Commercial plumbing

A commercial plumber that picks up.

Restaurants, retail centers, office buildings and manufacturing facilities across the West Valley. 24/7 emergency service, certified backflow testing, and a real person on the line.

Who calls, and who picks up

Sunstate Plumbing, Inc is a family-owned, locally operated shop at 8701 N 78th Ave in Peoria, and its commercial work covers restaurants, retail centers, office buildings and manufacturing facilities across the West Valley and the rest of Greater Phoenix. The accountability is the same whether the job is one restroom or a whole facility: one crew that learns the building, and one number to call, (623) 937-4258.

What separates us from the larger commercial plumbing companies is plain. When you call, a real person answers. There is no answering service, no voicemail routing and no callback queue standing between you and the shop. That matters when a line lets go at 2 a.m., when a floor drain backs up in a kitchen with a health inspection on the calendar, or when one broken restroom is the only thing keeping a tenant from opening the doors.

Emergency commercial service runs 24 hours a day, seven days a week. The office keeps Monday to Thursday 8 AM to 4 PM and Friday 8 AM to 2 PM, but the phone does not stop at four. Work that is not an emergency can often be scheduled the same day, and a satisfaction guarantee stands behind it. Ask about warranties on your specific job when you call.

Backflow: inspect, repair, re-test

A backflow prevention device sits on a commercial property's main water connection and keeps whatever is on your side of the meter from drifting back into the public water supply. Commercial properties may be required by law to have one. Arizona state law may require annual testing of backflow prevention assemblies by a certified tester, and Glendale's City Water Services may require that test results be submitted to the city on a regular basis.

Sunstate is a certified backflow tester, so the company that tests the assembly is the same one that fixes it. Inspection comes first: the assembly is isolated and run through its test to see whether the check valves hold and the relief valve opens when it should. If something fails, diagnosis comes before repair, because a fouled check and a worn seat are different jobs. Maintenance keeps the device in compliance between tests, and re-test support confirms a repaired assembly now passes.

Because one company handles every stop on that run, you have a single point of contact for compliance year after year, and no gap while a failed device waits on a second contractor. Properties in Peoria and Glendale get the same routine: test it, fix what failed, test it again. The four stops are drawn out just below.

Codes, inspectors and downtime

Commercial permitting is where good schedules go to wait. Our crew knows the local codes and has working familiarity with Glendale inspectors, which can help keep a commercial project moving through permitting without unnecessary delays. Knowing what an inspector will look for before the inspector arrives is most of the work: how a line is supported, where the cleanouts fall, how a backflow assembly is set.

Downtime is the other half. A restaurant cannot lose water through a lunch rush, and an office building cannot lose every restroom on a Monday morning. Before a valve closes we talk through which lines come down, for how long, and which fixtures stay in service, so the plan is yours to approve and not a surprise at the door.

That is why the first call matters. Describe the building, the problem and the clock you are under, and the person on the line is the one who knows the shop's schedule. Call (623) 937-4258 from Peoria, Glendale or anywhere else in the West Valley.

Four kinds of building

Who we plumb for

Restaurants
Floor drains, grease-prone lines and hand sinks, with a health inspection date setting the clock.
Retail centers
Shared supply and drain lines that serve several tenants, so one leak is never only one tenant's problem.
Office buildings
Restrooms, break rooms and water heaters that a whole floor of people depends on by 8 a.m.
Manufacturing facilities
Floor drainage and water lines where a shutoff has to be planned around the production day.

The backflow cycle

Arizona may require testing every year, so the run closes on itself: after the re-test, the next annual inspection is already the next stop.
