I'm moving the plumbing in a shower stall (no tub) and wanted to know if what I'm planning is OK to do. I'd like the shower valve to be on one wall and the outlet on the opposite wall, about 5.5 feet away. The hot and cold supply come from the crawlspace under the bathroom up the wall. Id like to take the outlet from the shower valve and route it back down the wall, into the crawl space, under the shower and back up the opposite wall. My concern is changing the direction of the water flow from the usual short path of directly upward from the valve to the longer distance it will be going. Too much pressure loss, air getting trapped, water hammer issues. Thanks again for your help. Jim

Your fears are groundless. No loss of pressure , no air being trapped although you have built a trap by running it under the crawl space. A better configuration would be to run it overhead in the attic and no water hammer will be involved. We offset shower heads all the time. Tun yours where you wish. Good luck, Tom

Thanks Tom! I was going to go the overhead route in the attic but I just had a heater/air conditioner installed up there and guess where they installed it... right where the water line would have to come up from the wall into the attic. Thanks again! Jim

Can you go through the walls?

The bathroom is down to the studs so I could go through the walls. Would this be better than going through the crawlspace?

Yes!

Tom told you exactly what I would have... Agree with Tom 100 %

Use soft copper pipe to get through the studs so you don't have to solder in short pieces of pipe.

Thanks for all the replies. Looks like I'm going through the wall studs with soft copper lines. Thanks again! Jim

Unroll the soft copper slowly as you feed it through the studs so that you don't harden it.
