ABSTRACT A Walker-type, toilet tank-activated, drain trap primer assembly has a flexible conduit interconnecting the after- fill pipe and the trap priming pipe. Valve means on the flexible conduit restrict the flow therein to a predeter- mined minimum. Check valve means in the conduit prevent backflow of the trap contents in the event of loss of pressure in the pressurized house line supplying the toilet.
