Checking Your Water Pressure and Pumping Rate

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage,

Minimum water pressure required at the filter tank inlet is 20 psi. If pressure is over 100 psi, a pressure reducing

valve must be installed in the water supply line ahead of the Mazzei injector. NOTE: If you have a municipal or

community water supply and daytime water pressure is 85 psi or more, nighttime pressure may exceed 100 psi. Call

your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on

the pressure tank will indicate the high and low system pressure. Record your water pressure data below:

Low __________________ psi

High __________________ psi

The pumping rate of your well pump must be at least 5 gallons per minute (gpm) for satisfactory operation of the

Mazzei injector. In addition, the pumping rate must equal the backwash flow rate of your filter. To measure the

pumping rate of your pump, follow these instructions:

Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and

measure time (in seconds) to refill pressure tank (when pump shuts off). This figure represents cycle time.

With the pressure tank full, draw water into a container of known volume and measure the number of gallons

drawn until the pump starts again. This is draw down.

Divide the draw down figure by the cycle time and multiply the result by 60 to arrive at the pumping rate in

gallons per minute (gpm).

DRAW DOWN ÷ CYCLE TIME x 60 = PUMPING RATE

Locate Water Conditioning Equipment Correctly

Select the location of your filter tank with care. Various conditions which contribute to proper location are as follows:

Locate as close as possible to the water supply source.

Locate as close as possible to a floor or laundry tub drain.

Locate in correct relationship to other water conditioning equipment (see Typical Installations, Page 4).

Filter and softeners should be located in the supply line before the water heater. Temperatures above 110° F (43°C)

will damage the equipment and void the warranty.

Do not install a filter or softener in a location where freezing temperatures occur. Freezing may cause permanent

damage to the equipment and void the warranty.

Allow sufficient space around the unit for easy servicing.

If your water source is a community or public water supply or if you wish to bypass water used for a geothermal heat

pump, lawn sprinklers, out buildings or other high demand applications, refer to installation instructions.

The Importance of Your Pressure Tank

The pressure tank found on private well systems becomes an integral part of the filter system by providing necessary

mixing and "contact time" to the "air-injected" water. While the iron filter will perform better on a standard air-to-water

pressure tank, it will perform satisfactorily on a captive air (bladder) pressure tank. The bladder tank requires more

careful adjustment of the Mazzei injector and careful location of the air relief valve.

If cycle time on the pumping system is less than 30 seconds and under severe operating conditions (low pH, high iron,

manganese and small concentrations of hydrogen sulfide), a standard air-to-water pressure tank with an air relief valve

must be used (if a bladder tank is already in place, do not remove it, install the air-to-water pressure tank between the

Mazzei injector and the bladder tank).

NOTE: If your pressure tank (or any part of your water system) is not functioning properly, corrective action must be

taken before installation of your chemical free iron filter.
