Leaking from the top? Dripping TPR valve? Banging noises? We diagnose and fix expansion tank and pressure issues the same day.
Water dripping from the top of your water heater is not the same problem as water dripping from the bottom. A TPR valve that releases periodically is not broken — but it may be telling you something important about your system pressure. A banging water heater might be a sediment issue, or it might be a thermal expansion problem that's stressing your tank.
The water heater pressure system — the interplay between the thermal expansion tank, the temperature and pressure relief valve, the incoming supply pressure, and the tank itself — is often misunderstood. That's understandable. It's a system most homeowners never think about until something visibly goes wrong.
Bill's Plumbing Services LLC specializes in water heater expansion tank installation, TPR valve diagnosis and replacement, and water heater pressure system troubleshooting across Fort Morgan, CO. We explain what we find in plain terms and fix what needs fixing.
When cold water enters your water heater and heats up, it expands. This is thermal expansion — heated water occupies more volume than cold water. In an older open plumbing system (without a backflow preventer), that extra volume simply pushed back through the supply line into the municipal main. Problem handled.
Modern plumbing systems in Fort Morgan homes — particularly those installed or updated after 2012 — include backflow preventers and pressure regulators at the meter. These are unidirectional. Expanded water can no longer push back into the municipal supply. Instead, it has nowhere to go.
This is called a closed plumbing system. And in a closed system without a thermal expansion tank, every heating cycle puts pressure stress on the water heater tank, the plumbing connections, and the TPR valve. Over time, this either damages the tank fittings, causes nuisance TPR valve releases, or both.
The expansion tank is the solution: it provides a contained air-cushioned space where thermally expanded water can temporarily displace without building destructive pressure in the main system.
In Fort Morgan, CO, homes that had expansion tanks installed when their water heater was replaced are fine — as long as the tank is correctly sized and functioning. Homes that have had backflow preventers or PRVs installed without a corresponding expansion tank installation are operating with a pressure problem they may not yet be aware of.
When water is coming from the top of the water heater, the most common sources are the cold water inlet connection, the hot water outlet connection, or the TPR valve discharge line. We diagnose the specific source before beginning any repair in Fort Morgan homes.
We run a system pressure test to determine whether the valve is operating correctly or worn. Replacing without addressing the cause is avoided in Fort Morgan, CO homes.
We test expansion tank function as part of any water heater service call and recommend replacement when the tank is non-functional.
We install properly sized expansion tanks for your specific system and pressure-test the installed system.
We distinguish between sediment and expansion-related banging in Fort Morgan, CO homes.
Full pressure system assessment including TPR valve function testing, expansion tank condition, and more.
"They did a proper pressure test, found my expansion tank had failed, and replaced it the same day. The TPR valve was fine once the pressure was correct. I appreciated that they didn't just sell me a new valve — they found the actual cause."
"Bill's came out, diagnosed it as a waterlogged expansion tank, replaced the expansion tank, and the noise stopped completely. That diagnostic accuracy saved us a significant amount of money."
The expansion tank: your closed system's shock absorber...
The TPR valve: your last line of defense, not your first...
If your water heater is more than five years old and you've never had the expansion tank tested, it's worth having done. If your TPR valve has ever dripped, a pressure system assessment is the right response.
