  • The MAG-MIFAB MI-DU Trap Seal Primer Distribution Unit can be installed underneath pressure drop activated trap seal primers to distribute water to up to ten floor drain traps that are near each other.

    Example application: when a men and women’s restroom are located side by side with a common pipe chase between them – so one trap seal primer with a distribution unit dialed to the 2 setting can service both floor drain traps.

MRA-500 Trap Primer
(AG-MIFAB Pressure drop activated trap primer


  • Primes 1-10 traps as little as a 21 kPa pressure drop is needed for our MRA500 primer to function.

    Fact: Other brand needs a pressure drop of 35 kPa before it works.Minimum line pressure of 140 kPa – max 560 kPa.

    Fact: Other brand can only work in a more limited pressure range of 245 kPa to 525 kPa.

    No adjustments required – cartridge tube has a partition moulded in place which determines amount of water discharged from the primer. Other brands have primers that require adjustments to deliver different discharge amounts

    No air pre-charge required – can be disassembled in the field for cleaning and repair and then put back together.

    Other brand has an air pre-charge that once lost, the product cannot be used.Fully serviceableReplaceable sediment filter and servicing

    Inter-changeable cartridge tubesFour view holes (air gaps) for easy inspection of performance

    Distribution Units available, serving up to 10 floor drain taps (Model 80105 – MI-DU)

Product Code: MI-TSP2
Continuous Flow Trap Priming Valve

  • ‘Original’ style of trap seal primers

    The MIFAB TSP-2 Series Continuous flow primer discharges larger amounts of water when water pipes are larger and need a complete flow cycle through the pipes – a “continuous flow” instead of smaller drops of water.

    MAG’s Electronic trap seal primers automatically maintain the water seal of floor drain traps and are available as a pre-assembled, programmed electronic system. Also available is our Hot Water Flushing System which automatically flushes hot water (or cold water) down waste pipes to prevent grease build up.

    Brass body with a neoprene rubber poppet float on the inside that rises upward as water flows through primer

    When the poppet rises off its seat, water flows from the primer, through the plumbing line connection and into the floor drain trap

    Discharges larger amounts of water – needed when water pipes are larger and need a “flow through” or “continuous flow” instead of smaller drops of water

    Increased water flow ensures a complete flow cycle through pipes

    Fully serviceableTwo view holes/air gaps for easy inspection of performance

    MIFAB TSP-2 has threaded connections to be installed in a vertical position within the horizontal water supply line

    WaterMark approved
