Connecting a Washing Machine to a Kitchen Sink





Introduction: Connecting a Washing Machine to a Kitchen Sink

About: Building energy efficiency/construction industry consultant; woodworker; casual (not hard core) cyclist.

I'm an apartment-dweller, and I managed to inherit a washing machine and dryer (no more collecting quarters and trips to the laundromat--yay!). But there are no hookups in my apartment (boo!). This is my solution to this problem.

Note that I never signed anything in my lease forbidding me to have a washing machine--you might want to check your own lease for details. Also, my downstairs neighbors are cool with their dishes rattling when I do laundry.

Step 1: Extension Hoses

None of the hoses that came with the washer are long enough to reach the sink. The supply hose is female hose fitting (both ends)--I just cobbled one together out of plastic hose repair fittings and clear braided tubing (all available from Home Depot).

I extended the drain hose with 1-1/4" ID braided tubing--it is a friction fit around the outside of the drain hose (see the second photo). I secured it with a hose clamp. This works fine with a corrugated drain hose; I'm not sure how well it would work with a smooth surfaced hose.

Step 2: Sink Connection

Another piece you need from Home Depot: a sink aerator thread to hose connection adapter (piece at left on photo; aerator at right). It's sold in the rack of small plumbing fittings (along with washers, sink replacement parts, etc).

I've found that hand-tightening the adaptor is about right--overtightening with a set of ChannelLocks makes the rubber washer squeeze out of its correct shape, causing a leak.

Adaptor gets connected to the faucet. Hose gets connected to the adaptor. Knee bone connected to the shin bone.

Step 3: Connection to the Washing Machine

The supply hose needs to be connected to the cold hose connection. You are going to be controlling water temperature with the faucet controls (hot/cold/warm). Since the rinse cycle is usually cold, you need to hook up to this side to make it work.

Note the hose cap on the unused hot side. This is actually important. The solenoid valves have enough slop in them that there is some leakage out of this connection, even when you're just running the machine on cold. Yeah, I found this out the hard way.

Step 4: Finishing Setup

You might notice the velcro ties holding the hose together (like this). I considered it good insurance, to keep the drain hose from flopping out of the sink mid-cycle.

Make sure all the connections are tight; turn on the water to the temperature you want it. Fire it up, and do your laundry!

Note that if you wanted to do a cold rinse, you will have to change the faucet settings mid-cycle.

Step 5: Wrap-up

When you disassemble the hoses, be sure you have a bucket around to drain them out.

Step 6: Wrap-up, Part Ii

The second use for the velcro ties is to keep the hoses in place, when the machine is not in use.

Yay! Clean underwear!

    New to group.
    What size washers can be used in apt?
    What voltage needed?


    I live in an apartment and I inherited a pair of front load w/d for an early wedding gift. I am trying to set up the washer. I have a garden hose running from my shower head(only place i could get my adapter to screw onto) and that goes to my cold water inlet on the washer. I'm using corrugated pipe for my drain and going to my bath tub. Both hoses are 25 feet. Not sure if that matters?
    I can't get the washer to fill. I'm not sure what is up. Do I need a hose hooked up to my hot water inlet? The washer has an extension cord for power hooked up. where is doesn't have a plug in. No way around that. Please help me!! Thanks

    This is 5 years too late but I'd thought I'd share my experience anyways. I had the same problem getting water in & I just adjusting the water temp & I originally had it set to cold/cold but when I turned it too warm/cold or hot/cold it filled with my problem is it won't fill up for the rinse cycle any suggestions anyone plz!

    Some washers won't fill if the drain hose isn't higher than the washer (mine is one). I had to secure the drain hose about waist-high to get it to work.

    Have you had any drain backup issues? I am afraid to try this as this may cause my condo and the condo below to flood because in case doesn't drain fast enough. Any thoughts?

    Can i get an adaptor so i can use hot and cold water in my washer?

    What about a hose to faucet adaptor? I was using a quick-detach adaptor from Home Depot which was neither quick nor detach, it nearly broke my fingers every time I used it and once broke a dish I had in the sink from the force of the jerk and it pulled really hard on the faucet. But without it, how do you twist the hose into the aerator? Can you recommend one? My machine was idle for a while, but I'm moving and want to start using it again. I tested to make sure it survived the move, and the adaptor was the same torture as before . . .

    Thanks very much.

    how can i change washing machine's belt meself??


    Just found this great article. I have a question: I've lived in my
    apartment for over 10 years, where the faucet was original to the 1920s
    building, and it handled my portable machine just fine. Finally though,
    it did begin to leak. The replaced faucet began leaking within a day.
    Tightening some of it worked for about 2 months, until I walked in
    during a wash cycle and found water spraying straight up in 5-foot arcs
    in several directions. I would like to insist the landlord purchase a
    faucet that can handle the washing machine. What specs of faucets would I
    look for for that? For example, American Standard told me they never
    test for attachments like this and do not recommend allowing such usage.
    That was a surprise to hear. The faucet is a wall-type, 2 holes, eight
    inches across, and I know the cost needs to be reasonable. Thanks.


    what is important to remember is that IF you do not turn the faucets off after your cycle they cause mixing in the risers. This means that the apartments above and below that share your water can have scalding hot or really cold showers. This is most common in hi-rise construction and is a big tipoff that someone has an unacceptable hookup. To avoid this for everyones safety please install check valves on the hot and cold FEEDS to the faucet. These are also available in hose form at home depot. One on hot, one on cold.

    Thanks for the nice comment! I just bought the hoses from Home Depot, on the same trip for the rest of the fittings. You need to go over to the tubing stock area (plastic tubing on rolls), have them cut off the right length, and then get fittings as needed to connect them. Alternately, you could buy a regular washing machine hose, if it is long enough.

    If anyone knows how people in New York hook up a washing machine to their bathtub. Please leave the information here. Thank You.
    Be sure to use a snare catcher for the water going out or you will start clogging up your plumbing. An amazing amount of lint collects and that gets really expensive.
    They clamp on the water outlet hose with a hose clamp AND you should also use a hair snare for the sink as a back up. Hardware stores & home improvement stores have both. You can also buy a battery operated water alarm. Ones that just set off an audible alarm - and ones that dial a phone number in case of a leak.

    I hooked a Haier portable washing machine to my shower. I did not use braided tubing and clamps-- just bought an extra washing machine hose and a coupler to extend what the machine came with. You can also use garden hose, since it's the same size as washing machine hose.

    Basically, I attached a diverter (meant to add a handheld shower sprayer to a regular shower) to the shower nozzle. This way, I didn't have to remove & add the showerhead-- just turn a lever. Then I added an adapter from the diverter's 1/2 inch pipe thread to the washing machine hose's 3/4 inch thread. The washing machine fill hose attaches to the adapter-diverter combination.

    On my machine, the drain hose has to be in an upright position or the washing machine won't fill, so I attached it with a suction cup to the back of the shower. Definitely use a drain screen-- the lint builds up quicky.

    Have you had any issues with the washing machine draining too fast for the kitchen sink to keep up?

    The only problem I have had is when enough lint had come out of the machine that it blocked the drain. Overall, the sink seems to give you enough "buffer" capacity to keep up with a washing machine draining. Of course, that will depend on the size of your sink and capacity of your drain.

    I'd definitely recommend being nearby when you're running this setup--I usually wandered back into the room when it was draining to check on it, and I never left it to run a load unattended.

    You can find a "quick release" adapter too. It allows you to clip onto the kitchen sink faucet and unclip with a single motion. The one I have still has an aerator on it when I unclip, but I got it overseas. The ones I have seen here ( at ACE Hardware in the plumbing section ) don't have an aerator on the adapter parts, so if you want to have the aerator when you aren't using the washing machine, you'd have to unscrew the adapter and put the aerator back on. If you're not attached to your aerator, you can put the ACE adapter on and leave it. Then you simply clip the quick release on and off as you need to use the washing machine.

     do i hold button red button in while putting it faucet

    kinda like those quick release adapters you find On Portable Dishwashers

    attach one woman's pantyhose knee hi to the outlet to prevent junk from the drain water clogging the drain over time.  Anyone else have a big problem with sand accumulating in the screen of your washer;s water inlet?  It's often I had to clean that inlet in coastal FL.

    Me too!!  This is exciting.  I didn't want to sell my W/D as I downsized from a house with garage to a smaller dwelling without hookups.  My friend bought this and that to extend the hoses but I haven't used his 'system'.  I will implement your method and feel confident I can have clean clothes by tomorrow.    Just last night I saw 4 police cars at a laundramat.  I don't wanna go to a laundramat.  Thanks to you I don't have to!
