The FLUIDMASTER INC 400CRP14 is an adjustable toilet tank repair kit designed to address the two most common toilet problems: faulty fill valves and worn flappers. Each kit includes a 400A fill valve and a 501 Dura-Flush flapper. The fill valve is adjustable to fit a range of tank configurations, and the flapper is manufactured to resist chlorine degradation, making it suitable for use in areas with harsh or treated water supplies. This kit is packaged in a quantity of 14 units per case, making it well-suited for plumbers and maintenance professionals stocking supplies for multi-unit jobs or service routes.
This repair kit is intended for residential and light commercial toilet tank service. The 400A fill valve and 501 Dura-Flush flapper address the most frequent causes of running or slow-filling toilets. The chlorine-resistant flapper is a practical choice in municipalities or regions where water treatment levels are elevated. Plumbing contractors, property maintenance technicians, and service plumbers handling volume repair work will find the 14-unit case count useful for keeping common repair components on hand.
Designed as an OEM-style replacement kit for standard residential and light commercial toilet tanks requiring fill valve or flapper service.
Installation is performed by a licensed plumber or experienced maintenance technician. Shut off the water supply at the angle stop valve below the tank and flush to empty the tank before beginning any repair. Follow local plumbing codes and the manufacturer instructions included with each kit when setting fill valve height or seating the flapper. Do not overtighten the fill valve locknut against the tank.
