ABSTRACT:
An anti-syphon device for a water supply line of a toilet tank having an opening in a bottom wall thereof. A tubular inlet fitting is mounted in the opening and has a lower portion extending downwardly from the bottom wall. The water supply line underlies the inlet fitting and includes a main portion, a head portion of enlarged diameter, and an outwardly extending flange at an upper end of the head portion. A washer forms a seal between the flange of the water supply line and the lower portion of the inlet fitting. The washer includes a portion extending inwardly of the head portion. There is a valve seat at the lower end of the head portion and a valve member, which is inside the head portion, engages the valve seat to form a seal therewith. A compression spring bears on the valve member and on the inwardly extending portion of the washer member to urge the valve member to closed position.
