,
the ferrous impurities
are captured by a strong
neodymium rare-

magnetic field created by a powerful
removable magnet around the body below
the flow line.

Troubleshooting
System failures are not always caused by the
pressure reducing valve. Most frequently:
1. Increased downstream pressure in the
presence of a water heater
If the downstream pressure increases
beyond the desired setting due to an
inline water heater, install an expansion
tank between the pressure reducing
valve and the water heater to absorb
the increased pressure, caused by
water expansion from heating.
2.The pressure reducing valve does not
maintain downstream setting value
If the pressure reducing valve does
not maintain the downstream setting, it most likely is due to impurities acccumulating
on the valve seat, causing unnecessary flow to pass-through, increasing the downstream
pressure. Proper maintenance and cleaning of the removable cartridge is recommended.
