Why Avondale Water Heaters Quit in Summer
It surprises people that water heaters fail most often in the hottest months, but it makes sense. Avondale garages turn into ovens from June through September. That heat stresses relief valves, gas controls, wiring and any plastic parts. A tank already weakened by years of hard water sediment is more likely to give out when that heat hits.
The most common Avondale call we get in summer is a tank leaking from the bottom. That means the tank has rusted through, and it needs replacing.
Alex & Bros Plumbing is a family-owned company from Peoria. When you call, you get Alex. He will tell you whether it is repairable or needs replacing, and give you the price before any work starts.

For Avondale Landlords
Water heater failures are among the most common rental emergencies. If your rental’s heater is over ten years old, replacing it between tenants or before summer is cheaper and easier than an emergency call. We give clear invoices and work with property managers.


Expansion Tanks and Relief Valves in Avondale
A lot of Avondale homes have a pressure reducing valve at the main line, which makes the plumbing a closed system. When a water heater heats water, it expands, and in a closed system that extra volume has nowhere to go. Pressure spikes each time the heater runs.
Over time, those spikes wear out the tank and can make the temperature and pressure relief valve drip or discharge. People sometimes cap a dripping relief valve line to stop the mess, which is dangerous. That valve is the last safety device on the tank.
An expansion tank absorbs the extra volume and keeps pressure stable. If your system needs one and does not have one, we recommend it when we service or replace the heater. We also make sure the relief valve drain is piped to a safe spot.
Reviews From Homeowners Near Avondale
I highly recommend Alex for any plumbing needs! From start to finish, he provided exceptional service. He was courteous, professional, and genuinely took the time to explain everything clearly.

Great experience. Provided some good info to help me decide what I need, info the other quoters missed. Price was good compared to the others, and included labor warranty to match the water heater warranty. Will definitely call them next time I need plumbing help.
