How to Install a Utility Sink Next to Washer

Having the best laundry room sink installed can make your tasks easier if you know the procedure of how to install a utility sink next to washer.

Laundry room utility sinks come in handy when washing or scrubbing large objects or many clothes. It is an ideal fixture to install in your garage, basement, or laundry room.

When placed next to each other, you can use the plumbing system your washing machine uses with your utility sink. It means that you will be saving money, time, and energy. You will also be saving space because you need not introduce another plumbing system.

Also, when you install a laundry room sink next to a washing machine, you reduce a lot of mess. Excellent examples are like soiling the room or dripping water all over the place when moving dirty or wet clothes or stuff between the two fixtures.

Fortunately, installing the two fixtures next to each other is fairly simple. You need to be patient and use the right tools and procedures.

8 Steps to Install a Utility Sink Next to Washer:

Step1: Collect the Tools Needed

Here is what you require;

  • PVC hand saw
  • Pipe splitters
  • Pliers
  • Plumber’s glue
  • Measuring stick
  • PVC Y-fitting
  • Sand paper or de-burrer
  • Wrench
  • Measuring stick
  • A cold and hot flexible tubing

Step 2: Take the Measurement for Drain

After collecting all the required working tools, you need to take measurements from the drains of both fixtures. The size gotten will help in connecting the two drains.

Start by disconnecting or closing the water supply. Otherwise, you will have some extra work of drying off the flooding water.

Next, measure the sink’s drain pipe from its connection to the wall or ground. Then measure the washer’s drain line from the bottom to the exact measurements you got after measuring the utility sink drain pipe.

After measuring the washer drain pipe up to the exact measurements of the sink drain, put a mark. The marked place is where you shall fix the Y-fitting that separates the two drains.

Step 3: Cut the Washer’s Drain Pipe

Once you mark the washer’s drain, cut it from that point to any place on the above venting pipe.

The washer consists of a T-fitting where water coming from the drain turns downwards and goes towards the exit. You will also need to cut that horizontal T-fitting.

After cutting the pipe, smoothen the edges with a de-burrer or sandpaper to eliminate uneven edges that may deter the proper connection of the lines.

Step 4: Fix the Y-Fitting and Connect the Utility Sink to the Washer Drain

When you finish with the pipe cutting, it’s time to connect the utility sink and washing machine to the same drain.

You need to pay attention when connecting the utility sink to the washer drain because it entails a lot.

If you skip anything or do it incorrectly, the entire process will flop.

First, connect your washer’s drain pipe with a PVC Y-fitting. The top arm of the fitting will connect to the above venting pipe.

As for the side arms, one will connect to the tube with water flowing horizontally. The other arm will attach to the line connecting the laundry room sink with its drain.

Secure the connections using the plumber’s glue or putty to avoid leakages. These plumber’s sealants are affordable and easily accessible in the hardware next door. They also connect the joints tightly and are waterproof.

Step 5: Search for the Water Sources

You cannot hook up the washer to sink without adjusting your water source. After finishing with the drains connection, you need to connect the water lines.

Start by investigating the location of the hot and cold water pipes serving your washer.

Mostly, you will find the two pipes running into a fitting located on the water pipe. At this hot and cold hookup point, disconnect the waterline.

Sometimes the water pipe may not contain the fitting. In such a case, find a bucket and place it under the water pipe where you will cut.

Then cut the water line at a place that is midway between the laundry room sink and the washer.

Remember to smoothen the cut edges of the pipe for easier connection. Threading the cut area with an appropriate tool will work out fine.

Step 6: Install a Pipe Splitter to the Cold and Hot Water Pipes

When you finish cutting and threading the water pipe, use a two-headed pipe splitter to fix a splitter on both the cold and hotlines. Ensure the splitter gets tightly secured by reinforcing it with a wrench.

The fixed splitter will help separate the cold and hot pipes from the water supply. One line heads to your utility sink while the other goes to the washer.

After connecting and securing a splitter to the cold and hot water lines, reattach the washer with the pipes. You can buy and install other pipes if you wish, or the existing ones are not in good condition. Whichever the case, use pliers or a wrench to reconnect the tubes.

Step 7: Attach Hoses to the Utility Sink

With the splitters in place, you need to connect them to the flexible cold and warm tubing. First, ensure that the tubing reaches the utility sink.

Use a red flexible tubing to connect to the hot water line and a blue one for the cold water. That way, differentiating them becomes easy.

Insert a nut to tighten these connections appropriately. A wrench will help you out.

Last Step: Connect the Flexible Water Tubes to the Sink’s Faucet Hookups

After fixing the splitters to the flexible hot and cold pipes, you should connect the tubes to the sink’s faucet hookups. Ensure that you seal and tighten all the connections.

When finished, open the main water supply to test if the connection works out perfectly. Look out for any leakages and seal them. Remember to switch off your water’s main supply when redoing a step or sealing a leaking drain.

If the water runs quickly and smoothly after the connection, you will have successfully installed your utility sink close to your washer.

You are now aware that utility sink installation is not complicated but requires much of your time and attention with the above information.

You also need your laundry room sink faucet to attach your washer to the laundry sink. The process is also straightforward and entails the following;

Assembling the Laundry Room Or Garage Room Sink Faucet

  • The first thing to do is to collect every item required in the process. You will need a plumbers putty, PVC pipe cutter, two copper pipes, propane torch, non-leaded solder, center screw, and fiber washers.
  • When you finish assembling the materials, you will have to look for the best location to install your garage or laundry sink and its faucet. Fix the laundry sink under a window in your basement. It should also be next to the floor drain.

In return, the sink will access natural light for better visibility and will drain off the water safely and effortlessly. Also, ensure you reinforce the sink by building a support frame.

  • Next, turn off your water supply to the sink area. If there’s no shutoff valve near the washer, close the main water supply to your house.
  • Then cut the main pipe supplying water in your laundry room and insert a Y-fitting. The cut should be 3 โ€“ inch wide. On each arm of the Y-fitting, apply glue and pipe primer.
  • Once you are through, connect the arms to the right and left cut-out pipe sections to enable wastewater to pass out of the laundry room sink.
  • After the connections, seal the joints firmly with plumbers to avoid any leakages.
  • Then connect two copper pipes to the cold and hot piping system from your kitchen to the basement. Afterward, cut the pipes and insert T โ€“ valves in the area close to the faucet attachment.

The valves will serve as air chambers responsible for preventing vibration and water hammer noise. Ensure the two copper pipes run parallel and that there’s enough room for the laundry room or garage sink faucet.

  • When all is in order, it’s time to fix the garage or laundry room faucet. Start by attaching the water supply’s bypass valves to your washing machine. Then connect the flexible tubes for the cold and hot water to the tap and the washer’s back.

Ensure you secure the flexible tubes snugly tight to avoid crimping them. Then insert the laundry room or garage faucet.

While connecting, ensure the cold and hot tap valves are attached to the right pipes. Use non-leaded solder and a propane torch to seal the pipes correctly and securely.

  • Once done, connect the tap handles for your laundry room or garage sink faucet. Fix them in the faucet’s union connections and screw them using a center screw. If necessary, insert fiber washers to boost the tightness.
  • After connecting the tap holders, put on the water supply to your washing machine and test if everything is working well. Check whether the water supplied from the cold and hot valves and taps are correct.

Always leave the bypass valves open as the washer will draw water only when turned on, washing or rinsing.

With the above information, assembling a laundry room or garage room sink faucet is not daunting. But the process requires substantial time.

Connecting a Laundry Room Sink and Washing Machine to the Same Drain

Most laundry rooms contain a laundry sink that acts as a drain for the area’s washing machine. One way this happens is by placing the washing machine’s drain hose on the sink’s edge.

With this in place, the water from the washing machine will go directly into the sink. It will then exit through the sink’s drainage.

But if your laundry sink has a drain pipe of 2 โ€“ inches, you can connect the washer drain hose to the sink. Smaller drains cannot accommodate the washer’s water volume discharged.

You will need to install a separate P-trap and standpipe to prevent water from backing up.

If you want your garage or laundry sink and washing machine to use the same drain, use the following step-by-step guide to connect them.

Step 1: Assemble the Required Items

Without all the proper materials needed, the connection process will fail. That’s why you need to collect all items required first. Ensure you have;

  • T-fitting
  • Rotary cutting tool
  • PVC glue or primer
  • Hack saw
  • Sandpaper
  • Rubber coupling
  • Hose clamps
  • Screwdriver

Step 2: Examine the Sewer Tube Near Your Washing Machine and Sink

The sewer pipe is usually a tube standing freely and with an open end. Check whether it has a tee connection. If not, you will have to install one.

Step 3: Close the Water Supply to Your Laundry Sink and Washer

The fixtures that supply water to your washing machine and laundry sink come with two supply valves each. One valve is for the hot water while the other supplies cold water. Turn them off.

Step 4: Unplug your Washing Machine

After disconnecting all the water supplies, unplug your washing machine’s power cable from the power source for safety.

Step 5: Cut the Sewer Tube

Cut the sewer tube in half, approximately halfway down when the washer gets safely unplugged from the energy source.

You will need to cut the metal pipe using a rotary cutting tool that has a metal blade. But use an ideal saw such as a hack saw to cut the PVC pipe.

Don’t forget to smoothen the cut edges with sandpaper.

Step 6: Fix the T-Fitting to the Sewer Line

After cutting the sewer inlet tube:

  • Connect a T-fitting to it.
  • Secure the T-fitting using hose clamps and a rubber coupling.
  • Use a screwdriver to tighten the clamps.
  • Ensure the Tee points towards the sink drain pipe direction.

Step 7: Attach a Straight Drain Tube to the T-Fitting’s Top

When through with fixing the T-fitting, connect its top with a straight drain pipe.

If the T-fitting gets made of metal, secure the connection with the drain tube using a rubber coupling. But if using a PVC Tee, attach it with the drain tube using PVC glue or primer.

Then keep the pipe steady by clamping it to the nearest wall or stud.

Step 8: Test the Connection

After securing the drainpipe:

  • Turn on the water supply and test if the water flows and drains as expected.
  • Don’t forget to plug in your washing machine and put it on.
  • Seal any leaking areas using a water-resistant sealant. If you don’t find any dripping or leakages, you will have completed the connection of your laundry sink and washing machine to the same drain.

Closing Thoughts

Installing a utility sink next to washing machine is easy to handle task and it has many benefits. You will evade certain inconveniences like dirtying your laundry room and spilling water all over.

What’s impressive is that you don’t need a professional to connect with you because the process is straightforward.

After installing the two fixtures, connecting them to the laundry room sink faucet is crucial. This process also helps you save energy and water. You will also save more space when your washing machine and laundry sink use the same drain.
