Tank and Control Valve Connections
5. Connect the drain hose to the valve and secure it with a hose clamp. Run the drain hose to
the nearest laundry tub, floor drain or approved air gap fitting. The drain can be ran overhead
or down along the floor. Drain tubing should be a minimum of
1/2”
ID. When running the
drain overhead it is important that the tubing has no dips or kinks. If the drain is ran overhead
and must run linearly to the available drain it is recommended that a hard pipe is used of larger
diameter than the drain line. This linear pipe should have a physical
“
drop
”
toward the drain
(1/2”:10’).
The goal is to have a gravity drain without much back pressure when traveling long
distances.
NOTE:
A DIRECT CONNECTION INTO A WASTE DRAIN IS NOT RECOMMENDED. A
PHYSICAL AIR GAP OF AT LEAST
1.5”
SHOULD BE USED TO AVOID BACTERIA
AND WASTEWATER TRAVELLING BACK THROUGH THE DRAIN LINE INTO THE
SYSTEM
.
NOTE:
Be sure to secure the drain line. The system will drain with force and it should
be secured to prevent a leak. Hose clamps should be used to secure the drain
line at the connection points.
