Apartment and Multifamily Plumbing in Phoenix

Arizona's Residential Landlord and Tenant Act is short on plumbing detail, but two duties in A.R.S. 33-1324 carry most of the weight. The owner keeps all plumbing and sanitary facilities in good and safe working order, and supplies running water and reasonable amounts of hot water at all times.

The clock matters. When a plumbing failure materially affects health and safety (no water, no hot water, a sewer backup), A.R.S. 33-1361 lets the resident give written notice that the lease ends in five days if it isn't fixed. Arizona also gives tenants self-help repair rights for smaller problems and specific remedies when water is cut off. So a no-hot-water call on a Friday night isn't a Monday problem. That's the practical case for a plumber who answers 24/7.

Most multifamily calls come from a short list:

• Kitchen drain stacks. In stacked units, every kitchen above shares one drain. Grease from a dozen kitchens coats the stack until the lowest unit's sink backs up with someone else's dishwater. Snaking one unit clears a hole; hydro jetting the stack from a cleanout or roof vent clears the pipe.
• Water heaters. Phoenix water is hard, and scale shortens tank life and slows recovery. Whether you run one heater per unit or a central boiler plant, a flushing schedule and a plan for replacements beats emergency swaps. See how hard Phoenix water is and repair or replace.
• Main building sewers. Roots, sagging clay and old cast iron under the parking lot. A camera run before a refinance or purchase tells you what you're inheriting.
• Toilets and fill valves. One running toilet in a submetered or RUBS property shows up on a resident's bill, and on your water bill if you don't bill back.
• Irrigation and pool backflow. Common-area systems carry assemblies that need a yearly test.

Homeowners in Phoenix get a break: if the sewer line serving a house or duplex breaks in the public right-of-way, the city fixes that section. Apartment owners don't. Under Phoenix City Code 28-5.1, for anything other than a single-family home or duplex, the owner repairs a broken building sewer even when the break is off the property in the street or alley, and pulls a city permit to do it. Here's who is responsible for the sewer line in Phoenix in more detail.

Most repipes, valve swaps and water heater replacements need a building or riser shut down. A good shutoff has written notice, a firm window, a working isolation valve found before the day of the job, and a crew that can restore water if something else turns up. Our guide to planning a commercial water shutoff walks through it. Clean and simple.

Phoenix requires backflow protection on multi-story buildings with booster pumps or above-ground storage tanks, and on irrigation systems, with every assembly tested at least once a year. Missing the test can put the water service at risk, so tie the due dates to your maintenance calendar.

If you bill water back to residents, A.R.S. 33-1314.01 lets you use a submeter or a ratio utility billing system (RUBS), passing through only the utility's charges plus a disclosed administrative fee. See submetering and RUBS in Arizona.
