M A Griffith offers two methods of trap priming systems.

MAG-Mifab MR-500 Pressure Drop Trap Primer
This is a mechanical valve which is a automatic - pressure drop trap primer valve - these are designed to maintain a water-seal in a floor waste, commonly used in commercial buildings thus preventing foul smelling air from entering a building.

The valve is connected to a water supply whereby fixtures are upstream and downstream of the priming valve, when a fixture is operated, this creates a pressure drop in that line causing the MAG-Mifab primer valve to deliver a uniform amount of water that feeds the trap maintaining that water seal.

We also provide a distribution unit which allows more than one trap to be primed at the same time.

MAG 38003 Electronic Trap Primer
The electronic trap priming system uses a solenoid valve and timer controller to automatically charge the trap at a preselected on the timer.

These are normally used in a plant room or at the end of a line where there are no fixtures, hence no pressure drop.
A 15mm cold water line is directly connected to the valve.

A distribution unit is provided if more than one trap is required to be charged.

We also provide a 'hot water flushing system' which has as selection of times and is designed operate a solenoid valve and flush hot water down a greasy waste line - currently used by Coles, Safeway and Woolworths under chicken cookers to prevent a build up of grease in the waste line leading to the grease trap.
