Thank you for your question, DReed! A Monitor pressure balance valve keeps water temperature within a safe +/-3degrees F (+/-1.6degrees C), helping to protect you from sudden changes in hot or cold water pressure. Because of this, if you have an on-demand or tankless water heater, it may need to be adjusted so that it activates with less flow. We also recommend lowering the temperature of the hot water in your home if it is above 120 degrees.
Best regards, Edward
