ABSTRACT OF THE DISCLOSURE A primer valve for sewer line drain traps which is adapted for use in conjunction with a flushing toilet or like installation including a tank containing water of fluctuating level. The primer valve comprises a pipe penetrating the lower portion of the tank and providing a port at its inner end. Conduit means connect the outer end of the pipe to the trap. Seal means seal the joint between the pipe and tank against leakage of water. A float-operated valve is associated with the port and is actuated preferably by the toilet tank float. The valve is operative to discharge small amounts of water to the trap with changes in level of the water in the tank. The device thus makes use of surplus water contained in the tank without drawing specifically on the pressurized household water supply.
