Running 150ft of water underground from one pole barn to another. Want to run the potable water line inside 2" conduit for easy replacement in case of a freeze issue. Are there any types of pipe that would flexible enough for this application? Would PEX-A be the best?

We have pulled 1" pex a through 2"conduit. Actually on Monday I'm gonna attempt the farthest run I've tried yet. We need to pull roughly 150'. I think we'll be able to do it but it's not easy.

If you only need a 3/4" line it should be very doable. Just make sure you use actual electrical conduit with the really long sweep fittings.

Thank you John.

I wanted to use 1 1/4" but 1" will work. Did you use PEX-A or PEX-B. A is supposed to be more flexible.

I saw that the min radius for 1" is 8" which is just about what a 2" Electrical PVC 90 is.

Just for reference Home Depot sells two rolls of PEX-A 1" 300 ft.



One is labeled "expansion pipe". Is there a difference? Does it matter which one I choose for the 150 ft run I need to do?

We don't typically use fittings in the conduit so that there is nothing to hang up on when pulling tubing through. But if you get pipe with bell ends on it, you can install them so the lip of the pipe is always in the same direction. We always run tracer wire with it too in order to make it findable without digging later. Make sure to run at least 1 extra pull cord through the conduit with the PEX.

Pretty sure the expansion pipe is pex a and the other is b. Apollo is the one I'd use.

Alot of the home depot/Lowes/ Menards sites have the pictures and the descriptions messed up. It's not a reliable way to pick materials.

Have the trench done and all pipes in the trench. Have strings pulled including one for the PEX pipe. My retired election friend was going to help.

Used 2" PVC with electrical sweeping 90's.

John can you elaborate on how you did the pull? Not sure how to attach the string to the end of the PEX pipe other than to drill small holes and pass the string through it.

There's a knot we use in piping to lift or pull pipe. I can't remember the name of it. You tie a knot and then loop it several times down the length of the pipe and tape it to the pipe. The more you pull the more the rope digs in and cinches tight. You actually don't need the tape but we use it anyway just in case. Sorry a can't be of more help than that.

Some sort of hitch I used a clove hitch with some variation (almost exclusively ) for picking pipe like cast iron with rope all my tag lines on 40 ft lengthes moving big pipe we used the same type knots a couple hitches and the tag taped to the pipe being pulled probebly bullet proof as well for this operation
