Frequently Asked Questions

Q. "When I flush my toilet the fill valve does not start refilling until most of the water has drained from the tank. Why does this happen?"
A. With a Korky toilet valve, standard on Toto toilets, you'll eventually have a situation where you flush the toilet, and it takes a few seconds, sometimes ten or more, before the valve will begin refilling the tank. The most common cause is the chamber that contains the float has become clogged from residue and open completely, giving a slow response in refilling the tank. This chamber has a small ball valve at its bottom, and this must empty the float chamber in order for the float to drop and open the fill valve.
To clean the ball, turn off the water to the toilet and flush the tank. Then remove the float chamber cover and then the float by gently squeezing its arms at the top of the fill valve. Using a semi-stiff paint brush and a few glasses of water, clean the ball and seat at the bottom of the float chamber. Replace the float and cover, turn the water on and you're ready to go.

Q. "I installed a new fill valve and my new valve comes on (and then goes off) for a few seconds about once per hour?"
A. This could be caused by many things. The most common is with a Fluidmaster 400. This is a great valve but be sure to install the 1/4" tube per their instructions. Use the clip that comes with it and do not just stick it into the overflow tube or it will go on and off every so often by itself. If that isn't it, take some food coloring and place it in your tank. Wait a few hours and if some of the color has gone into the bowl then you probably need a new flapper.

Q. "What are the most commonly replaced toilet parts?"
A. This depends on several factors; each time you use your toilet the trip lever, flapper, and fill valve are operated. You will find, however, that the flapper and fill valve are the parts most exposed to water and will be the first ones to wear out in most cases.

Q. "What does 'will fit' mean?"
A. "Will Fit" is a term used to define an item that may or may not be made by the original manufacturer (OEM), but will function just like the original part.
