Pride Plumbing was called out for a Gerber pressure assist toilet tank that would run constantly and not fill. Our inspection determined that the tank’s Flushmate pressure assist cartridge was malfunctioning. After turning off the water and draining the tank, we used a Flushmate C-100500-KIT and replaced the pressure assist cartridge assembly. We then turned the water back on, refilled the tank, and tested for leaks and proper operation with no issues.
