Can a tank be cleaned through a clean-out?
No. A clean-out is used to unstop a line from outside of the house and is generally placed within a couple of feet from the house. A tank can be cleaned through a 4: x 6: pipe installed over the tank lid which is called a riser. However, we do not recommend this method of clean-out. In case of an emergency, a riser dos not allow for easy access to the tank lid. With a riser you can not tell if all the waste material was removed, and with pump back systems it is very important that ll of the solid waste be removed. Manholes are a more practical and more cost efficient solution.
