Commercial Plumbing in Perth
When a plumbing problem hits a business, it's rarely just an inconvenience — it's closed toilets, a flooded storeroom, a kitchen that can't trade, or tenants ringing the strata manager. Commercial plumbing needs a plumber who understands compliance, works around your operating hours, and turns up when they say they will. Our licensed Canning Vale plumbers look after offices, retail, strata, hospitality and light industrial premises across Perth's south-east.
The stakes are simply higher in a commercial setting — downtime costs money, and there's compliance to stay on top of that most homes never deal with. Having a plumber who gets that makes a real difference to how smoothly your premises run.
Who we look after
Commercial plumbing covers a lot more than a bigger version of a home. Different property types come with different requirements, and we work across the range:
- Offices and commercial buildings — bathrooms, kitchenettes, hot water and drainage
- Retail and shopping strips — fit-outs, tenancy changes and ongoing repairs
- Strata and body corporate — common-property plumbing, shared services and coordinated maintenance
- Hospitality — cafes, restaurants and pubs with grease traps, commercial kitchens and high-demand hot water
- Medical, dental and childcare — premises with strict backflow and hygiene requirements
- Light industrial and warehouses — amenities, drainage and trade waste
Compliance is the difference
The biggest thing separating commercial from domestic plumbing is compliance, and in WA that's not optional. Two requirements come up constantly, and both can trip up a business owner who isn't expecting them:
Backflow prevention
Most commercial properties need testable backflow prevention devices to protect the Water Corporation supply from contamination, and those devices must be tested every year by an endorsed plumber. We install, test and certify them, and lodge the paperwork so you're not caught out by a compliance letter or a missed deadline. There's more detail on our backflow prevention page.
Tempering and thermostatic mixing valves
Premises like childcare centres, aged care, medical facilities and many public washrooms are required to deliver hot water at a controlled, safe temperature to prevent scalding. That's the job of tempering valves and thermostatic mixing valves (TMVs), which also need regular servicing to stay within tolerance. We install and maintain them so your premises stay both compliant and safe for the people using them.
Fit-outs and tenancy changes
When a tenancy changes hands or a business fits out a new space, the plumbing often needs reworking — new kitchenettes, bathrooms, sinks, and appliance connections. We handle commercial fit-out plumbing from rough-in through to fit-off, working to your program and coordinating with builders and shopfitters. Getting it right the first time means fewer callbacks once you're trading and less risk of a leak surfacing after opening day.
Maintenance contracts that prevent problems
For most businesses, the smartest approach is preventive rather than reactive. A planned maintenance contract means we regularly check the plumbing that matters — hot water systems, backflow devices, tempering valves, drains, grease traps and fixtures — and fix small issues before they become a trading-day disaster that costs you customers.
- Scheduled inspections and servicing on a cycle that suits you
- Backflow and tempering valve testing kept up to date automatically
- Drain maintenance to prevent blockages in high-use kitchens and amenities
- Priority response when something does go wrong
- One point of contact who knows your site and its history
For a strata or multi-tenancy, that consistency is invaluable — the same plumber who knows where the isolation valves are and what's been done before, rather than starting from scratch every time.
Hot water sized for the demand
Commercial hot water is a different beast to a home system. A busy cafe, a hairdresser, or an office with a full kitchen can chew through hot water in a way a household never does, and an undersized or poorly maintained system means cold taps at the worst moment. We size, install and maintain commercial hot water to match your actual demand, whether that's continuous flow units for point-of-use, larger storage systems, or a bank of units for a bigger site. Keeping it serviced also keeps running costs down, since a scaled-up or struggling system quietly burns more energy than a well-maintained one.
When something goes wrong
Even with good maintenance, emergencies happen — a burst pipe over a weekend, a blocked drain shutting a kitchen, a hot water failure before a busy service. Downtime costs money, so we prioritise commercial emergency plumbing to get you trading again fast. For persistent drainage issues in busy hospitality kitchens, our CCTV drain inspection and hydro-jetting gets to the root of the problem rather than repeatedly clearing the same blockage every few weeks.
Local, licensed and reliable
Being based in Canning Vale, we're well placed to service businesses across Thornlie, Willetton, Riverton, Southern River, Harrisdale, Gosnells and the wider south-east — and we're close enough to respond quickly when it counts. All work is carried out by licensed, insured plumbers, with upfront pricing and clear documentation, which matters when you're managing a property or answering to a body corporate that expects paperwork.
Whether you need a one-off repair, a full fit-out, or a maintenance contract that takes plumbing off your worry list, we can help keep your premises running.
Documentation you can hand over
One thing that separates a good commercial plumber from a cheap one is the paperwork. Property managers, strata committees and business owners often need to prove work was done, compliance was met, and testing is up to date — whether for an audit, an insurer, or an incoming tenant. We provide clear documentation for the work we carry out, keep your backflow and tempering valve testing records current, and give you the certificates and reports you need on file. When it comes time to answer to a body corporate or renew a lease, having that trail already in order saves a scramble and shows the premises has been properly looked after.

Frequently asked questions
Does my commercial property need backflow testing?
Most do. Water Corporation requires testable backflow prevention devices on commercial, medical, hospitality and many other premises to protect the drinking water supply, and they must be tested annually by an endorsed plumber. We install, test, certify and lodge the paperwork so you stay compliant.
What are tempering and thermostatic mixing valves, and do I need them?
They control hot water temperature to prevent scalding. Premises like childcare, aged care, medical facilities and many public washrooms are required to have them, and they need regular servicing to stay within tolerance. We install and maintain them to keep your premises safe and compliant.
Can you work around our trading hours?
Yes. We understand downtime costs money, so we schedule non-urgent work to suit your operations and prioritise emergencies to get you trading again fast. For strata and multi-tenancy sites, having one plumber who knows the property makes coordination much easier.
Do you offer maintenance contracts?
We do. A planned maintenance contract keeps your hot water, backflow devices, tempering valves, drains and grease traps checked on a regular cycle, catches small issues early, and gives you priority response. It's the most cost-effective approach for most businesses and strata.
