Frequently Asked Questions (FAQs)

1. How does a urinal flush valve work?

Hydraulic Valve Flushing – A hydraulic valve flushing system is installed in line with the water supply inlet pipe into the cistern. The valve works by sensing a temporary drop in pressure in the water supply. When this pressure drop occurs, the valve will release water into the cistern.

2. What are the two types of flush valves?

Toilet flush valves come in the following formats: standard, 3-inch, 4-inch, tower-style (also called canister-style), and dual flush valves.

3. How do you adjust a urinal flush?

Loosen the top of the valve system by rotating the retaining bolt with an adjustable wrench. This will give you access to the flush valve. Use your adjustable wrench to rotate the flush valve. Spin it clockwise to decrease flow, and counterclockwise to increase flow.
