• Use piping or ducting at least two (2) diameter sizes larger than the vacuum connection.
Overall vent pipe length—horizontal plus vertical—should not exceed 100 feet (about 30
m) and should not include more than three (3) elbows. If you use pipe for venting, make
sure that you use Sch. 5 or Sch. 10 pipe with long radius elbows to provide minimum
airflow resistance. If you use ducting, make sure you use high-pressure ducting with
mitered bends—with a minimum of three (3) breaks—for minimum airflow resistance.
Make sure all piping connections are properly supported.
• If you are venting pump discharge outdoors, make sure you properly terminate vent
piping to prevent pump damage. You can either:
a. Install a rain cap, or
b. Install the piping so the exhaust faces down and terminates with a screened
opening.
If the pump becomes contaminated from rain or airborne particulates, or is
damaged by birds, insects, or small animals, your warranty becomes void!
Any variance from these guidelines can cause excessive pump backpressure. Such
a condition can drastically affect equipment performance, possibly leading to
equipment damage.
