water supply for washer/dryer

drjay9051

I am relocating my washer /dryer and dont know best way to run the plumbing. I have two choices. I can run the pipes into the attic and come down into new location or I can run the supply lines from the current location through a cinder block wall, 15 foot run and back in to the new location. I am not too keen on waterpipes overhead. I really prefer the outside run but here is my question? How to avoid a frozen burst pipe in winter. I suppose if the lines are deep enough no problem. What about where they come out and back in?? Just foam wrap? I thought I would run both lines inside a larger conduit and fill with expanding foam (Great Stuff). Is this overkill? How do I run through the block and give it a neat and secure look?

Thanks for the help

Assuming the washer/dryer are in a laundry / utility room, why not run the plumbing along the inside wall from the old to the new location?

That would run the pipes through my bedroom. I am relocating from bathroom (its a stackable unit) into my master closet (10x10). Bedrom between the two. Thought about building some sort of chase to run the pipes but would not look right.
