Plumbing Repairs For Pressure-Valve Toilets

A pressure-flush valve toilet must be connected to a larger-than-usual shaft, 1 or 1.5 inches in diameter, to provide the strong volume of water needed for flushing action directly from a water supply system, rather than from a storage tank. At 30 gallons per minute, it allows water to flow, and this high flow rate can lead to waste or flooding if parts malfunction.

There are three mechanisms in a pressure valve toilet: a built-in stop valve to easily shut water off in an emergency, a handle assembly and the valve itself. On both toilets, the handles and stop valves are virtually similar. However, there are two separate types of pressure valves, one of which uses a diaphragm mechanism and the other a piston. It is easy to distinguish the two forms by their outside profiles.Feel free to find more information at Alpharetta AC Install Association.

A diaphragm valve, which is approximately twice as wide as the pipe leading to it, is identifiable by its one-piece, rounded cover. A piston valve’s cover is slightly wider than the pipe that holds the valve.

Replacing worn pieces prevents leaks or other malfunctions. Since parts produced by various suppliers are not compatible, be sure to remember the name of the manufacturer; the device is clearly stamped, usually on top of the pressure valve.

By changing the stop valve, the flow rate of a diaphragm-type valve is controlled. The diaphragm controls the length of the flush cycle automatically. On a piston-type valve, by turning a screw on top of the valve, both the flow rate and the flush cycle are controlled.
