner fixture and install some of the screw on connections/fixtures. You can not get that clip off then on again.

Thanks John. That makes sense. Now if I can only grow 4' long arms or shrink down to about 6" tall.

It has nothing to do with water pressure or how easy it is to assemble. (if that we're so, they would be on cars too) It's the type of tubing and how the fittings are made to work with the tubing. If a hose clamps happens to work, it will be temporary.

You wouldn't use the clamp type rings on an automotive hose so it only makes sence not use use an automotive clamp on this stuff. Get the right tool and the right replacement clamp and seal the leak correctly.

Well, as much as these connections sound like PEX, I am being told that they didn't even make them in 1980, the year my Foretravel was built. I went to Home Depot and bought a pipe cutter, some pipe and some fittings. I'll let evyone know if it works.

Nexxxt doggie. I went to Home Depot and got a very knowledgeable young lady to show me what I needed and how it works. I bought a
BrassCraft Ratcheting PVC Cutter, some 1/2" flexible pipe, a Qest elbow and several Qest coupling assemblies so if the need arrises
again I will be prepared. It wasn't easy working way back under the sink, but the price was right and the leak is fixed.
Happy Holidays to all,
Doggie

And since it was done right, you won't have to worry about it again.
