I just ran some of that polyethylene black pipe across my barn to add
a hose fitting in the back. This is not underground, I ran it up the
inside of the barn roof. This is in the cold north of the US and I
can not connect this permanently or it will freeze. Since I followed
the inside of the gable roof, it will drain out on both ends, since I
intend to only connect this (via a small hose) to the water hydrant,
when I need to fill the livestock tank in the back of the barn. I
have been dragging out (of the house) 75 feet of garden hose in
freezing weather, every other day, for years. It's getting real
tiring. With this setup, I only need to attach the short hose to the
hydrant (water source), and put an 8 foot hose on the back to the
stock tank. The short hoses I can hang right in the barn and they
Anyhow, I put in about 70 feet of polyethylene pipe yesterday. There
are 4 elbows, and the end pieces with threads to which I attached
garden hose connectors. The problem is that every joint is leaking.
I recall some years ago, I did some underground piping, and had this
same problem. I solved the problem by throwing the gray plastic
fittings in the garbage and buying costly brass ones. I could do the
same thing, but I have to drive to the nearest large city (60 miles
away), and then spend a fortune.
I should have never bought these plastic barbed fittings. In fact I
wonder why they sell them because they do not seal. I heated the pipe
until it was soft, and double clamped it. I tightened the hose clamps
well. I have taken apart the fittings several times, and reheated the
pipe, heated the clamps, and eventually I stripped out at least 6
clamps by using a ratchet and tightening so well that the clamps
stripped. Short of buying the brass fittings, and starting over, has
anyone ever found a sealer that can be applied to the barbs to seal
the fitting? I'm thinking silicone, which seems to seal most
anything, but I doubt it will adhere to the polyethylene, or maybe
even the fitting. Has anyone found a solution to this, or a sealer?
As a footnote, I will NEVER buy these plastic fittings again......
