How to install dishwasher in laundry

Hello @bobfossil

Welcome to the Bunnings Workshop community. It's a pleasure to have you join us, and thank you for sharing your question about your dishwasher.

In this particular scenario, I suggest moving the washing machine to the right and placing the dishwasher in the middle. The reason for this is that there is a greater chance of food particles getting stuck in an extended hose versus a washing machine that only deals with lint and water.

In order to split the mounting point on the washing machine tap, I suggest using Nylex Brass Two Way Manifold, this unit is sized at 20mm and will fit both the washing machine and dishwasher. To extend the inlet hose, I recommend using Boston 2m Double Ended Washing Machine And Dishwasher Inlet Hose in conjunction with Brasshards 20mm Brass Threaded Hexagon Nipple and Kinetic Heavy Duty Thread Seal Tape. You'll only need to extend the inlet hose of the washing machine. The dishwashing hose will be long enough to reach the washing machine tap.

To extend the outlet hose of the washing machine, I propose using Pope 25 x 19mm Barbed Reducing Joiner along with Kinetic 2m Grey PVC Washing Machine And Dishwasher Outlet Drain Hose. Carefully look at the ends of the outlet hose so that you will not accidentally install the barbed joiner in reverse. Use Kinetic 17-32mm 304 Stainless Steel Hose Clamp to clamp both ends of the barb. Failure to clamp the hoses will cause them to leak.

One last item to attach to the dishwasher outlet hose outlet is the Kinetic PVC Washing Machine Hose Outlet U Bracket. This will prevent the hose from slipping out of the laundry tub.

Please keep us updated with your progress, we look forward to seeing your washing machine and dishwasher installed perfectly.

If you have any other questions regarding the installation of the parts, please don't hesitate to let us know.

Thanks very much for your detailed response. In the end both could be installed side by side without extending the inlet or outlet hoses so that was convenient. The 2 way manifold is working well. The next step will be a bit more involved, it would be nice to place a bench over the units and install some cabinets above. We'd also want to replace the existing sink/cabinet and make sure the dishwasher + laundry inlet/outlets/electric cables are hidden away. Does that all sound reasonable? We'd have to get some help from a plumber/electrician, does Bunnings provide those kind of services?

It's great to hear that worked out for you @bobfossil.

What you mentioned sounds entirely possible. With professional assistance to move the plumbing and electrics, I can't see any issue installing a new sink, bench and cabinetry. We don't currently offer plumbing and electrical services, so you might like to use a site similar to hipages to search for qualified professionals.

Let us know if you would like to install the bench or cabinetry yourself, as I trust our helpful members will have plenty of advice. Whilst in the planning stage, I'm sure you'll find this guide useful: How to plan a laundry renovation. You'll also find some great inspiration with our Top 10 most popular laundry renovation projects.

Please let me know if you have any questions.

Thanks again. I do have a couple of questions if that's alright, here is the basic plan for the revamp:

- Remove existing sink + cabinet (tbh not sure where to even start here but I can investigate more)

- Get a plumber to add new tap(s) for the washing machine/dishwasher that will be hidden by the new cabinet + get things ready to replace the existing tap with a mixer (spoke to someone I found through hipages already, thanks for the suggestion)

- potentially replace flooring (any advice on some waterproof flooring here? To minimize hassle I was thinking I could lay some vinyl sheeting over the existing tiles but I think it might be a bit of work to make it even underfoot beforehand so perhaps I may just rip all the tiles out first. At the very least I would need to replace those tiles that get damaged getting the cabinet/sink out)

- install new cabinet

- install benchtop with sink (seeing as there's only room for the one cabinet underneath on the left hand side, I will need to add some kind of support on the other side for the benchtop to rest on, do you have any suggestions there?)

- install tiles for a splashback

No rush but any advice is welcome, I haven't done this before which would be pretty obvious 😉

Hello @bobfossil

I always suggest making a list and taping it to your laundry wall. This will remind you of the steps that you'll need to make. Disassembly is at the top of the list. Capping off the hot and cold taps will be a good starting point for you. Once the area is clear, you can now decide if you're putting new floor tiles in or just laying down vinyl flooring.

The final position of cabinets and machines is critical and must be marked off on the wall to give the plumber a reference on where to put the taps. The plumber will have to do a return visit to connect the laundry tub to the outlet pipe. Once the plumbing is done you can call on the electrician and have them move the powerpoint to its new location. Once the trades are done the rest is up to you. Fitting the base cabinet, putting the benchtop on which by the way is supported with slim angle brackets on the other end.

Next is the laundry tub, it usually comes with a template on where to cut. Just a friendly reminder to make sure that you are within the interior boundaries of the base cabinet to prevent any accidental cuts. It's then followed by the wall cabinets and then the splashback. I've placed a few images to give you an idea of what to look out for and how the benchtop is supported at the other end.

If you need further assistance, please let us know.

Hey EricL, how to deal with if the laundry tub had only one inlet to absorb water…. I.e. at present only the Washng machine drain outlet goes into this…. Can I combine/join both the drain outlets and make them them as one outlet into the laundry tub??

Thanks

Hello @Skyel2022

Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about installing two machine outlets into a single waste outlet.

It is possible to install two outlets into a single sink trap. I suggest using FIX-A-TAP 50mm S And P Trap, this would be the easiest way to connect two machines into a single outlet. Please keep in mind to make sure that the machine hoses are long enough to reach the inlets.

If you have any other questions we can help with, please let us know.

Thanks a lot EricL for your response and details. Can you please advise if Bunnings located near Ashfield, NSW 2131 or near by stores can arrange a service for the above??

I would be more than happy to get it done by Bunnings rather than doing it myself if possible.

Regards

Hi @Skyel2022

Technically the store offers a Dishwasher Installation Service and it is for a like-for-like straight swap. I'm not sure if this extends to washing machine installations. Please be aware that new installations will incur extra costs. If you can give me the name of the closest store to you, I can make some enquiries for you and see if they will be willing to extend the service to include an extra machine and the installation of a new sink trap.

If you need further assistance, please let us know.

Eric

Skyel2022

Yes the nearest store is Ashfield, NSW and the postcode is 2132…. Other nearostore would be Bunnings, Greenacre - 2190…

Appreciate your help with this…

Thanks

Hello @Skyel2022

Thank you very much for your patience, I'm so sorry but the dishwasher installation service at the store does not cover washing machine installation. My best suggestion is to post the job on either Airtasker or Freelancer, you can also search for registered plumbers in your area. Just make sure to post as much detail as possible when describing what you want to be installed, this will give you a good chance of getting an immediate response.

If you need further assistance, please let us know.

Hello Eric,

Thanks for the post! Solved a lot of issues for me. I have been successful at installing my dishwasher into the laundry.

Is there an alternative to the Nylex brass two way manifold? https://www.bunnings.com.au/nylex-brass-two-way-manifold_p0176445
If I were to install this, the height of the manifold + the height of the dishwasher fitting is too large for the space that I have.

I have 185mm to play with overall.

I am currently manually changing the cold water connection as and when needed. Not ideal!

Something like this would be ideal, but I am not sure if this product is appropriate given all have a hard thread (not plastic) https://www.bunnings.com.au/holman-2-way-y-tap-outlet_p3120268

Thanks in advance for any suggestions you can give.

🙂

Hello @JMK007

Welcome to the Bunnings Workshop community. It's fantastic to have you join us, and thank you for sharing your question about your dishwasher hose installation.

I suggest adding these two pieces to your laundry tap. First is the Brasshards 20mm Brass Female / Female Threaded Elbow. Please make sure to use a Kinetic 12mm x 10m White Standard Thread Seal on the tap before screwing in the elbow. Second is the Brasshards 25 x 100mm Galvanised Pipe. Again, please make sure to put thread seal on both ends to prevent leaks.

From this point, you can now install the Nylex Brass Two-Way Manifold without having to worry about space. Please note, I suggest putting at least four rounds of tape around the tap. The elbow does not need to be screwed all the way in, but it must be facing in the right direction when you install the two-way manifold. You'll see what I mean once you have the elbow and extension piece attached.

If the space is still inadequate, I suggest getting a Kinetic 1.2m Washing Machine/Dishwasher Double Ended Inlet Hose in combination with a Brasshards 20mm Brass Threaded Hexagon Nipple. Connect the hose to the tap and place the brass nipple at the other end which will allow you to connect the two-way manifold.

Please keep us updated with your progress, we look forward to seeing your washing machine hose connection sorted out.

If you need further assistance, please let us know.

Eric

THANK YOU!!! That is wonderful.

Hello again Eric,

Any suggestions for an alternative to the Nylex 2-way manifold? All the other parts you mentioned are available.
I can't get it at my local store and its 'out of stock' for delivery.

Thanks so much.
Justin

Hello @JMK007 (Justin)

You can also try the Pope 2-Way Brass Threaded Tap and the Holman 2-Way Metal Tap Outlet. There are other options in the garden hose and accessories department. But these two are the ones I would recommend next to the Nylex manifold. In regards to the Holman series, you'll need to unscrew the snap lock adapter at the end of the outlet, the thread size is standard and will fit 20mm BSP fittings.

In essence, you're looking for a garden tap splitter, but I suggest looking for the strongest one you can find and preferably made of brass.

If you need further assistance, please let us know.

Eric

Thanks Eric! I was able to purchase the Pope 2-way brass threaded tap this evening, and have successfully installed it.
This option also solved the issue of limited, vertical space.

Hello @JMK007

Thank you for posting that update on your split tap assembly. It's good to see that you got some extra space with the Pope 2-Way Brass Threaded Tap. I suggest just keeping an eye on it from time to time to make sure that it does not leak.

If you need further assistance, please let us know.

This is EXACTLY. What I needed. I spent the whole morning online trying to figure this out myself, a this even has the links to the exact parts. Thanks you Eric.👍🏼

It's great to hear that @EricL's advice helped you out too, @influenced. A big welcome to the Bunnings Workshop community and please let us know whenever you need a hand with a project around the home or garden; we're here to help.

Hi EricL

I have the same situation and I have attached the Nylex Two Way Manifold and it leaks ? Between the tap and the manifold no matter how tight I twist it. I also have plumbers tape around the tap. Why would it be leaking ?

many thanks

Kristie

Welcome to the Bunnings Workshop community @Kristie1984. It's wonderful to have you join us, and many thanks for your question about attaching an adaptor.

The connection between the adaptor and the tap does not require thread tape, though I understand why you've added it if it leaks. Was there a flat rubber washer inside, similar to the one I've pictured below? There should be, and that's what seals the connection.

If an adequate amount of thread tape was added, I'm unsure as to why the water would still be able to bypass it and escape in that area. Are you using a tool to tighten the adaptor or your hands? Hand tightening would likely not be sufficient to compress the tape and form a seal. Try using a set of multi-grip pliers to tighten the fitting.

Please let me know if you have any questions.

Hi Mitchell!

thanks for the quick reply!
yea it has the rubber washer inside, exactly like that.
I tried with no plumbers tape first and it sprayed out like a sprinkler, then I added the tape and it just drip leaks now, I tightened with my hand first then pliers, but when I try and turn it the whole thing moves….. maybe I’m just not strong enough 😀
