Description

Fluidmaster PRO45K Complete Toilet Repair Kit

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.


Key Features & Benefits
  • PRO45 Anti-Siphon Fill Valve: Fluidmaster's quietest fill valve delivers whisper-quiet tank refills and features an adjustable height to fit any tank configuration. The new, easier-to-turn water level dial means you can fine-tune the fill level in seconds, reducing water waste and preventing overflow.
  • PRO57K Flush Valve Kit with Non-Adjustable Flapper: The 3-inch flush valve includes a non-adjustable flapper engineered for consistent, reliable flushing performance. This kit also includes brass tank-to-bowl bolts (two-bolt configuration) and gaskets, eliminating leaks where the tank meets the bowl.
  • PRO61 Adjustable Tank Lever: The adjustable arm length accommodates various toilet handle placements and can be configured for left- or right-handed flush. This metal lever delivers years of dependable operation without the flex or breakage common in plastic handles.
  • Universal Fit, All Brands: This repair kit is engineered to fit every major toilet brand and model, so you can stock one SKU and service any toilet in your facility or job site.
  • Complete Kit for Total Overhaul: Every component for a full internal tank rebuild ships in one package, eliminating multiple trips to the supply house and ensuring all parts are manufacturer-matched for peak compatibility.
  • 5-Year Warranty: Fluidmaster backs the PRO45K with a 5-year warranty, providing long-term peace of mind for both professional installers and end users.

Compatibility & Requirements

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 & Care

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.


What's Included
  • PRO45 anti-siphon fill valve with adjustable height and new easy-turn water level dial
  • PRO57K flush valve kit with 3-inch valve body, non-adjustable flapper, and hardware
  • Two brass tank-to-bowl bolts with washers and gaskets
  • PRO61 adjustable tank lever
  • Tank-to-bowl gasket
  • Printed installation instructions

Warranty & Support

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. For warranty service or technical support, contact Fluidmaster directly through their customer service channels listed in the included documentation.


Frequently Asked Questions

Q: What is the most common problem associated with Fluidmaster toilet repair kits?

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.


Q: How to install a Fluidmaster PRO45K toilet repair kit?

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.

Toilet Rebuild

This is the perfect Toilet Repair Kit. All components are included for a complete rebuild of your existing toilet. The only re-used part is your porcelain. Easy to follow instructions and works like a charm! I was so excited with my first experience that I decided to rebuild all 3 toilets in my house. I feel great knowing the toilets will be fine for many years to come!!! Now onto the next project..............

Photo shows 3-bolts, ships w/ 2

Kit is fine, but PEX photo shows 3-bolt tank to bowl kit, but they ship the 2-bolt kit. Had to run to store for extra bolt kit.

The only toilet rebuild kit I use for all my jobs

Works great when doing a complete rebuild, just know that you may need to get a third brass bolt if your tank to bowl has three bolts instead of two. You can also reuse the old hardware but I recommend using new hardware. FLUIDMASTER also makes a brass bolt kit you can purchase for this reason.

It contains a 400A fill valve, 507 series flush valve, and adjustable 502 model flapper, 681 tank lever and nuts, bolts and gaskets. The PRO45K includes a pro45 fill valve, 507 flush valve, a non adjustable 504 series flapper, 681 tank lever and nuts, bolts and gaskets.
