Expert Expansion Tank Installation in Cherokee County, GA

Expansion tank installation protects your Cherokee County home's plumbing from pressure damage caused by thermal expansion. When your water heater heats water, that water expands. In a closed plumbing system, which is common in Cherokee County homes with backflow prevention devices or pressure-reducing valves, that expanded water has nowhere to go. Pressure builds inside your pipes, water heater, and fixtures. An expansion tank absorbs that excess pressure before it causes damage. At MHR Water Heaters and Plumbing, we assess your system, select the correctly sized tank, mount it to the cold water line near your water heater, and calibrate it to the right pressure. Georgia Plumbing Code requires thermal expansion control in closed systems, so proper installation also keeps your home code-compliant. Many Cherokee County homes built or updated in recent years already have the backflow devices that trigger this requirement. If you are replacing a water heater or had a new meter installed, an expansion tank may be required. Call MHR Water Heaters and Plumbing to schedule your installation.

Expansion Tank Installation FAQ

Common questions about expansion tank installation in Cherokee County, GA.

Your home needs an expansion tank if it has a closed plumbing system, such as one with a backflow prevention device or a pressure-reducing valve. Many Cherokee County homes with updated water meters or newer plumbing already qualify.

Without an expansion tank, excess pressure can damage your water heater, burst pipe fittings, and wear out appliances faster. It can also put your home out of compliance with Georgia Plumbing Code.

Yes, we install expansion tanks as part of water heater replacements and as standalone installations for existing systems in Cherokee County.

The tank mounts on the cold water supply line near your water heater. It must be bracketed or braced to meet Georgia Plumbing Code, not supported by the pipe alone.

Signs of a failed expansion tank include fluctuating water pressure, a T&P relief valve that drips or discharges repeatedly, and knocking sounds in your pipes. Contact MHR Water Heaters and Plumbing for an inspection.

No, they are two different components. Georgia Plumbing Code is clear that a T&P relief valve cannot be used to control thermal expansion in Cherokee County homes with closed systems.

I requested a water heater installation through Angi's List at 6:00 a.m., and within five minutes they contacted me, requested photos, and provided a quote. They came out the same day, resolved the issue quickly, and were professional, knowledgeable, and efficient. I highly recommend their service.

Our water heater quit working over the 4th of July weekend. Phil from MHR responded right away to my request and called me on the holiday to help me troubleshoot the issue over the phone. He was able to diagnose the problem based on the control panel lights and knew exactly what replacement part was required. He also informed me that because it was a common issue with the type of water heater we had, that part was on backorder by the manufacturer for at least two weeks. Understanding that most families with children are likely to struggle for two weeks without hot water, Phil went to bat for us and was able to negotiate a full replacement of our water heater with a newer model that is less prone to the same issue. Even when the manufacturer charged him more for the new unit than the warranty covered for our existing unit, he ultimately honored the original estimate he provided. Integrity is valuable to him as it is to me and he truly demonstrated this with the way he handled our situation.
