What hard water does in your home
Tank water heaters
Minerals settle as sediment at the bottom of the tank. This can cause popping or rumbling sounds, slower heating, and less hot water.
Tankless water heaters
Scale builds up inside the heat exchanger. This can reduce flow and hot water output and trigger error codes.
Faucets and showerheads
White crust on aerators and showerheads, and lower flow.
Fixtures and glass
Spots on glass, shower doors, and dishes.
Dishwashers and washing machines
Mineral buildup inside the appliance.
