## Overview

The Champion 4 Flush Valve Tune-up Kit is designed to enhance your toilet's performance by providing essential replacement parts, including two silicone seals and silicone glue. This kit not only increases the water capacity in your toilet tank but also effectively stops leaks and prevents ghost flushing, ensuring a reliable and efficient toilet experience.

## Description

This Package includes 2 replacement seals for the Champion 4 flush valve and a tube of Silicone Glue. There are 6 different lengths of overflow tube extensions that will increase your water in your toilet tank from 1 inch to 6 inches. Choose the length that works best for the height of your toilet tank. They are easy to press into the overflow tube and change from one to a taller or shorter size for the best flush. You can cut longer tubes for the best height to use on several toilet overflow tubes. These tubes fit inside the overflow tube in your Champion 4 toilet to increase the water level in the toilet tank. The Champion 4 overflow tube is tapered and the more you tighten the tube the better the seal. You can get a seal in some cases that you will not need glue. Your Champion 4 toilet will flush better with more water. The increased weight of water in the toilet tank will hold the flapper valve down better so the flapper will seat and not leak. Otherwise, the flapper valve has a tendency to float and not seat due to only having the weight of 4 inches of water above the flapper and below. We have also sent two red rubber seals that are heavier than silicone and will not float as easy. The Champion 4 flush valve leaves 4 inches of water on the bottom of the tank and never leaves the toilet tank.

## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Stand up company.
  

*by K***N on Reviewed in the United States on March 26, 2018*

Let me start by saying, the company, NuFlush, was great.  If this review was just about the company, then I would be giving them 5 stars, I'd go 4.5 if that was possible.  The reason for the less than 5 stars is the product solution itself fell short of fixing my problem.  The problem is that American Standards design is seriously flawed, and they know it, which is why if you contact them, they will send you a new gasket for the flush valve for free.  But even that doesn't fix the flaw, or stop the leak.  It is just a horrible design that fails on many levels.  First off, the valve itself sits 4 - 5 inches off the bottom of the tank, which means there is a lot of water that is never in play, not used for actual flushing and more importantly, less weight pushing down on the gasket.The orange tubes can add a little bit more water to your tank, but in the American Standard 4215A toilet, you can't really add very much more water, maybe an inch at most, more likely just a half inch.  Which wasn't enough to add enough pressure onto the gasket to get it to stop leaking.  When the orange insert was in, and the water level was a little higher, the toilet seemed to visibly flush with more water.I did not try using the gaskets that NuFlush shipped with the kit, I had already received an American Standard replacement gasket and that didn't help any so I didn't think trying the gaskets from NuFlush would be any different.So here is where NuFlush the company itself truly shines IMO.  They called me up and offered to send me a new flush valve in addition to the kit.The new flush valve solved the problem, and unlike the replacement flush valves at the big box stores, or an OEM replacement, this new valve corrects all of the short comings of the American Standard design.  It puts the valve opening at the bottom of the tank where it belongs, and because of the height of the overflow tube, I'm guessing it took my 1.2 gallon American Standard all the way up to close to 2 gallons per flush.Frankly, I think the tubes can help make your toilet flush better by adding some water to it, but the tubes probably aren't going to do much towards stopping the leak through the flush valve.
