ABSTRACT:
An inline filter comprises transparent upstream and downstream halves defining truncated hollow right-circular cones whose flanged lower bases sandwich therebetween a concentric brass filter screen fixedly carried by the flanged lower bases joined together by heat-sealing. The upstream and downstream halves have respective male fittings for connection to respective upstream and downstream female couplings on an incoming water supply line for flow of such incoming water through the inline filter. The filter screen, which has an effective filtering capacity, area-wise, of almost 13 times the area of the internal diameter of the upstream male fitting, filters out and traps sand, dirt, particles and other debris carried by the incoming water. The transparent halves provide visual indication whether the filter screen is clogging up. Connecting the upstream female coupling to the downstream male fitting effects backflushing water flow to clean the filter screen.
