Johnson Screens are commonly used in shallow wells, Johnson Screen’s proprietary, sonic-welded PVC VeeWire® screens present higher open area for given slot size than any other non-metallic screen available. More economical than metal screens, PVC Vee-Wire screens resist corrosion from salts and gases commonly found in either salt or freshwater, and they may be treated repeatedly with hydrochloric acid or Johnson's Nu-Well® pellets to remove incrustations.
