Lots Of Pipes Hang Down Under Floor Joists Basement

Step 4 cut the holes.

Lots of pipes hang down under floor joists basement.

Problem is that the current pipe all has a slope to it. Running drainpipe through joists calls for meticulous work. I figured i can just use a hole saw and make a notch in the joist for the pipe to sit and cover it with metal plate to prevent puncture. This ensures a constant slope and it makes for a very rigid installation.

The slope should be about 1 4 for each foot of pipe. Problem is that all of the hot water heat pipes hang below the joist and perpendicular to the joists. I m tempted to use simple copper straps to affix the pipes to the joists themselves. 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.

Step 3 understand the joist slopes. Then he screws that to the joist and goes to the next piece. The way this works bruce takes his plumbers tape and attaches it to a joist runs the tape down through the piece of pipe standoff then around the drain line and back up through the standoff. I need to do this with both gas black iron and domestic water copper pipe.

I want to finish my basement with a drywall ceiling. When you run your pipes through a joist you will have to be careful with your work. But they were run under the joists instead of through them as would be required by code for electrical wires. 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.

The lower section is about 8 wide to accomodate the two pipes.
