Function: Used in the outlet connections of floor drain bodies, or the inside of floor drain strainers to seal the opening to prevent odors, sewer gases, and insects from entering up through the floor drain grate. The MI-GARD®'s four flexible silicone sealing ribs ensure easy installation into openings that have variations in size. The MI-GARD® will open to allow drainage and close when there is no water flow.

Function: Used in restaurants, kitchens, bars, institutions and other types of food processing areas where fat, oil and grease (FOG) and food particles drain with the waste water. Installed directly under or close to the drain sink, grease and food particles are trapped prior to entering the municipality mandated grease interceptor. A disposable filter is required for operation. Two types of filters are available - a fine mesh filter specifically designed for coffee grounds and a general use solids filter.

Specification: MIFAB-s MINI-PL is a one piece high Density Polyethylene (HDPE) wet waster interceptor with two removable polycarbonate plastic strainer trays, removable filter, 2" HDPE no hub inlet and 2" HDPE no hub outlet connections and four adjustable support legs.

Backflow preventers are used within direct connect piping systems to allow water to enter a building from the local water supply but do not allow water from inside of the building to flow back into the local water supply due to back siphonage or pressue loss.

Function: The assembly shall consist of two repairable positive seating check modules with captured springs and rubber seat discs. Service of all internal components shall be through a single easily removable cover and designed for ease of access.

Features: Single access cover for fast service, screwed on access cover for quick repairs, easily removable checks, modular design reducing number of spare parts, and self-contained check so there is no pressure on the lid.

Ratings: Maximum working water pressure 175 PSI, Maximum working temperature 180° F, Hydrostatic test pressure 350 PSI, End connection NPT threaded to ANSIB 1.20.1

Pressure drop activated trap seal primers are connected to the cold water supply line.   There is an internal cartridge that is activated when the line pressure changes by as little as 3 p.s.i. and discharges water from the bottom of the trap primer into a line that is connected to the p-trap or floor drain to maintain the water seal in the p-trap.  Otherwises, dry p-traps can lead to foul odors entering a building.

MIFAB® MR-500, M1-500 & M2-500 Series pressure drop activated brass trap seal primer, with inlet opening of 1/2" male N.P.T. and outlet opening of female 1/2" N.PT. Complete with four view holes and removable filter screen. Requires no adjustments and no air pre-charge. MIFAB's Series of pressure activated trap seal primers (MR-500, M1-500 and M2-500) can be connected to any cold water line and will be automatically activated when a valve or faucet, that is on the line, is opened.

A pressure drop of three p.s.i. will activate all of the trap seal primers. MIFAB's Series of trap seal primers can be disassembled in the field. Their unique design permits filter replacement without affecting the performance of the primer. The "O" ring seals are tested for reliability at a temperature range of -40 degrees to 450 degrees F. The M-500 Series of trap seal primers do not require adjustment. The operating range for all of MIFAB's Series of trap seal primers is 20 to 80 p.s.i.²

All three models are listed with I.A.P.M.O. and C.S.A. and are tested and certified to the A.S.S.E. Standard 1018 and are so marked. U.S. Patent # 6,152,164.
