Fully functional flush valve kit

Would Recommend

Used this kit to replace a leaky flange. Kit included detailed instructions. Be sure to have a large enough wrench on hand to remove the plastic nut from your previous valve.

Flush Valve

Would Recommend

Fit and worked perfectly after making flush adjustment. The flush adjustment requirement was well described on the installation instructions. Of course I didn’t read them before installing.

A Brilliant Water Cost Reduction

Would Recommend

Our historical home had a continuous water cost beyond normal. This was the perfect fix. Our bluetooth Flume water use monitor now shows absolutely no continuous water usage.

Flushmaster 3 in

Would Not Recommend

I had to return the first one, it leaked worse than the one I replaced. The second one leaked also but I took steel wool and a fine abraser to make the float set. It was dishearting to have to tear down the back of the water closet 2 times with new material.

Crappy seal

Would Not Recommend

The rubber gasket that seals the valve to the toilet is garbage. It is ridged and leaks water through to the drain underneath. The gasket needs to be a flexible squeezable joint to stop water from getting by. Do not by this!

Leaked

Would Not Recommend

Bought this to replace a leaky flush valve and it leaked even worse than the old worn out one. Not sure if I just had bad luck and got one that wasn't seated correctly, but I was not thrilled to have to tear my toilet apart a second time to replace the replacement.
