How Do You Install Kitchen Sink Drains?
You can improve drainage, prevent leaks and reduce clogging in your sink drain by rethinking the way you construct it. Instead of using one inch thin walled pipe and leak-prone compression fittings, use Schedule 40 1½ inch inside diameter pipe and some of the new flexible couplings that allow you to remove sections to retrieve valuables. Thicker pipe will withstand bumps without leaking, it drains better because of the larger inside diameter and is less likely to leak because the compression unions are replaced with glued-in. Here’s how to construct an improved sink drain: From the house drain, bring up a 2 inch floor drain as close as possible to the back of the cabinet by Tee-ing in, leaving at least two inches of pipe above the floor of the cabinet. Install a flexible reducing T on this pipe, leaving the clamp loose. On the straight section of the reducing T, install a 1½ PVC cleanout fitting. On the curved section, install the schedule 40 1½ trap, leaving that clamp loose as well s
