It may seem hard and scary to replace your kitchen sink plumbing with a new one. If you have the right tools to do the job, the time to finish it, and the ability to look carefully into details, then you don’t have anything to be afraid of. The task takes one hour at most, and requires no special skills at all; and the tools needed are found in almost every home. The steps are easy and fun and when you do it for the first time it will be exciting to do every time there is something wrong with your plumbing system and you want to save money and time.
What you need for the replacement is two water lines, drain pipes with trap assembly, adjustable wrench, medium pipe wrench, bucket, plumber’s tape and a towel. The process takes place in two major steps, first you need to remove the old sink plumbing, and then you need to install the new one. Each tool will be used in its right time during the course of the job, so don’t get confused about anything.
First of all, you have to shut down the water supply that is feeding the sink, and the valve responsible is often located under the sink itself or sometimes beside it. Then you open the faucets of the sink so that water can get out of pipes and pressure is removed. Use the adjustable wrench to unscrew the cold and hot water line. Detach both of the hot and cold water lines at the point that they connect to the water shut-off valve by unscrewing the bolt.
The drains can be disconnected afterward by reaching the nut placed under the sink drain and turning it with a pipe wrench. Then unscrew the entire pipe line connected to the main drain, this is located right under the center back of the cabinet floor. Prepare the bucket as the S trap will be full of waste water you don’t need to spill on the floor. Now you are done removing the old components and now the replacement begins.
The installation begins by using plumbing tape to wrap the threaded end of the hot water faucet, do the same with the hot water shut-off valve, and then screw the pipe line onto the hot water valve. Repeat all the previous wrapping on the cold water line. The next step is to fit the bottom end of the drain assembly to the main drain located as you left it in the floor cabinet. Don’t tighten the ends onto each other as you need to adjust the height of the assembly so that each side fits its related hole on the bottom of the sink.
Screw each side of the drain with it correspondent drain pipe and tighten the screw firmly this time. Use the pipe wrench to connect the drain assembly to the drain hole on the cabinet floor. Then you are done, but you have to let the water into the system by turning on the water valve and check for leaks, and if they are found, tighten the nearest connection to the leak until it stops.
