Many styles have adjustable shafts, allowing the fill valve to be adjusted up or down to fit different toilet tank depths.Īt this stage in the evolution of toilet fill valves, the device no longer qualifies as a true ballcock, since the floating ball has now been replaced by a different mechanism.

This design accounts for the vast majority of toilet fill valves sold, and it is often the replacement of choice when it comes time to replace an older plunger- or diaphragm-style ballcock unit. This is a very popular and easy to maintain fill-valve style. Water level in the tank is controlled by adjusting where the actuating rod connects to the float cup. The floating cup is attached using a metal spring clipped to a metal actuating rod. This type is identified by a plastic floating O-shaped cup that moves up and down around the fill valve shaft. The float-cup fill valve is made of plastic and is a more “modern” style of anti-siphon fill valve, originally introduced in the late 1950s by Fluidmaster. If you have one of these old-style fill valves they should be replaced, because they do not meet current plumbing codes calling for anti-siphon protection. Cesco Brass also makes a similar style anti-siphon plunger ballcock called the Burlington 20A. Wolverine Brass makes a similarly styled anti-siphon ballcock called the Wolverine Model 50568 (10”) or the Model 50569 (12”) They also make an adjustable height anti-siphon plunger ballcock, Model 56568. The Mansfield 09 is still manufactured by Prier but the ballcock is not listed as anti-siphon by the manufacturer. In 2007, Mansfield’s brass division was purchased by Prier, an excellent-quality brass plumbing and industrial products manufacturer. The de facto standard in early plunger style fill valve was the Mansfield 09, many of which are still in service today. In most cases, these washers were not easily accessible for repairs, so when the ballcock toilet valve no longer closed properly, the whole valve needed to be replaced. The design of the ballcock is very similar to that of older traditional faucets, with a rubber washer.
