Flush Valves for Water Closets and Urinals

In the most effective and up to date plumbing installations the use of a tank with its complicated mechanism is discarded and in its place a flush valve is installed. In nearly all public buildings, such as hotels, office buildings, schools, court houses, factory buildings, etc., the flush valve is now almost entirely used, as the old style tank is easily gotten out of order, whereas a flush valve is simple and fool-proof. I advocate very strongly the use of these valves in all public buildings.

The water supply to a flush valve must have a rate of flow sufficient to properly flush the closet bowl. The pressure at the flush valve and the length of the supply line determine the size of pipe required. The size indicated in the table is suitable for one closet or three urinals. The pressure should never be less than 5 lbs. at the flush valve.

Made sufficient by compression tank, Figure No. 2 shows a typical installation of flush valves with gravity tank. Figure No. 3 shows a typical installation with small supply from street main made sufficient by basement compression tank.

There are several makes of flush valves on the market. One of the oldest and best is the Royal Flush Valve
