"PRIME-EZE" WATER SAVER TRAP PRIMER
FUNCTION: The water saver trap primer utilizes the temporary "head" of water in the p-trap which occurs during use of certain plumbing fixtures like lavatories and drinking fountains. This temporary head of water is sufficient to cause an "overflow" through the primer tube connection to allow a small amount of water to flow by gravity through a pipe under the floor to the floor drain trap primer connection to maintain the floor drain trap seal.
