Instructions / Assembly

Special Attention for situations where a Filter and a Softener are installed
together:
When a whole house filter and a softener are installed side by side, the only option is to run a separate
drain line from each unit all the way to the point of termination. If this is not done, there is the potential
for drain water from the filter to back feed through the softener and overfill the brine tank, especially
when drain lines are run overhead. (Please note that back feed goes only into the brine tank, not the
service line.)
If circumstances require you to tie the drain lines together, please use the following method to avoid
back feed issues:
Run the drain lines from both systems to the point of termination, and tee them together before the air
gap. (See figures below)
