What We Do

Our Commercial Plumbing Services

A full range of commercial plumbing and gas services designed to keep your business compliant, efficient, and operational – backed by our fixed-price guarantee and workmanship warranty.

Commercial Hot Water Systems

From high-capacity gas and electric systems to solar and heat pump solutions, we install, repair, and maintain commercial hot water systems for hotels, gyms, hospitals, and multi-tenancy buildings. We work with all major brands including Rheem, Rinnai, and Bosch.

Commercial Gas Fitting & Compliance

Our licensed gasfitters (GF 014602) handle everything from new gas line installations to leak detection, appliance connections, and compliance certificates. We service commercial kitchens, industrial heaters, and gas-powered equipment across all property types.

New Installations & Fit-Outs

Building a new commercial space or renovating an existing one? We provide end-to-end plumbing installation for new builds, office fit-outs, restaurant conversions, and bathroom renovations – from first-fix rough-in to final fixture installation.

Commercial Drain Cleaning & CCTV Inspections

Blocked drains can shut down a commercial kitchen or bathroom in minutes. We use high-pressure hydro-jetting and CCTV drain cameras to clear blockages fast and identify underlying issues like tree root intrusion, pipe collapse, or grease build-up before they become emergencies.

Plumbing Compliance Inspections

Commercial plumbing systems must meet specific WA building codes and Water Corporation regulations. We conduct thorough inspections of your entire plumbing infrastructure and provide a detailed compliance report with recommendations.

Preventative Maintenance Programs

Avoid costly emergency callouts with a scheduled maintenance plan. We offer tailored maintenance programs for commercial properties – regular inspections, drain cleaning, hot water servicing, and system health checks that extend the life of your plumbing.

Common Questions

Frequently Asked Questions About Commercial Plumbing

Got questions about commercial plumbing in Perth? Here are answers to the most common things our business clients ask.

Commercial plumbers are trained to work on larger, more complex plumbing systems found in offices, restaurants, hospitals, and industrial buildings. This includes higher-capacity pipe networks, commercial-grade fixtures, backflow prevention devices, grease traps, and systems that must meet stricter WA building codes. While all our plumbers hold the same WA plumbing licence, our commercial team has specific experience with the scale, regulations, and time pressures involved in business plumbing work.

Commercial plumbing costs vary depending on the scope of work. A routine repair like clearing a blocked drain may cost a few hundred dollars, while a full bathroom or kitchen fit-out for a commercial property could range from $5,000 to $50,000 or more. We provide fixed-price quotes before every job, so you know the exact cost upfront. Our $0 call-out fee during business hours* and free on-site assessment mean there is no cost to find out what your job will cost.

Yes. We provide 24/7 emergency commercial plumbing services across the Perth metropolitan area. Plumbing emergencies like burst pipes, sewage overflows, or gas leaks can cause serious damage to commercial properties and disrupt operations. Our team is available around the clock – including weekends and public holidays – and aims to respond quickly to minimise downtime for your business.

We recommend annual plumbing inspections for most commercial properties. High-use environments like restaurants, hospitals, and aged care facilities may benefit from inspections every six months. Regular inspections catch small issues before they become expensive emergencies, ensure ongoing compliance with WA regulations, and extend the lifespan of your plumbing systems. We offer scheduled maintenance programs tailored to your property type and usage.

Backflow prevention stops contaminated water from flowing backward into the clean water supply. Most commercial properties in Perth are required by the Water Corporation to have backflow prevention devices installed and tested annually. This is particularly important for businesses that use chemicals, food processing, or have irrigation systems. We install and certify backflow devices and provide annual testing to keep your property compliant.

Yes. Grease traps are a legal requirement for most food-service businesses in Perth, including restaurants, cafes, bakeries, and commercial kitchens. We install grease traps that meet your local council’s requirements and provide scheduled cleaning and maintenance to prevent blockages, overflows, and non-compliance penalties. We can also help with the paperwork and council approvals.

Absolutely. Every plumber at Proud Plumbing and Gas holds a current WA plumbing licence (PL 9874) issued by the Plumbers Licensing Board. Our team is fully insured with public liability coverage and undergoes regular training to stay current with the latest plumbing technologies, WA building codes, and safety standards. We provide compliance certificates for all work that requires them.

We service the entire Perth metropolitan area for commercial plumbing, from Joondalup and Wanneroo in the north to Rockingham and Mandurah in the south, and from Fremantle in the west to Midland and Kalamunda in the east. This includes all major commercial and industrial hubs like Perth CBD, Osborne Park, Malaga, Welshpool, Canning Vale, and Balcatta. We offer free on-site assessments across all service areas.

Yes. We conduct thorough compliance inspections covering all plumbing systems on your commercial premises – pipes, fixtures, water systems, drainage, backflow devices, and gas installations. After the inspection, you receive a detailed report outlining any non-compliance issues and our recommendations for corrective action. This protects your business from fines, insurance issues, and workplace safety risks.

For commercial plumbing emergencies, we prioritise rapid response because we understand that downtime costs your business money. In most cases across the Perth metro area, we can have a licensed plumber on-site quickly after your call. Our team operates 24/7, so whether it is a burst pipe at midnight or a gas leak on a public holiday, we are available to respond immediately.
