Anyone know of a place within about an hour to 2 of George west where I can get 1600 feet of pvc in 3/4 inch that's not outrageously overpriced? Best quote I got so far is a company out of Georgia and with shipping to the loach toon I'm looking at $675. Anyone know someplace local cheaper?

There is a Ferguson Plumbing next to Tractor Supply in Beeville. You might look into PEX pipe also. I am running it instead of PVC for my water lines. I can buy 500 ft rolls of 3/4" on-line for $175 shipped to my house. Lot better than PVC and no glue joints.

Stx thanks for the heads up on that. I see tractor supply has 400 foot rolls of polyethylene flex coil pipe for 90 a roll. Is there a big difference between pex and poly? Where did you find rolls for that cheap?

The poly is okay but not as good as PEX to me. The splice joints on Poly are going to give your issues after a while when it gets really dry.

IIRC, PEX is made from polyethylene but the way it is formed handles freeze/stretching better...... That is a long run for 3/4", if it is a main house type supply.

Here is 500' of 3/4 potable PEX for $185 w/ free shipping.

PEX is crossed linked polyethylene. It is thicker walled, and as said before, will expand when frozen....not break. What are you supplying? If it is a home, I would look at 11/2" 200 class gasketed pvc. At that distance, 3/4" or even 1" will leave you under supplied. You will be spending more money of course.

What is the water line for? It is very important when running long lines to have the correct pipe to do the job. At 1,600 feet, you have an enormous amount of friction. Is the run flat? uphill or downhill? Gravity is a big issue when running water lines. You lose water pressure going uphill.

What type of soil do you have? Does it expand when frozen? does it contract when it dries out? Ground movement is what causes pipes to break. The ground moves a lot. More them most people realize.

PVC in 20 foot sticks with the attached bell is probably your best bet, but at 3/4 inch, you will have very little water pressure at the end of the run. If using PVC, it's very important to use purple primer and then clear, heavy duty glue. The primer softens the PVC and then the glue melts it together. It's not really a glue, it's more of a weld.

PEX is wonderful stuff. When used with quality metal fittings, it's the best way to plumb a house.
For long runs, it's weakness is in the joints. They fit inside the PEX and reduce the inside diameter of the tubing considerably. This will reduce volume even more over a long run when comparing the same sized pipe. And while the clamps are very good, odds are good that over a short amount of time, the movement of the ground will pull it apart.

Poly is cheap junk. Mostly it's found in mobile homes, but a lot of them dont even use it anymore. Home improvement DIY type people use it for running water from their well to their house in a continuous run because it's cheap and they get away with it because there are no joints in the run. Well to house, one solid length of tubing. It's brittle and over time, gets tore up by ground movement. In many places it's not allowed to be used because of how often it breaks.

The best pipe for long runs will be gasketed pipe. One end slides into the other end. No glue. There is a gasket inside the bell housing that seals the pipe and allows it to move in and out. For that length of a run, to have any sort of water pressure, you will need 2 inch pipe.

I am T'ing off of 1 water trough with a pump and running it majority flat and downhill with a very small section that will be the slightest of up hill to supply another 5 foot diameter round cement water trough by a protein feeder. I dont need alot of water pressure anyways even if it is just a trickle it doesnt really matter as the float system will be set high so it will not run very low in the trough anyways.

Since volume and pressure are not a big concern, I would price half inch schedule 40 in twenty foot joints at Lowes, then see if any feed stores or farm supply stores in the area can beat the price. My local farm supply store seems to decide what his price will be based on how long you visit with him and his mood at the time. I've bought stuff from him a lot cheaper then the box stores on a good day, and other days he wasn't even close.

If you look at a local store, go to the manager and tell them how much you're planning to buy and ask them if you can get a discount. They will sometimes make a deal. Can't hurt, and all they can say is no.

another thought ... it would be under $500 to buy 16x 100 foot cheap water hoses ...

If you are running 1600 feet and want more than a trickle you will need to expand the diameter. I thinking doubling diameter would be about right. Sometimes you just gotta bite the bullet.

agree, but if only filling and maintaining a water trough, doesn't seem like he would need much pressure at the end, even if merely a trickle.

It's a lot of money for a trickle.

it's a lot more money for more than a trickle

When I needed cheap, for a similar app, I used 3/4 pvc conduit - gray stuff in electrical dept - $2.05 a stick ($320 for ur app) - prolly get a discount buying 160 sticks, at Lowes - 70 miles away @Kingsville.
. Neat thing is don't have to buy couplings - don't need - has flare one end just slop some glue.
Stuff is tuff ( sch40 && is sunlight resistant) - way tougher than polyelethene & hoses - fairly crush proof.

Is that for ten foot lengths or 20 foot lengths? Lowes.com has 20 foot lengths of 3/4 Schedule 40 for $5.20 on their website. The bell that is part of the pipe at the end is easily twice as long as a coupling. If you use purple primer and heavy duty cement, the pipe will melt together and form a solid weld. When it breaks, it's the pipe itself that breaks, never the joint.

Does grey plastic conduit weld together the same way? My understanding is that the conduit glue is just a glue and it's not rated for any sort of water pressure.

We just bought a little over 7200' of 1/2", 340' of 2" and 220' of 1" for our tree farm and I think it was around $800 or so.

Make sure when you get the quote that its bell end. Thats not always the case. Ours was bell end.
