How tall does a pipe have to be to run across the floor?

The holes must follow a straight line across the floor and must ascend or descend so the pipe will be sloped 1/4 inch per foot. (If joists are 16 inches on center and pipes run across them at a right angle, holes should differ in height by about 3/8 inch.)

Can a drainpipe be run through a joist?

Metal plates protect pipes from nails. Running drainpipe through joists calls for meticulous work. The holes must follow a straight line across the floor and must ascend or descend so the pipe will be sloped 1/4 inch per foot.

How big of a hole do you cut for a drain pipe?

For a 3-inch pipe, use a drill and reciprocating saw to cut a hole about 4-1/4 inches by 10 inches through both the bottom plate of the room you are working in and the top plate of the room below. Cut away a 10-inch by 2-foot section of flooring. Assemble the approved fittings onto the top of the drainpipe.

How much pressure does a copper water pipe need?

For copper pipe, hot (~50 C) water should only flow at approx 5 ft/second. Flow of less than one or two ft/sec can also be a problem. Based on the diameter of the pipe (1/2 in type L), 0.72 gpm flows at 1.0 ft/second, so this would suggest a maximum of 3.6 gpm for the pipe (assuming 5 ft/second). Also, you must worry about the pressure drop.

How do you install a copper supply line?

Install a hammer arrester to each. Sweat all the parts. Anchor the pipes with at least one clamp―preferably two―at each stub out as shown. A copper supply strap attaches to the face of the studs. Pipes fit into notches or holes, sized and spaced for correct placement.
