Dishwasher installation and plumbing

Our licensed plumbers connect, replace and plumb in dishwashers of all makes and models, in homes, rentals and small businesses. These are the dishwasher jobs we’re called for most.

New dishwasher connections

We connect the water supply and the drain hose, fit an isolation valve if there isn’t one, then run the dishwasher and check the connections for leaks.

Water supply · isolation valve · drain connection

Dishwasher replacements

We disconnect and remove the old dishwasher, check the isolation valve and flexi hose it was running on, and connect the new one in its place.

A dishwasher where there wasn’t one

No dishwasher point in your kitchen? We install the tap, waste and drain connections needed so the kitchen can take a dishwasher.

New water point · new drain · sink waste

Integrated and built-in dishwashers

Integrated and under-bench dishwashers fitted into the cabinetry, including cut-outs in the cabinet sides for the water and drain hoses when the recess doesn’t have them.

Kitchen renovations

Building or renovating? We work with your builder or cabinet maker so the dishwasher plumbing is in the right place before the cabinets go in.

New kitchens · renovations · cabinet makers

Leaking dishwasher connections

Water under the dishwasher or in the sink cabinet often comes from a worn isolation valve, a loose fitting or a burst or split flexi hose. We find the leak and fix the plumbing.

Getting ready for your dishwasher install

A few checks before we arrive make the job quicker. If your old dishwasher is leaking now, turn off its isolation valve under the sink and call us. Our phones are answered 24 hours a day, 7 days a week.

Before we arrive

  1. Measure the space against the height, width and depth in the dishwasher’s installation guide.
  2. Keep the box contents: the installation guide, hoses and brackets that came with the dishwasher.
  3. Clear the sink cabinet so we can reach the taps and the sink waste.
  4. Check for a power point within reach of the dishwasher’s cord. A new power point is a job for an electrician.

Signs the old connection needs work

  • An isolation valve that’s stiff or won’t turn off
  • A rusty, kinked or bulging flexi hose
  • Water under the sink or around the dishwasher
  • A sink that gurgles when the dishwasher drains
  • Dirty water backing up into the sink
  • No isolation valve at all

After-hours call-out fees vary based on the day, time and location.

Why people call Tap Doctor to install a dishwasher

A dishwasher connection that weeps slowly can ruin a cabinet floor before anyone notices. This is how we handle every install.

  • Licensed plumbers

    Every job is done by a licensed plumber, and Tap Doctor is fully licensed and insured.

  • A firm price before any work starts

    Your plumber looks at the space and the connections, explains what’s needed and gives you a firm price. Nothing starts until you agree.

  • No call-out fee in business hours

    You don’t pay for us to turn up and look. If you decide not to go ahead, you owe nothing during business hours.

  • We call ahead and arrive on time

    We confirm your booking, then call before we arrive so you’re not waiting at home all day.

  • Tools and parts on the van

    Our vans carry the tools and common parts for dishwasher installs, so most jobs are finished in one visit.

  • Pay when the job is done

    Cash, card or Osko bank transfer, collected when the work is finished.

How pricing works

What a dishwasher install costs depends on what’s already there. Swapping a dishwasher onto existing connections is a smaller job than adding a new water point and drain to a kitchen that never had one, so instead of guessing over the phone a licensed plumber looks first and agrees a firm price with you on site before any work starts.

No call-out fee in business hours

You only pay for the work you agree to, and there’s no obligation to go ahead. After-hours call-out fees vary based on the day, time and location.

Firm price agreed on site

The price is agreed before we start. If we find something else that needs doing, we quote it before any further work is done.

How you can pay

Cash, credit card or debit card, or bank transfer with Osko for an instant payment. Payment is collected when the job is done.

How to choose a dishwasher installer

Dishwasher installation FAQs

Do I need a plumber to install a dishwasher?

If there’s already a dishwasher tap and drain point in the right place, connecting a new dishwasher is a short job. If a water supply, isolation valve or drain connection has to be added or moved, that’s plumbing work for a licensed plumber.

Can you install a dishwasher where there wasn’t one before?

Yes. We add the water supply, isolation valve and drain connection under the sink so a kitchen that never had a dishwasher can take one. If the cabinet needs cut-outs for the hoses, we do that too.

Do you remove the old dishwasher?

Yes. When you’re replacing a dishwasher, we disconnect and remove the old one before the new one goes in.

Can you install an integrated or built-in dishwasher?

Yes. We fit integrated and built-in dishwashers into the cabinetry and connect the water and drain. If you’re renovating, we can work with your cabinet maker so the plumbing is in the right place.

Does a dishwasher connect to hot or cold water?

Most dishwashers connect to the cold water supply and heat their own water, though some models can take hot. Check the installation guide that came with yours; we connect it the way the manufacturer specifies.

What should I have ready before you arrive?

The dishwasher, its installation guide and the parts that came in the box, a cleared-out sink cabinet so we can reach the taps and waste, and a power point within reach of the dishwasher’s cord.

Can you give me a price over the phone?

It depends on what’s already under your sink, so we don’t guess. A licensed plumber looks at the job and gives you a firm price before any work starts, with no call-out fee during business hours and no obligation.

Do you charge a call-out fee?

Not during business hours. You only pay for the work you agree to. After-hours call-out fees vary based on the day, time and location.

Are your plumbers licensed and insured?

Yes. Every job is done by a licensed plumber, and Tap Doctor is fully licensed and insured.
