We tell you what we can do, when we can do it, and what it will cost before we start.

Why do freezes, elevation and winter plumbing matter in Prescott?

A large share of homes here were built before 1980, so original galvanized supply lines, cast-iron drains and clay sewer laterals are still common. Those materials narrow, corrode and let roots in, which shows up as low pressure, rusty water and repeat main line clogs.

Water heaters in Prescott: repair or replace?

Water heaters are the most common reason Prescott homeowners call. Prescott pumps groundwater from the Chino Valley area. Hard freezes, old galvanized lines in downtown homes and long winter vacancies cause much of the trouble. Scale shortens tank life, so a heater that might last well over a decade elsewhere often needs replacing sooner here. Popping noises, rusty hot water, a leaking relief valve or water at the base of the tank are all signs it is time to look at it.

If the tank is sound and the problem is a part such as a thermocouple, gas valve, element or thermostat, a repair usually makes sense. If the tank is leaking, it needs replacing. Before you call, try our water heater replacement cost calculator to see a typical installed range for tank, tankless and hybrid heat pump units. Then call (857) 201-2772 for an exact quote for your Prescott home.

How do you find a hidden or slab leak in Prescott?

A sudden jump on your water bill is often the first sign of a hidden leak. To check, turn off every fixture, the irrigation controller and the pool fill, then watch the meter. If the small leak indicator still moves, water is going somewhere. In Prescott the usual suspects are irrigation lines, toilet flappers, pool auto-fill valves and supply lines under the slab. Our leak detection service narrows it down before anything is opened up. If the leak is under the floor, slab leak repair covers spot repair and rerouting. For houses with repeated leaks, a repipe is often the better long-term fix.

What causes drain and sewer backups in Prescott?

A single slow sink is usually a local clog. When the lowest shower backs up as the washer drains, or several fixtures gurgle at once, the main line is the problem. In Prescott, roots from irrigated trees, grease, scale and sagging sections of older lines cause most main line backups. We clear lines with a cable or a hydro jetter, and when clogs keep coming back we recommend a camera inspection to see what is really going on before you pay for a sewer line repair. Sewer repairs that need a permit go through the City of Prescott.
