Connecting Old Garage Floor Drain To The Stack

A garage drain is also great for rinsing and cleaning the garage floor so all the dirty water doesn t end up on the driveway.

Connecting old garage floor drain to the stack.

I tried pouring a bunch of water down it to see if i could find the exit but could not. As water drains down the steep slope at the wye it can create a siphon effect such that water will be sucked out of the trap. Cut out a section of the stack or drain with a reciprocating saw and place the section in a heavy bag as it may have sludge on its interior. Temporarily run pipe longer than it needs to be so it comes near the old pipe.

It appears to be clogged with lots of dirt pebbles and leaves. If the owner wants to install a trough drain then it must be plumbed and be pre treated ran thru an oil interceptor. I ve never worried about it too much but with some heavy rains recently i discovered it doesn t work. Branch drain lines run horizontally though with a slight downward slope to connect each of the fixture drain traps to soil stacks which in turn will lead to main drain lines.

Installing a garage floor drain is a convenient way of controlling any water that drips off your car and onto the concrete floor. A drainpipe attached to the p trap goes into an opening in the wall. And the empty trap will allow sewer gas to flow into your home. The waste vent runs from your main drain line to prevent back pressure in the main sewer line.

Through the stack sewer gases are carried up to the roof through vent lines. Would this drain go to the sewer. Keep in mind that the floor will need to be sloped toward the drain to allow water to flow toward it. Branch drains are often completely hidden by the finished wall ceiling and floor surfaces.

Behind the wall where you can t see a vent line and drainpipe lead to a soil stack which is the control center of the wastewater system. I have a drain in my garage floor. Prime and glue two 5 inch pieces of pipe to a tee fitting. To join a new plastic drainpipe to an old steel pipe run new pipe into the room.

Drain pipes take the wastewater to the soil stack. Put on heavy rubber gloves. Connecting a trap to a vertical drain with a wye fitting and a 45 degree elbow seems like a good idea. Residential garage drains are prohibited from connecting to the sewer drainage system in our jurisdiction.

This pipe can be interrupted at any point up to 4 feet from the vent shaft that generally exits your home from the roof or the side of the home.
