I building an outdoor pavilion/kitchen and wanted to get some advice on the plumbing for hot/cold water lines. I am located in NJ so need to consider the freezing factor here. Need to run the lines from my basement into the pavilion
so here is what I came up with:

- Will dig a 36" deep trench outside my basement to go below the frost line.
- I purchased 1/2" type K soft copper so I can bend vs having to use fittings.
- I will surround the copper with armor flex insulation and put it into a 2" PVC pipe.
- There are going to me 3 ft deep concrete footings to support my pavilion walls, so will run the pipe under the footing
- I need to go about 2ft straight out of foundation, make a left curve to my pavilion area, and then go up so I am inside the pavilion wall (which is where the pipes will connect to sink). I will make sure all the lines pitch back to basement so I can drain/winterize
- When I connect the water lines in the basement, I will have some drain lines in the copper that I can remove the water from before winter sets in

Let me know what u all think.

It doesnt say how far from the house the pavilion is. I would consider running PEX for your water lines. You could run 3" PVC to the pavilion as a "conduit" and fish the PEX through it. That way, if anything happened to the PEX, you could always fish a new line through your "conduit". You could even fish electric or cable through it, too. I'm sure you'll have a TV out there.

Thanks.. The pavilion wall where the water lines come in will be about 6 ft from the foundation. I went bak n forth on copper vs pex, but decided to go with the thick copper. Thought about the TV thing as well, but I have that line included in my electric pipes.

PEX is much less likely to split from freezing. Just make sure you're plenty deep. With these weird winters, we could get some very cold weather.
