Cleaning the Nozzle and Venturi

A clean nozzle and venturi (see Figure 12) is a must for the conditioner to work properly. This small

water softener creates the suction to move brine from the brine tank, into the resin tank. If it should

become plugged with sand, silt, dirt, etc., the conditioner will not work, and you will get hard water.

To get to the nozzle and venturi, remove the top cover. Put the bypass valve(s) into bypass position.

Be sure the water softener is in soft water cycle (no water pressure at nozzle andventuri). Then, holding

the nozzle and venturi housing with one hand, turn off the cap. Do not lose the o-ring seal. Lift out the

screen support and screen. Then, remove the nozzle and venturi. Wash the parts in warm, soapy water

and rinse in fresh water. If needed, use a small brush to remove iron or dirt. Do not scratch, misshape,

etc., surfaces of the nozzle and venturi. Also, check and clean the gasket and flow plug(s).

Replace all parts in the correct order. Lubricate the ()-ring seal with silicone grease and locate in

position. Install and tighten the cap, by hand only. Do not overtighten and break the cap or housing.

Put the bypass valve(s) into service/soft water position.
