Doing plumbing under the kitchen sink can be a difficult task. Not only are there many steps that must be taken, but they can also be messy and time-consuming. If you want to do your own plumbing work, the following 8 helpful steps on how to do plumbing under the kitchen sink will help make this job much easier for you!
How to do Plumbing Under Kitchen Sink In 8 Steps
Step 1: Turn Off the Water
People often forget to turn off the water before starting to work on this kind of project. If you are not sure if it is turned off, find an outside faucet and shut it all the way down.
Step 2: Prepare Your Work Area
Before you start nailing boards to your cabinets or unclogging a pipe, make sure that there is ample room for movement around your kitchen sink area because things will get messy!
Clear out any tools so they do not bump into anything under-sink-related when moving them in and out during your plumbing process. Ensure you have enough ventilation since fumes from whatever chemicals you choose to use can be dangerous. If desired, do not forget about safety glasses, latex gloves if desired), protective clothing, and a face mask.
Step 3: Remove the Old Drain Assembly
Remove the old drain assembly by disconnecting it from under your sink or just below where you find most of your pipes located in that area.
Pay attention to how everything goes together so that when you are finished, they can go back just as easily for future plumbing jobs around kitchen sinks if need be. Do not forget about putting some plumber’s putty on the bottom of each pipe before re-connecting them to make sure no leaks will occur!
Step 4: Clean up Under Sink Area
Before installing new parts, clean out all debris underneath your kitchen sink. A good way to do this is with an old rag taped at one end, which you can stick underneath your sink. Scrub out the entire area with a brush dedicated to cleaning up under kitchen sinks.
Step 5: Install New Drain Assembly
Once you have thoroughly cleaned up all debris, it is time to install new drain assembly parts that will replace old ones removed earlier on during this process.
Following set-up instructions included, make sure everything fits properly and connect pieces together tightly! Another tip is cutting off excess pipe length with wire cutters if needed so that they fit nicely around the area without having too much excess material hanging out from each side once reassembled.
Step 6: Test Plumbing Under Kitchen Sink
Test plumbing by turning the water back on at the outside faucet head or through one of the pipes located under the sink. Run water from both hot and cold taps for a minute or so to make sure everything is in working order before moving on to the next step!
Step 7: Seal Drain with Plumber’s Putty
Apply plumber’s putty around the top of each drain pipe before re-installing into drain assembly. Doing this will help prevent any leaks that could form down the road down the line, especially if your kitchen sink experiences a lot of use over time.
Step 8: Finishing Touches and You’re Done!
Once you have completed all previous steps, it is time to do some finishing touches, such as putting everything back in its rightful place, wiping up any messes made during the process, and congratulating yourself on a job well done!
How Does Under Sink Plumbing Work?
The plumbing under a kitchen sink is typically a one-way system. This means that the water flows from the hot water tank and supply lines, through the faucet and down the drain. It doesn’t flow in the other direction back up to the tank.
The traps on either side of the faucet keep sewer gas from coming up the drain. This is why you need to vent your kitchen sink plumbing and should not put garbage disposal under it.
What Pipes Are Under A Kitchen Sink?
Under the kitchen sink, you should have one supply line and a P-trap going to each faucet. This supplies hot water through one pipe and cold water through another.
When you turn on either of these valves under your sink, both lines are full of water at first but only the hot side heats up while the cold stays cool (assuming you have a hot water tank). There is usually also a drain line going from the sink to the trap and then down to the sewer. This line has a clean-out plug so you can clear out any clogs.
In conclusion, doing plumbing under the kitchen sink is not as daunting of a task as it may seem. Just remember to take your time, be organized, and use the proper safety gear, and you will be finished before you know it! Happy plumbing!
