Short answer
Low water pressure in one fixture is usually a clogged aerator or cartridge; low pressure throughout the house points to a failing pressure regulator, a leak or scale-choked galvanized pipe. High pressure above about 80 psi strains pipes and appliances. Call (857) 201-2772 to test the pressure and find the cause.

Water pressure repair in Phoenix and across Arizona
Pressure that is too low makes showers weak. Pressure that is too high wears out valves, toilets and supply lines and can void appliance warranties. A pressure-reducing valve near the main controls it in most Arizona homes.
We take water pressure repair calls in Phoenix and in cities across Arizona, from Mesa, Chandler and Scottsdale to Tucson, Flagstaff and Yuma. The quickest way to start is to call (857) 201-2772 and describe what you are seeing. A person answers and talks you through what to do right away, and you get a written quote before any work starts.
What are the signs you need water pressure repair?
- Weak showers and slow-filling toilets
- Banging pipes (water hammer)
- Pressure that changes through the day
- Running toilets and dripping relief valves
- A reading above about 80 psi at a hose bibb
If more than one of these sounds familiar, do not wait for it to get worse. Water damage, mold and higher bills grow quickly, and small repairs often turn into large ones when they are put off. If water is actively leaking, close the main shutoff valve first, then call.

Why do Arizona conditions matter for water pressure repair?
City pressure varies a lot across the Valley, especially near hills and at the edge of pressure zones. Galvanized pipe in older homes scales shut from the inside and drops flow.
Arizona water is hard almost everywhere, from Phoenix to Tucson and Yuma. Utilities such as Phoenix Water Services publish yearly water quality reports showing what is in your supply, and the Central Arizona Project delivers Colorado River water to much of central and southern Arizona. That mineral load is behind a lot of early water heater failures, crusted fixtures and narrowed drains. Low-desert heat is hard on garage and attic plumbing, while high-country cities face winter freezes.

Call (857) 201-2772What should you check before you hire a plumber?
In Arizona, the Registrar of Contractors oversees contractor licensing. Use the Arizona Registrar of Contractors contractor search to check any plumber's license status and complaint history before you hire. Ask for a written scope and price, ask what permits the job needs in your city, and keep the paperwork. Permits for major work such as repipes, sewer replacements and water heater changes are handled by your city or county building department.

What should you do before the plumber arrives?
- Find the main water shutoff, usually in a box near the street or on an outside wall, and know how to close it.
- If a water heater is involved, turn the gas valve to pilot or off, or switch off its breaker.
- Move valuables and rugs away from any leak, and take photos for your records or insurer.
- Clear access to the area: under the sink, the water heater closet, the yard cleanout or the attic hatch.
- Write down when the problem started and anything that changed, such as a new appliance, a recent freeze or a monsoon storm.
These steps limit damage and make the visit faster. When you call (857) 201-2772, we will tell you which of them matter most for your situation.
