We have a pretty new (less than 2 years old) hot water heater. Every time someone takes a shower, washes dishes, etc., the tank refills (obviously) but the overflow pipe always ends up dripping. We put a container under the pipe and I would say we are dripping about a pint of water a day. Is this normal? Is there an adjustment that can be made to make it stop refilling before it overflows?
