Dishwasher Installation

Yes. In Queensland, installing a dishwasher is classified as “notifiable work” by the QBCC. This means it must be performed by a licensed plumber who is required to lodge a Form 4 upon completion. Professional installation ensures your appliance meets AS/NZS 3500 standards, which is essential for maintaining your home insurance and manufacturer’s warranty.

Many areas of Brisbane have water pressure exceeding 700kPa, yet most dishwasher manufacturers (like Bosch and Miele) require pressure to be below 500kPa. Operating without a PLV in high-pressure zones can cause internal valves to fail and will almost certainly void your warranty. We test your water pressure during every installation and can fit a high-quality PLV to protect your investment and prevent “water hammer” noise.

This is a common issue in older homes where the drain hose hasn’t been installed with a “High Loop.” Without this loop, dirty water from your kitchen sink can siphon back into the dishwasher, leading to foul odours and unhygienic conditions. Our plumbers ensure every installation features a correctly secured high loop or anti-siphon valve to keep your appliance and your dishes perfectly clean.

Absolutely. If you’re adding a dishwasher to a kitchen that lacks the existing infrastructure, we can “tap into” your existing kitchen sink plumbing. This involves installing a new dual-outlet mini cistern tap and modifying your sink trap to include a dishwasher “spigot.” We provide a fixed upfront price for these upgrades, so you’ll know the total cost of adding the new service before we start.
