Wrench for toilet flush valve nut - multiple sizes available

Wrench for toilet flush valve nut - multiple sizes available
Flush valve assemblies and nuts are shown for illustration purposes only and not included in the sale.
Design
These wrenches are purpose-built for removing and installing the flush valve nut securing the flush valve to the tank on many residential two-piece toilets. The socket applies uniform pressure around the nut to avoid damaging the nut or valve body, and ensures the tank seal is compressed evenly during installation. The sturdy handle provides plenty of leverage to remove old crusty tank valve nuts, and easily tightens the nut to properly compress the new tank seal. Save yourself time, frustration, and extra trips to the hardware store. These wrenches make it easy to perform a quick, leak-free, replacement of a flush valve or tank seal.
Construction Material
All wrenches are made of Marine-grade high density polyethylene (“HDPE”) polymer plastic isextremely durable. The material won't splinter, rot, delaminate, or swell. Simply put, you’re not going to break it!  These tools
are are well suited for frequent use by a professional plumber.
All wrenches are milled from a single piece of material. No joints, ribs, or flashing. All outer edges rounded for user comfort.
Compatibility
The wrench sizes refer to the measured distance across the nut/socket flats. Compatibility with certain toilet brands can be difficult to determine before disassembly.  Be aware that manufactureres typically refer to their flush valve sizes in nominal values. For example, Kohler has what they call “3-inch” flush valves which really have 3 1/8-inch inside diameter, and use a 4.0-inch flush valve nut. Other manufacturers use "3-inch" flush valves which are different dimensional sizes, and use different flush valve nut sizes (thus requiring a different sized wrench). Aftermarket flush valves (such as Korky or Fluidmaster) complicate matters further.
Here's a good rule of thumb to determine if you have a 2-inch or 3-inch flush valve... If itappears a tennis ball would fit into the circular opening of the flush valve, then you have a 3-inch flush valve.

If you have any doubt whether you’re choosing the the correct tool, please send me a messageBEFORE placing your order. I can send you a pdf document of scaled drawings that you can print to confirm the fit prior to shipment.  Unfortunately, Ebay doesn’t allow me a way to share that file before your purchase, but I have no problem with you cancelling an order if we determine one of these wrenches isn’t going to work for you. In your message, please i nclude your toilet brand, model or model number, and tank model number if it has one. For Kohler toilets, I usually just need the K-(number) inside the tank. If you have a Kohler Cimarron or tank K-4634, I’ll need all the info you can provide including pictures of the toilet and flush valve assembly.

I designed and built these tools myself after my own frustrating attempt to replace a Kohler toilet tank valve seal. My bare hands, a strap wrench, pipe wrench, channel pliers, and other contraptions proved to be worthless. I couldn’t find a suitable tool for the job no matter where I searched. All the help I got from the big box stores amounted to a shoulder shrug, so I gave up on them and designed this tool from scratch. I’ve performed every functionality and durability test I can think of to ensure it meets your expectations. My customers’ satisfaction is paramount. If you find an application where it fails you, tell me about it. I welcome your feedback and I’m committed to improving the products.
Thank you for viewing this item!
