How does urinal flush

Includes: - Valve - Battery or Mains options in same kit. This mains powered unit is the size of a mini-downlighter, with a narrow beam, and will only be activated if a user stands under the beam for 5 seconds or more. When the user walks away there is a 3 second delay before the controller flushes for the set number of seconds.

Air Break back-flow preventer : Required to comply with water regulations to prevent contamination of mains water supply. Isolators and Filters: These are standard plumbing fittings but can be added as an option for convenience. It is recommended that an isolation valve is fitted either side of the solenoid valve. If the water flow through the solenoid valve is too fast, spillage from the air break may result.

To remedy this, the isolation valve after the solenoid valve should be adjusted to reduce the flow. Restricting the flow using the isolation valve before the solenoid valve may cause the soelnoid valve to operate incorrectly.

It is also recommended that a Y-filter is fitted before the solenoid valve to prevent debris from constricting the flow through the solenoid valve or urinal spreader. This individual operation urinal control system is designed to flush a single urinal directly from the mains water supply. No cistern is required. The urinal is flushed when the user walks away. The units are extremely versatile in their operation and we have found them to be very reliable indeed.

The design and manufacturing quality are excellent. The installation process is a little more demanding than for some competitive products but that extra time is well spent to ensure the system works as required and continues to do so. Moreover, variable settings allow adjustable time delays between flushing, providing maximum efficiency and savings.

The major disadvantage with this is that the pads have to be replaced and disposed of every week, depending on use. Biological - cartridge containing a microbial stick is fitted into the urinal bowl or trough to break down urine and biofilm.

The principal disadvantage to this system is that the stick dissolves and needs to be replaced 3 to 4 times a year, depending on use. Air flush - Individual traps are replaced by a single trap at the drain end.

A low wattage DC fan provides air flow down the bowl to prevent odour. The waste pipes are specified at 50 mm minimum and installed at fall to prevent scale build up.

Unfortunately, this option is not suitable as a retrofit, but it doesn't use chemicals, the single traps are easy to clean and the fan uses the same power as mains powered urinal controllers.

Cistern Flushing — Another common flushing method involves a cistern flush. The system flushes thanks to an auto-siphon that releases stored water down into the sparge pipes. This will cause the urinal to flush once the water reaches a certain level.

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. The standard toilet flushing system has been around for quite some time, although there have been some significant advancements over the years.
