Kohler1068031 Fill Valve

We used this piece to repair the toilet. Perfect and pretty easy to install.

This valve was a perfect replacement for the Kohler Rialto. The difference seems to be this one has the rinse water bypass so it needs the vinyl hose to provide water to rinse the bowel while it fills the tank. The original valve did not have the hose or the clip. The hose is NOT included with this valve. I got one from Home Depot. We have had it for a couple of months and it works perfectly. This took 15 seconds to replace because there is a quick release coupling between the riser pipe and the valve assembly. A quarter twist and the valve portion separates from the riser/fill pipe. Super easy to replace.

This was so easy to install. My husband had it done in less than 10 minutes! We liked it so much and it's whisper quiet, we're getting another one for the toilet in the basement! Affordable!

Replaced the old assembly perfectly! Used to replace the fill valve on the Kohler Rialto (made in China)

Some reviews mentioned that the kit didn’t come with a specific part (a nut?), but this wasn’t my experience. It came with clear enough directions, and I installed this toilet flushing mechanism in minutes without any problems. It is a good value because I used to pay more than $16 over the Amazon price in my local hardware store. I adjusted it so that my toilet tank fills up to the exact level that I want.
