Hi Community,

This is my first post, so please excuse me if I break some etiquette :smile:.

I am replacing a water main to my house. I am using a 3/4" PEX-b hose for that, sleeved in 2" PVC. My problem is this: I have to get the new line into the house, and to do that I need to bring it up above ground, over the foundation, and into the house. Going under or through the foundation is not an option.

So ... what do I do with the line when it needs to come above ground and into the light? Should I transition to copper underground and then come up with copper? What do people normally do?

Thank you!

Alex

Welcome to the forums, Alex. Coming above grade is not an option. Where are you located? Your profile is not complete. Some areas like Arizona and more arid places, you may get away with it, but for the norm you will have to deal with freezing pipes. I know you have reasons not to perforate the foundation, so let us in on it, as it is done mostly all the time, and properly sealed afterwards.

I am located in the San Francisco Bay Area, so freezing isn't a problem. My existing mains come above ground. It's standard practice.

I can't perforate the foundation because:
1. It's old and likely to get damaged
2. In the "crawl space" I have only about a foot of clearance between dirt and wood. Even if I did perforate it, I wouldn't have access underground without pulling up the floors and excavating a lot.

You sort of answered my implicit question of "how is this usually done?" -- I guess the answer is "it's not done". (!)

But in my case, I have to. I was going to transition to copper inside the PVC sleeve and then come up with that.

Is that reasonable?

Have you considered continuing the sleeve into the house using 2 long radius 90° ells or 2 45° ells?
