House next door in process of a gut reno on and will eventually rent. As I travel a lot and just in general, wanted to reduce the potential problems so did manifolded PEX (pic below). Instructions to renter and wife (if I am out of town), if there is a water supply problem of any kind, in any bathroom, shut this bathroom off at the manifold, move on with life (3.5 bathroom house) and call me in the morning. Will label it clearer, house is in process and plumber wrote it on the lines. Valves at bottom go to washer and laundry sink.
