The water in the shower is either hot or cold; I cannot get any temperature in-between. What’s wrong?
Some would blame mischievous water gremlins. But not us. We would theorize that mineral deposits have built up around the spool and sleeve (the part of the Scald-Guard pressure balance valve that blends the hot and cold water). And a buildup like that could interfere with the valve’s proper operation. To solve this problem, follow the steps below (based on your model). Tools you may need before starting: • Shut off the water supply. • Remove the handle. • Twist and pull sleeve to remove it. • Unscrew brass bonnet nut. • Remove the cartridge. • Soak the cartridge in a solution of 50% vinegar and 50% water for 24 hours. This should remove any mineral deposits. • Re-install cartridge and other parts, cross fingers, and test. NOTE: Unless both the hot and cold water supplies are turned on, the pressure balance valve will allow only a dribble of water to flow through the valve.
