Types Of Toilet Fill Valves

The five most common fill valves you may find in your home include.

Types of toilet fill valves.

Fill valves are generally activated by either a float ball or float cup device. There are only two basic types of valve mechanisms for each of these operations. Plunger or piston style fill valves are perhaps the very first types ever. There are at least five different types of toilet fill valves with different mechanisms to control the water flow inside the tank.

The easiest way to buy a suitable replacement is to bring the old fill valve with you to the store where the clerk should be able to direct you to several acceptable replacements. The cylinder rises and falls with the water level in the tank. The floats are empty ball shaped structures serving to open or close the fill valve according to the water level inside the tank. For toilet fill valves the anti siphon device is a vacuum breaker or an air gap and it is located on the side of the valve where water flows through the refill hose and into the overflow pipe.

This style of ballcock uses a base fill water release tube and comes with a pivoted switch system over the ballcock. It all depends on the size and type of toilet you have. Ballcocks or plungers are one of the older styles of fill valves and they consist of a brass body bottom fill discharge tube a hinged lever assembly and a floating ball. Toilet valves used for flushing are typically either a flapper or siphon style mechanism.

The fill valve sometimes referred to as a ballcock is the assembly that sometimes has a floating cup or cylinder along its shaft. They are made of a hardcore cast metal body. The attached floating ball opens and closes the plunger s stem depending on the water level. Some toilet tanks may have flush valves with oversized overflow tubes that require a specialized fill valve.

Diaphragm type fill valve brass body. What is the best toilet fill valve. Thumbscrews at some pivot joints allow changing of the switch arm movement. The fill valve and the flush valve.

The inner workings of the basic toilet tank contain two types of valves. Float cup fill valves use the same overall principles to keep a toilet functional that float ball fill valves do. Fill valves or ballcocks are devices that regulate water flow in your toilet. Some fill valves are adjustable to fit different tank sizes.

Toilet valves used for flushing are typically either a flapper or siphon style mechanism. In contrast with float cup type toilet fill valves float cup type fill valves are more modern. However floatless fill valves are the most efficient because they help reduce water consumption in each flush.
