HDPE vs PVC vs PEX

We are going to be replacing water lines in the near future. Our engineer has already contacted the city and told us 2” main line with 3/4” service lines would provide sufficient pressure for the number of homes we have on this particular street. We are struggling to identify what material we would like to use. Everybody has a difference in opinion.

  • I’ve heard pex will leak if buried and I don’t like the idea of the crimped connectors or shark bite fittings.
  • PVC is the easiest but this street is over a 1000 feet long so I am fearful of the bulk amount of glued connections
  • HDPE seams to be the best bet for the mains but I’m struggling identifying how to convert to 3/4 “ to run to the homes. Do we step down to 3/4 pvc or HDPE? I’ve worked with HDPE a life time ago and have witnessed the fusion / welding process for splicing smaller diameter pipe together so I am not scared of that part of it.

We will be handling installs our self. There’s no local building code we have to worry about. How would you go about doing this?

I would stick with PVC.

It’s tried and true, and 99% of maintenance staff can fix it.

2” PVC comes in up to a 20’ length. And you can easily install 2” x 2” x 3/4” T’s.

I get that you are not scared of the Welding part, but do you plan on being there to fix every leak/break? Probably not.

I don’t know all of the variables in this project, but 2” PVC actually has a slightly larger internal diameter than 2” HDPE, and headloss could be an issue over this length.
