Corky fill valve pulses when filling toto toilet, How to fix?

SOURCE: Toto toilet Power Gravity intermittently running

You need to either bend the arm that connects tot he float down (if it is the type with the ball float) or adjust the height of the fill valve assembly. THis accomplished by slightly twisting the valve assembly carefully and sliding down a half of an inch or so and then twisting back to lock it in place.

This should fix you up right.

Shorten the chain link so that when handle is pushed down the flapper stands more upright. Dont shorten to much so that it wont seat all the way either. Good Luck and a Great Day. Please rate 4 THUMBS UP if this was helpful.

You need Korky Part # R528 available at Home Depot. Instructions are on the package and it takes just a few minutes to change it.

SOURCE: toilet fills up and water

If any toilet runs (continues to fill) when it is not being used, there are basically 3 reasons. the most obvious is that water is leaking out all over the floor so the fill valve thinks the tank has not reached its volume of water. Next, the rubber device that keeps the water in the tank when not being used (most commonly called a flapper) has warped from time or chemicals in the water (NOTE:chlorine eats rubber for breakfast daily), and and allows water to seep past it, which lowers the water level and triggers the fill valve to come back on to top things off.
The third reason is because there is particulat in the fill valve or mineral buildup and internally it doesnt always properly seal so it can run intermittently or all the time.
All the parts on the TOTO ultramax are warranteed for 5 years so keep that in mind if it applies.
Remove the tank lid when you hear the fill vave working and look at the water level. If the water level is below the top of the white plastic tube that the flapper is connected to (often called the overflow tube), then you have a bad flapper. If the water level is going over the top of the tube then you have a defective fill valve.
Out of warranty fill valves can easily be replaced with a Lavelle "Quiet fill" available at most hardware or plumbing stores or online.
This valve is what Toto uses in most of their toilets and it is only the removeable cap that is different (subliminal advertising maybe)
