Jay R. Smith 2698 Water Saver Trap Primer - Satin Chrome

 

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 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. Thus, the floor drain trap seal is maintained.
