LONG Water Line Question

[txdon]

3rrl, good idea and they are part of the assembly under the box. (see attachment) The brass/stainless steel is the better shutoff and I might replace them later. there is also another cut-off at the house 10 feet away and at the barn so the PVC usually aways stay open.

The bad news: I now have another leak.

The good news: it is small, and I know where it is.

You were right Eddie those unions are cr$%p.

I went to the local Ace Hardware store and got a different type of union that all the people around here use because they work so good and are easy to install. It is PVC but there are no threads to tighten to hold the connection like the one on there now. It can expand and contract so the glued connections do not break.

I will find out tomorrow if it works.

Jim I did not see your post earlier. Lesson learned. When I connected the backhoe I told Karen that I am either going to find the leak or make one. Since I would have had to go to the store either way I took the chance. The big lesson I learned is if I don't have repair materials on hand do not work past 4 P.M. I could have saved about 40 miles of driving and would not have had to work in the dark.

Eddie,

You make a good point regarding PVC valves. Initially I used brass valves exclusively, however due to the amount of hydrogen sulfide in the water, it quickly destroyed them. Thus I went to PVC. Yet, SS may be the way to go for future installations.

I think you are thinking polyethelene pipe in rolls that is what we used at my last cabin we used 400' rolls down the mountin from spring and just put rocks over it so hoof's woulden't cut it.

We had over 65psi at cabin so it was aboit 120' feet up to the spring with a 250 gallon oil tank there but we had over 1200 feet of pipe to spring and we let it run all winter to prevent it from freezing. tried all different connectors the wite nylon didnt hold up to the presure the grey plastic ones did work though.

this is the pipe we used fuseing it would have been nice but the tools werent available 30 years ago.

is that the black plasic pipe that comes in rolls? the rumor around here is, folks quit using it because it would develop pin holes in it, because of the soil type??? never had it happen to me, but i used glue type pvc to run the @1000 ft of line i installed in 1986..so far so good..

What I've discovered over time in my area (just a short drive from Don) is that the brass ball valves corrode to uselessness in just a few years ... but I've got 1- 3/4" pvc valve that has been in the ground for over 20 years and it still works just fine. Surprised me! I have a 4" piece over it sticking straight up so I can put a T wrench down it to turn the valve. I like the brass ones better myself - but not on/in the ground around here.

at work the pipe fitter uses hayward valves for all the plastic most of the time the true uinon type.

most expensive

less expensive type

some have been in plant with the chemicals (slight acidic) and still working fine for 20 years

Get rid of them??? The (stupid) cows eat them. They have beautiful yellow and orange flowers in the spring. What is there not to love about them? /forums/images/graemlins/smile.gif

tommu56, thanks for the links on the heavy duty plastic valves.

Here is a picture 2 days after installing a compression screw type 2" union on a long line. There was absolutely no leak the first day.

The local Ace Hardware Man recommended this type of union. As you can tell by the picture it expands. I put a double female on the male end to prepare for the patch.

Two things here made the job easier. A hole I dug on the right side of the repair to drain the water when I re-cut the pipe and a 2" PVC pipe cutter.
