Protect Your Water Supply with Certified Backflow Prevention

Clean water is the foundation of a healthy home and business. At GreenLine Plumbing & Drain Nepean, we specialize in advanced backflow prevention services designed to eliminate contamination risks.

A sudden drop in water pressure can cause dangerous non-potable water to siphon back into your clean supply. Our fully licensed team ensures your property remains compliant with Nepean safety regulations and your water remains pure.

Comprehensive Backflow Testing & Installation Services

We provide end-to-end solutions for cross-connection control. Whether you manage a commercial facility requiring mandatory annual reporting or a residential property needing updated protection, our specialists handle it all. From the initial installation of a backflow preventer to routine testing and emergency repairs, GreenLine Plumbing & Drain Nepean is your partner in water safety.

Annual Backflow Testing in Nepean

Backwater Valve Installation: Defense Against Basement Flooding

While backflow preventers protect your drinking water, a backwater valve protects your home from municipal sewer backups during heavy storms. This device is your first line of defense against sewage flooding your basement.

Consider pairing this with our Sump Pump Services for a complete flood-protection system.

Device Repair and System Maintenance

Mechanical devices wear down over time due to water pressure and mineral buildup. If your unit fails a test or starts leaking, our team provides rapid backflow preventer replacement and repair services.

For certified backflow prevention, testing, and expert advice, trust the local plumber in Nepean.

Harper J.

I had no idea what to do because pur main line was totally frozen, so I called GreenLine Plumbing. They arrived in like 30 minutes, checked everything and explained why exactly that happened (actually the pipe had frozen and cracked in a small section)...so the plumber replaced the damaged section and insulated the pipes and even and tested the system before leaving. The price was more than OK, even lower than I expected..! Thnks

When our irrigation system lost pressure, I needed well pump service near me urgently. The team was prompt, fixed the pump efficiently, and even gave tips to keep it running smoothly. Saved our crops—thank you!

Our kitchen sink drain was clogged with grease and food debris for some time, and chemical methods did not work at all. The plumber cleared the drain and flushed the pipes. The price was really reasonable.

Well, our sewer smelled terrible and the basement floor drains were slow. So we called them to clear everything. No more odours, and the drains flow perfectly.

Our faucet started dripping constantly, and the handle got really stiff. The plumber replaced the worn cartridge and seals the same day..
