OT leak on 1" plastic

merlynr · Apr 29, 2015

Had a wet spot on the line going to the barn from the house and dug it up yesterday. I had the water shut off for a while so it wasn't all muddy but what I found was a leak at a joint with double barb connection. I tried tightening the stainless clamps and on the one side that leaked it made it worse. That tells me something is cracked and I suspect the barb fitting inside the pipe. It's going to take a lot more digging to be able to disconnect and repair. Is there something else out there to make this repair easier? Put water line in about 30 yrs ago and didn't even remember the joint I put in. The plastic line is that black pipe that came in rolls.

merlynr, get you a couple 1 inch slip couplings you want have to dig out so much.

For black plastic?????????

ditchwitch · Apr 29, 2015

yea after i saw that it was kinda to late , i just saw the plastic

Go to desperate depot and pick up some of the shark fittings. Cut the black hose and you will need a replacement piece, but they just push together. Likity split!

Try coming off the barb coupling and adapting to PVC and then a slip coupling will work. Just have a short piece of PVC in the ground. The slip
coupling saves a lot of digging. Tommy

What I have done in the past with that stuff was put some silicone sealer on the coupler then slide it in and clamp it down and let sit a couple hours before turning the water back on. My well pump hangs on that stuff and I have it going into my house also

Merlyn,

I buried black plastic pipe about 12 years ago to run a long water line. I had to connect the ends of two different rolls of pipe. The supplier
where I bought the pipe had some "compression" fittings for that purpose. The have two large nuts (one on each end of the fitting). The nuts
are slipped onto the ends of the pipe, then the two pipe ends are pushed into the fitting, then the two nuts are tightened onto the fitting.
There are some compression "washers" inside the fitting that are compressed onto the pipe when the nuts are tightened.

I believe that you could install one of these fittings without digging too much out of your trench. Just get the broken barb out of the ends of
pipe. Insure that the ends of the pipe are fairly square. Slip the nuts onto the end of the pipe. Push the ends of the pipe into the
compression fitting, and tighten the nuts.

It might work. Good luck.

When I put in my one inch line with rolled black plastic, I used CTS fittings. (Copper tubing size) It's a brass fitting, with a galvanized sleeve that slides into the end of the plastic pipe, up to a shouldered stop. No leaks and easy to use. Check compatibility, I think there are two different sizes of black plastic pipe.

have lot of that here
found that I had to double clamp both sides with the tightening screws opposite each other 180 degrees
or they will leak every time

I have lots of 1" black plastic buried and lots of connectors, I have always double clamped both sides, so far so good.
I also heat the pipe a bit with a torch when putting them together.

This is the kind I use in a transition between the black plastic and schedule 40 pvc. I've started using those on all of the joints I can't glue for one reason or another, too. You have to get them at plumbing supply. I haven't seen them at the Depot or anything.

If it's the poly pipe like used in sprinkler systems, they make a telescoping repair coupling. Check with a sprinkler supply co. We used
them all the time and you only need about 1 foot clear to install them.

My friend came over yesterday and we dug it back some and with the help from a soldering torch we got the plastic barb out which was broken on one end. Also with the aid of the torch he got a galvanized barb fitting in place with the help of some pipe dope and two clamps on each side it is fixed!

1130Leo · Apr 30, 2015

A torch does wonders on that stuff! Glad to hear you have the leak fixed!

Ozlander · Apr 30, 2015

Yeah, that's the way to do it , instead of try this, try that.

VaTom · Apr 30, 2015

Just think how much fun you would have missed if you had used that steel fitting originally, instead of plastic... I learned the same way.

RodinNS · Apr 30, 2015

I would be inclined to just put in a loop of 5' or so of new pipe... cut the old line just beyond the fittings, remove, then install the loop and make the reconnection with STAINLESS fittings and clamps. Galvanised or zinc plating doesn't cut it around here. Grey PVC is better than coated steel but not as good as stainless. Sometimes paying a bit more is a lot cheaper..

Everyone has some great ideas that will work. I love it when people come up with different way to accomplish the same thing. Like they say "there's more than one way to skin a cat".
