What size of pipe for a water line from well to house?

Interesting. While black plastic will be cheaper white schedule 40. But the white pipe in sections is more particle when it comes to repair and logistics. I have never had a freeze bust a white pipe. Crosses fingers.

..............You need to calculate Total head pressure , from the well motor to the end of the pipe ! This , in turn , determines the Hp of the well motor and diameter of the surface pipe to the final point of discharge . , fordy

Pressure drop is independent of head pressure, pump HP, or well motor discharge pipe size. If you run 1" PVC for 900' and flow 10 GPM, the pressure drop will be 23 psi regardless of whether the head pressure is 50 or 100 psig.

Pex is the new wonder pipe and can be installed without digging with a line boring machine across your lawn. Tools to work it are a little expensive but can be rented....James

I don't think you can direct bury PEX, but correct me if I'm mistaken. I'm confident that PEX is photo-sensitive, and needs to be protected from daylight.

Sun light yes, buried is protected from the sunlight....James

I love PEX. I've been using it since the 80s to replace all that black poly when it springs leaks. Quite expensive for the larger diameters though. I think 1.5" is around $3/foot.

They started using a blue, thicker walled pipe around here now, like black poly, but some tuff stuff. Don't know what it is called.

I have about 400 feet of it now, with the new well a year ago and new water line this fall to the barn.

Boring it in sure went nice, in a way more expensive, but they go under out buildings, trees, etc and so use less pipe as they can go in straight line, so not always real expensive to bore it in.

As others said, at that distance, 1.5 inch, more if you have money.

I think the blue stuff is what Darren was talking about...CTS poly or something...not sure if the CTS refers to "copper tubing size" as it sometimes does in plumbing or if it's the type of poly. I've noticed they use something that looks like that a lot in the Caribbean islands I've been to. No burial, just laid alongside the road.

My new well was connected to the water lines for my house and the outside pens, and they used blue plastic line - not black. I know we've got a couple of outside waterer's that use the black plastic line, and we have to be very careful when doing repairs with them so as not to break the water line below ground. We've also had problems with water lines developing holes due to thin walled PVC pipe and the glue eating through them. Just a little something to think about. If I had to guess on the size of the blue line, I would say it was 1 1/2".

It's black and NSF stamped. I had 200' pulled in under the creek with a directional drill and never had a problem. That was not embedded in sand. I'm not sure Lowes/Home Depot is selling the same stuff. I'd check a plumbing supply house. The stuff I used was CTS but the wall thickness was heavier than what I saw at Lowes. The bottom next to the creek was silt so the trencher went through it fast. The hill was rock and the trench for the pipe had to opened with a jack hammer. I ran 2" due to the uphill run and the distance, something over 1,000'.

No problems in over ten years.

I have used guard pipe in places where erosion or water flow might expose the pipe at other places.
