This Gravity Recycler Water Pipe is 13" (33 cm) tall and features a fixed downstem to matrix perc and open cyclone drain. Unlike many other pipes this one has a drain hole that pours out the bottom of the cyclone drain through open air and back into the perc chamber below. The water only drains when the user is not inhaling. Completely designed to prevent unwanted splashback. The pipe includes a matching herb slide and is available in multiple color options.
