I recently found out I have a leak between the Water Meter and my house. Local utilty company fixed wather pipes in street and moved all meters from yards to sidewalks. Basiclaly updated there stuff. Question is.. Is there any preference on type of pipe to use to replace old. I was thinking of PEX as I have some left from a redo of a plumbing job for my cabin however not sure about under ground use of Pex... House was built in 1908 have lots of old roots. Main line goes under concrete porch through foundation into basement and house shut off valve has no knob and is stripped. Inside is a mix of galvanized, copper and some pex going to new water heater. I have trench dug from meter to house and line is exposed through foundation.

I would use PEX and put in the factory protective sleve wrap which comes in a roll. Great product.

most people around here use Poly pipe....i believe its rated for 100 years and is much stiffer than Pex

This is probably not why the code...but in a common sense analysis: If you were able to fill a tub somehwhat above the overflow line, then sit down...you could send a tidal wave over the rim!!!!!

I have 3/4 and 1/2 inch Pex. I need to find out my diameter of galvanized line looks to be 3/4 but need to measure for sure. I am having a hard time finding a female Pex connector 3/4 galv to 3/4 inch Pex. The websites I have searched are showing discontinuted. Also stumped about the PVC size I will need to protect pex going through foundation if I have/use 3/4 inch PEX then the PVC should be 1 1/2 inch correct? I will try to get a pic and post.

3/4" PEX is 7/8" o.d., so you can use 1" PVC or larger.

But, will ¾" pex be big enough or should he up it to 1"?

What does the local plumbing code or your water supplier require service pipe be made of???
Also what size do they require???

HE can do anything he wants, but I would oversize it if I used PEX, which I probably would not, especially for such a short run as this one. I might also be concerned with the roots growing around a plastic pipe and collapsing it.

Why should the trees care what size he uses?

Thanks all for the input I went to the City and found out they will allow pex if it is rated underground. So i have decided I will do Poly from the meter to the house as I will keep a standard and eventually convert to the PEX inside. The City supply line is 3/4. And the trees were removed about 3 years ago so I am not to worried about the Poly line collapsing.

My experience with tree roots and sewers is that you cut the tree down and "fight" the roots for the next 30 years. Cutting down the tree does NOT kill the roots.

I once even had a 1" lead line which had a root growing next to it and the lead had a 3/4" deep impression of the root where it was squeezed by the roor.
