Why So Many El Mirage Water Heaters Are Failing Now
Most El Mirage homes went up in a short window during the 2000s, and builders installed similar tank water heaters in nearly every garage. Those original tanks were mostly replaced by the mid-2010s. Now, many of those second tanks are wearing out too.
In El Mirage, water heaters face the same two enemies as the rest of the West Valley. Hard water leaves sediment in the bottom of the tank that makes the heater less efficient and eventually damages it. And summer garage heat stresses relief valves and gas controls.
Alex & Bros Plumbing is based in nearby Peoria. Alex looks at your water heater, tells you straight whether it is worth fixing, and gives you the price up front.

The Expansion Tank Question
Many El Mirage homes have a pressure reducing valve or a check valve on the main water line, which creates what plumbers call a closed system. When water heats up, it expands, and in a closed system that extra volume has nowhere to go. Pressure spikes, and the relief valve on the water heater may drip or the tank may wear out faster.
An expansion tank gives that water a place to go. It is a small tank mounted near the water heater. If your system needs one and does not have one, we will recommend it and explain why. It is not an upsell. It protects the new heater you just paid for.
More on this and on tankless options is on our main water heater page.

A Tip for El Mirage Landlords
If you own a rental in El Mirage, the water heater is one of the most common emergency calls. Replacing an aging tank on your schedule, between tenants or before summer, costs less and causes less trouble than an emergency swap after it floods the garage. Ask us for a quick condition check next time we are out.

Tank to Tankless in El Mirage
El Mirage homes built in the 2000s usually have the water heater in the garage with natural gas or electric service. For gas homes, switching to tankless is often doable. Here is what we look at:
Gas line size. Tankless units need more gas at once than a tank. Some homes need a larger line from the meter.
Venting. Tankless heaters use a different vent than tanks. We plan the vent route through the wall or roof.
Water quality. El Mirage’s hard water scales up tankless heat exchangers, so we recommend a water softener or regular descaling.
Hot water demand. We size the unit for how many showers and appliances run at once.
For electric homes, whole-house electric tankless units need a lot of electrical capacity, so a new tank or a heat pump water heater is often the more practical choice. We will give you a straight answer on what works.
