Does it make sense?
Preparing the Space
First thing first, has a small & compact bucket handy that can be placed under the curved portion of the P-traps. (the curved laundry sink pipe)
By doing so, you would be able to catch the water that would be coming out when you’re in the process of disassembling the pipes.
At the same time, you need to ensure that the water valves are turned off in order to prevent someone from accidentally turning on the water while the drain is disassembled.
Once the aforementioned steps are expedited successfully, the next thing that needs to be done on your end is to jot down the dimensions of your laundry sink pipe with the help of tape.
By doing so, you would be able to buy the correct size parts for your laundry sink.
Also, it will help you to get the new laundry sink pipe to the right size.
The best part is that you can easily buy these new materials from any hardware store.
Dismantling the Laundry Sink Pipes
This is one of the important steps and so you need to pay special attention to it.
To begin with, unscrew the P-trap connection from the sink’s tailpieces.
Well, if you don’t know what actually the tailpieces are then please allow me to explain them to you.
In fact, tailpieces are nothing but pipes that extend down from the sink and the drain.
In order to loosen them, you need to start with grabbing one nut at a time by your hand and then turn it counterclockwise.
You might be wondering what if nuts are too tight.
Well, in that case, you need to use adjustable pliers to loosen them.
If still, you’re NOT able to get any success then you must spray lubricate on the metal traps to loosen the threads.
The next thing that needs to be done is to turn the disconnected connections upside down to drain the water into the bucket and then set these pieces aside.
Well, in case the traps are connected to a common tee then you need to unscrew the connections to the tee and remove this part as well.
Furthermore, all the pipes that are present in the way need to be disassembled.
The Drain Tailpieces
Examine the drain tailpieces thoroughly, and in case, you notice them be too short or corroded then you don’t have an option but to remove them.
It is quite possible that damaged drain tailpieces are the reasons behind the leakage.
Removing them is easy and will not consume much of your time for sure.
All you need to do is to unscrew them from the drain by turning them counterclockwise with adjustable pliers.
Install the New Pieces
Once you’re done with the aforementioned steps, the next thing that needs to be done is to install the new pieces.
Now, it’s time to screw in the new tailpieces.
Measure their length and make sure they are long enough to extend to the top of the drainpipe in the wall.
Furthermore, if your drainpipe is under the floor then you need to make sure to extend the new tailpieces 2 feet above the bottom of the cabinet.
Well, if necessary you need to adjust the size of your new tailpipes simply by cutting them with a hacksaw.
In case, you’ve to cut the pieces then the best thing that you can do is to compare or match the new pipe with the one that you’ve removed previously in order to prevent any last-minute misadventure.
It is always advisable to use a pipe that is almost similar in dimension, that is, typically 1 ¼ – 1 ½ inches.
Furthermore, in case, you’re working on a kitchen sink, then you can consider using a PVC pipe since it doesn’t come with a risk of corrosion as a metal pipe does.
Put Your Sink Back Together
Once all the aforementioned steps have been taken care of, the next thing that needs to be done is to reassemble your sink by connecting the compression fittings with the pipes and tightening the nuts by hand.
Afterward, you need to install the P-traps.
Slide each trap up onto its perspective tailpieces.
Then, tighten the nuts.
Afterward, swivel them to meet the pipe going to the drain.
Finally, reattach the end of the trap and tighten the nut.
Finally, Test Your Laundry Sink
It goes without saying that once you’re done with finishing assembling your pipes, the next thing that needs to be done is to test the sink pipes and drains.
This can be easily done by filling your sink with water.
Afterward, you need to open the drain in order to let the water filter out.
It will ensure that the connection is tight and there are no further leaks.
Well, if a leak is occurring just because the connection is too loose then all you need to do is to tighten it by using adjustable pliers.
How to Install a Laundry Sink Next to Washer?
Before we dive deep into the discussion, you must be handy with the below list of tools in order to prevent any last-minute misadventure.
- PVC Y-fitting
- PVC hand saw
- De-burrer or small piece of sandpaper
- Two brass pipe splitters
- Threading tool (optional)
- Plumber’s glue
- Hot and cold flexible tubing
- Measuring stick
Measure for Drain
It goes without saying that before doing anything else you need to ensure that the main water supply is turned off in order to prevent any unprecedented event.
The next thing that needs to be done on your laundry sink is to measure how far the drain pipe connection is from the ground.
You need to be very specific in locating your existing washer’s drain line and be well-versed with its position, that is, whether it goes down into the wall or the floor.
Now, using your laundry sink’s drain line measurement, all you need to do is to measure up from the ground and make a mark on your washer’s drain line.
Yes, you guessed it, right.
This is where you would be placing the new Y-fitting that will separate the washer’s drain from the laundry sink’s drain in the next step.
Cut Existing Laundry Drain Pipe
This is a crucial step and needs to be given utter importance.
Failing to do so can do more bad than good.
So, cut the existing laundry drain pipe from the mark that you made to anywhere on the venting pipe that connects above it.
Just for your information, while you’re expediting the process, you must understand that you need to cut the horizontal T-fitting where the water from the washer turns downward towards the exit drain pipe.
Once you’re done with the cutting, the next thing that you need to do is to de-burr or smoothen the inside of the pipe where the cutting has taken place.
You can use a smoothening tool or even sandpaper for this purpose.
By doing so, you would be able to make sure that there are no rough or uneven edges when you’ll attach pipes in the next step.
Attach Y-Fitting and Add Laundry Sink to Washer Drain
In this step, you need to attach the PVC Y-fitting to the existing drain pipe.
You need to attach one arm of Y to the horizontal flow of where your washer drain exists.
Well, the top of the Y-fitting will attach to the venting pipe above.
The pipe that runs from your laundry sink needs to be attached to the other arm of Y-fitting.
Make sure all the connections are tight, waterproof, and most importantly, secured.
If needed, don’t hesitate in taking the help of a plumber as well as a plumber’s putty or glue.
Locate Water Sources
I’m assuming that you’ve expedited the aforementioned steps carefully and successfully.
And, if that is the case, then definitely, the drain would be in place.
Now, it’s high time to do something similar with the water lines.
First and foremost, you need to locate hot and cold water pipe connections near your washer.
Also, make sure that these run to a single fitting on the water pipe.
You need to disconnect the water pipe at this point on each of them, that is, hot & cold hookups.
Well, you might be wondering what if I can’t find this fitting?
In such a scenario, you need to cut the pipe especially if it’s a long one.
Make sure to place a bucket in place to catch the water present inside the pipe.
It’s always advisable to cut the pipe the midway between your washer and the laundry sink.
Well, if you need to thread the pipe at this point, go ahead and do so using a threading tool.
Add Pipe Splitter to Hot and Cold Water Lines
This step needs special attention and some basic skills as well.
You would be needing a two-headed brass pipe splitter for screwing the splitter onto the main water pipe for both hot and cold lines.
At the same time, you must ensure that the seal is complete and that you screw this one tightly.
For checking whether the connection is secured or not, you can take the help of a wrench.
This splitter will not separate the water supply from both the hot and cold pipes.
One line will go to the washer and the other one to your laundry sink.
In the next step, a splitter needs to be attached to the hot and cold water pipes.
Make sure to secure the splitter to these pipes.
Afterward, the washer needs to be reconnected to the existing pipes.
If you don’t have a budget constraint then you can also opt for new lines, again it totally depends upon your wish, and we at izzysmarthomeguide.com don’t recommend any such thing.
Using a wrench or a plier, you need to reconnect the lines securely.
Connect Hoses to Sink
Connect the flexible tubing from the pipe splitter to the sink’s hot and cold lines.
Make sure to have a red tube for hot water & a cold tube for cold water.
Be sure to hook these up to the appropriate pipe.
With the help of your wrench, you need to tighten these connections using a nut.
Connecting your new flexible hot and cold water tubes to your utility sink faucet hookups is definitely the last step.
Once you’re done with this step, make sure all the connections are tight and sealed.
Afterward, you may turn on the main water supply.
The next thing that needs to be done is to check for leaks and make sure water runs smoothly and quickly.
In case, you want to make some changes then you must do it only after ensuring that the water supply is turned off.
Assembling a Laundry or Garage Room Sink Faucet
- Plumber’s putty and knife
- Foam or rubber gaskets
- Nuts and washers
- Flashlight (optional)
Turn Off Water
As said earlier also, the first thing that you need to do is to turn off the water supply.
By doing so, you would be able to avoid flooding.
Mount Faucet with Gaskets or Putty
I’m assuming your laundry sink is having a pre-drilled hole.
If that is not the case, then you need to drill a hole in your sink.
Then, the next thing that needs to be done is to slide your faucet into the hole from above.
The new faucet comes with rubber gaskets and nuts in order to secure the faucet head onto the sink itself.
If needed, you may use a plumber’s putty to be sure that you get a tight seal.
Tighten Mounting Nuts
These little nuts are really important as they will tighten the faucet to your laundry sink.
In order to secure these nuts, you can use a wrench for tightening them from under the sink.
At times, it has been found that while tightening the faucet to your laundry sink excessive sealant or putty whatever you call it, emerges at the sides.
All you need to do is to clean them off using a soft cloth or a towel.
Thread Hot and Cold Water Lines
You need to take the ends of both the hot & cold water lines and attach them to the matching underside of the faucet handles.
By using your hand, you can tighten these connections.
If you’re NOT comfortable using your hand, then you can bet on a wrench or a pair of pliers whichever suits you.
Your mission is to ensure the seal is complete and secure.
Last but not least, you need to turn on the water and check for leaks.
If you find any leakage, then start looking for the loose connections.
The area under the faucet needs to be completely secured and sealed.
Also, you need to ensure that everything fits tight.
With the help of a flashlight, you can cross-check whether any gap or lose area is present or NOT.
Always turn off the water before making adjustments.
