There are three old Kohler toilets in my house dating from about 1953, in addition to one new model in the master bath we added on. The old toilets recently all needed to have the flush valves replaced. These are the old style ball on a rod type, and are still available cheap. While I was doing that, I decided to update the fill valves, too, since they were getting pretty old, though I doubt they were the originals. Anyway, at both Lowes and Home Depot, and the local Ace Hardware, the Flushmaster was what was recommended. It's cheap and easy to install, and is easily repaired or replaced when that is required, so I went for that. However, after installing them, I saw that they send much more water down the overflow tube, where it first fills the bowl and then goes down the drain. I assume these valves are intended primarily for use with the low-flush volume of the newer toilets, and since my old style toilkets take quite a bit longer to fill the tank, a lot of water is wasted down the drain by this feature.
The good news: I e-mailed the Flushmaster folks to ask them about that since there was no obvious way to adjust the flow to the overflow tube. They immediately replied with an offer to send me three free adapters to adjust the flow. How about that?
I assume some of their competitors make valves with either a lower flow or an adjustable flow to the overflow tube, but I like a company that responds to my questions.
