Phoenix plumbing deals with very hard water and extreme heat. Minerals build up as scale in pipes, fixtures and water heaters, slab leaks are common in homes built on concrete, and summer heat stresses pipes and equipment in attics, garages and outdoor spaces.
Sifixit is a free referral service. Call the number on this page and you will be connected with an independent plumbing provider that serves the Phoenix area, where one is available for your ZIP code. Calling costs nothing and you are never obliged to hire anyone.
Common plumbing problems in Phoenix
Very hard water
Phoenix water is very hard, leaving mineral scale that clogs aerators, shower heads and water heaters.
Water heater wear
Scale settles in tank water heaters, which makes them work harder and wear out sooner.
Slab leaks
Most homes sit on concrete slabs, and leaks in pipes beneath them can go unnoticed for a long time.
Heat
Extreme summer heat stresses pipes and equipment in attics, garages and outdoor spaces.

Permits and local rules
Cleanup itself does not usually need a permit, but the repairs that follow often do. Inside the city of Phoenix, larger drywall, electrical and plumbing repairs can require permits from the City of Phoenix Planning and Development Department. Homes in other cities, such as Scottsdale, Tempe or Mesa, follow the rules of that city or county.
In Arizona, contractors must be licensed by the Arizona Registrar of Contractors, and you can check a license online.
Seasonal risks in Phoenix
If you smell gas, leave the home and call 911 or your gas company from outside. If water is near electrics, stay out of it.
- Summer: heat strains water heaters and outdoor plumbing.
- Monsoon season: heavy rain can overwhelm drains.
- Winter: rare freezes can crack outdoor pipes.
- All year: hard water scale builds up.
Be prepared
- Flush your water heater once a year
- Consider a water softener to reduce scale
- Clean aerators and shower heads regularly
- Watch for warm floor spots or a rising water bill
- Cover outdoor pipes and backflow devices on rare freezing nights
