How to Disconnect Plumbing Under Kitchen Sink
Before you start disconnecting the plumbing under your kitchen sink, make sure to turn off the water supply. This prevents any water from leaking and causing a mess. You can turn off the water supply by locating the shut-off valve under your sink or by turning off the main water supply in your house.
Steps for Disconnecting Plumbing Under Kitchen Sink
The first step is to remove any items stored under your sink to give you more room to work. Then, using an adjustable wrench, loosen the nuts that connect the P-trap to the drainpipe and the sink tailpiece. Once the nuts are loose, you can carefully remove the P-trap and set it aside.
Next, use pliers to loosen the slip nuts that connect the drainpipe to the sink strainer. Once the nuts are loose, you can remove the drainpipe and set it aside. Then, using a screwdriver, remove the mounting bolts that hold the sink in place. Once the bolts are removed, you can lift the sink out of the countertop.
To disconnect the hot and cold water supply lines, use an adjustable wrench to loosen the compression nuts that connect the supply lines to the shut-off valves. Once the nuts are loose, you can remove the supply lines and set them aside.
