TPR Valve Replacement
The T&P valve opens around 210°F or 150 psi — it is the tank's last line of defense. We find out whether a dripping valve is worn out or warning you…
The pressure shock absorber
The expansion tank is a small tank with a big job: absorbing the pressure spike every time your heater warms a full tank of water in a closed plumbing system. When its internal bladder fails, every heating cycle becomes a pressure hammer — popping the T&P valve, straining fittings, and creating leaks all over the system. We test bladder integrity and air charge, replace failed tanks, and set the new tank's pre-charge to match your home's static pressure. Certified Professional, Licensed & Insured Team.

About this service
Here is the maintenance angle most homeowners miss: a dead expansion tank doesn't just sit there — it actively creates leaks elsewhere. The T&P valve starts discharging after every heating cycle, fittings that were fine begin to weep, and the water heater takes the blame for a system-wide pressure problem. We check the tank with the tap test and a pressure gauge, and if the bladder has failed, it gets replaced with the air charge set to match your home's actual static pressure — not a guess.
Serving Wheaton, IL 60187 and nearby neighborhoods. The yearly habit we leave you with is simple: tap the tank once a year (it should sound hollow, not solid or sloshy) and keep an eye on your home's pressure — normal is 40 to 60 psi, and 80 or above is high enough to act on. Call (833) 713-2101 and we will check yours.

How it works
We close the water supply to the heater and relieve system pressure before servicing the tank.
We tap-test the tank, check its air charge with a gauge, and measure your home's static water pressure.
We explain whether the bladder failed, whether the pre-charge was wrong, and what the replacement involves.
The failed tank is replaced and its air charge is set to match your home's static pressure, then the system is tested.
We show you the annual tap test and what pressure readings to watch, so the next failure announces itself early.
FAQ
It gives heated water somewhere to go. In a closed plumbing system, warming water expands and pressure spikes; the expansion tank's air bladder compresses to absorb it. Without a working tank, that spike hits your T&P valve, fittings, and appliances instead.
The classic signs: the T&P valve discharging after heating cycles, water hammer, or pressure readings that swing wildly. The tap test is the quick check — a healthy tank sounds hollow at the top; a failed one sounds solid or sloshes.
Absolutely — it is one of the most common hidden causes of repeat leaks. Every pressure spike stresses fittings, valves, and supply lines across the system. Fixing the 'leak' without fixing the failed tank just schedules the next callback.
