Bathrooms typically have a lot more than one plumbing fixture, and itâs inconvenient and costly to to perform personal drain lines from every fixture to the houseâs primary sewer line. Plumbers link install a standard vent that permits waste and water without forming an air-lock to drain and drain lines in the ground underneath the the bathroom. The bathroom has the drain pipe that is greatest, hence will empty to the bathroom drain line.
The Toilet Drain
Connect a 3 inch PVC closet bend to the base of the toilet flange positioned in the ground where the bathroom will sit. A closet bend is sweeping 90-degree elbow that connects the flange into a 3- . There isn’t any need to install a trap under the the bathroom because bathrooms have integral traps.
Attach the end of the closet bend into a horizontal 3 inch drain pipe. The drainpipe runs horizontally only till it may descend for connecting using the houseâs primary sewer line. The pipe isn’t completely horizontal; it should slope in the approximate price of 1/4 inch per lineal. Since fluid can out-run waste, leaving it trapped in the drain pipe slope isn’t always better.
Apply PVC prep fluid and PVC adhesive, as directed on each productâs label, when connecting PVC pipes and fittings which are not threaded.
The Sink Drain
Attach a 2 inch sink trap assembly to the base of the drain stub that extends from under the the sink. The trap should come with two washers, one on each conclusion that slip within the pipes, as well as it is a connection and tighten. Don’t glue these connections.
Connect a PVC pipe that is horizontal . This pipe needs to be extended enough to achieve the area that is stud in the wall supporting the sink where it is going to attach to another 2inch pipe that is vertical.
A 2 inch sanitary-T fitting in the area to connect the sink drain pipe that is horizontal to some drainpipe that is vertical. The vertical drainpipe serves two functions; water drains downward, as well as the upper portion of the pipe ties to the houseâs principal vent stack. In the drain method, water locks could form with no upper vent part of the pipe. The sink vent serves both the toilet and also the sink.
Run the sink drainpipe that is lower, including collar connections or elbows asneeded to attain the 3inch drain pipe that runs from your toilet. Your bath-room lay out is depended up on by the configuration along with the path of the ground joists, but link the sink drain to the toilet drain within 6 toes of the toilet, if feasible.
The The Bond
Connect the sink drain pipe to the toilet drain pipe using a 2inch-to-3 inch sweeping-y-connector. The bathroom drain should be entered by the sink drain from over, as well as the 2 inch opening for the sink drain should prolong from the 3inch drain pipe that is horizontal to stop back-flow problems.
Cut a part from the 3 inch drain pipe when tying in the 2inch sink drain and use the PVC prep fluid and glue to support the the connections.
Cap the end of the 3-inch drain pipe before attaching it flush the toilet and fill the lines to check the pipe connections. That is the time to to find out whether a connection leaks.
