About this service
An expansion tank is a small safety device that prevents pressure buildup in your plumbing system as water heats and expands. If your water heater is leaking from the relief valve or your pipes are banging, you may need one installed. This simple addition protects your tank and plumbing from unnecessary stress, extending the life of your equipment. Costs are typically modest. Exact pricing confirmed free on the call.
While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.
