The Fluidmaster PRO45K Complete Toilet Repair Kit is an all-in-one solution designed to restore any toilet tank to like-new performance. This comprehensive kit includes everything needed for a total internal rebuild: a PRO45 anti-siphon fill valve (the quietest fill valve on the market), a PRO57K flush valve kit with non-adjustable flapper and tank-to-bowl hardware, and a PRO61 adjustable tank lever. The PRO45K fits all toilet brands and is code-approved, making it the reliable choice for contractors, maintenance professionals, and serious DIYers tackling complete toilet overhauls. With a new, easier-to-turn tank water level adjustment dial on the PRO45 fill valve, setup is faster and more precise than ever.
The PRO45K fits all standard two-piece toilets across every major brand. The PRO45 fill valve adjusts to accommodate tanks of varying heights, and the PRO57K flush valve's 3-inch diameter is compatible with standard flush valve openings. The kit includes a two-bolt tank-to-bowl hardware set. If your toilet uses a three-bolt configuration, you will need to source an additional brass bolt and gasket separately (not included in this kit).
Installation requires basic hand tools and follows standard toilet tank repair procedures: shut off water supply, empty and remove the old tank components, install the new fill valve and flush valve with included hardware, reattach the tank lever, and restore water supply. Detailed step-by-step instructions are included with the kit. No special maintenance is required beyond periodic inspection of the flapper and fill valve for mineral buildup in hard water areas.
Fluidmaster provides a 5-year warranty on the PRO45K Complete Toilet Repair Kit, covering defects in materials and workmanship under normal residential or commercial use.

A: The most common issues involve improper installation or component adjustment rather than product defects. If the tank takes too long to fill or approaches overflow after flushing, check that the PRO45 fill valve's water level dial is set correctly and the PRO57K flapper seats properly on the flush valve. Banging noises from pipes typically indicate water supply line pressure issues, not a fault with the kit itself.
A: Begin by shutting off the water supply and draining the tank. Remove the old fill valve, flush valve, and tank lever. Install the new PRO45 fill valve by threading it through the tank's fill valve opening and securing with the included locknut. Mount the PRO57K flush valve in the center flush valve opening, attach the flapper, and secure the tank to the bowl using the two brass bolts and gaskets provided. Finally, attach the PRO61 tank lever to the flush valve's lift arm and restore the water supply, adjusting the PRO45 water level dial as needed.
