Important Note: Pressure Balancing Valves, regardless of brand, are generally not recommended for use with tankless (on-demand) water heaters. Pressure Balancing Valves adjust to the lowest incoming water pressure. Because outgoing hot-water pressure of tankless water heaters can sometimes be significantly lower than household cold-water pressure, the result can be unsatisfactory water pressure in the shower.
