Our customers aren’t too surprised when they learn that our expansion tanks in Springboro, OH are the best for miles around. The good news is that when we do install a water heater expansion tank, they are very grateful to have it. These customers usually live in older homes whose hot water heaters didn’t come with an expansion tank. Instead, these tanks had a check valve that kept the pressure in the tank from becoming too high. Now they notice that their plumbing fixtures are breaking down, and their water heater’s relief valve is leaking. One remedy for that is an expansion tank.
