1. Shut off all water at main supply. On a private well system, turn off power to
pump and drain pressure tank. Make certain pressure is relieved from complete
system by opening nearest faucet to drain the system. Shut off fuel supply to
water heater.
2. Cut main supply line as required to fit Mazzei injector in plumbing between well
pump and pressure tank (Mazzei injector may installed in a vertical or horizontal
position). Be certain direction of flow arrow on the Mazzei injector points toward
pressure tank and pressure control switch is located on the pressure tank side of
the Mazzei injector (rapid cycling of the pump may occur if pressure switch is
located on the well side). If check valves are used, they should be installed
before the Mazzei injector, not between the Mazzei injector and the pressure
tank.
NOTE: It is advisable to install the Mazzei injector with the unions at both ends to
facilitate removal and inspection. On badly scaled older pumping systems, it may
be advantageous to install an optional "y" strainer ahead of the Mazzei injector to
prevent plugging the injector nozzle with scale.
3. Cut the main supply line as required to fit plumbing to the control valve with bypass.
4. Solder or solvent weld plumbing. Do not apply heat to any fitting connected to the control valve as damage may
result to the internal parts. Check to be certain water supply pipe is connected to the control valve inlet fitting and
pipe connected to control valve outlet fitting is in direction of house service.
NOTE: If the installation is to be split-streamed prior to the filter tank or is a public water supply installation, refer to
special instructions.
