Question 1

It is necessary for sewage pumps or sumps used to store sewage to be ________.

Accepted Answer

Both "vented" and "covered with a gas-tight cover"

Answer

It is necessary to vent sump sewage pumps that remove sanitary waste to the outside air. If a pneumatic sewer ejector pump is to be installed, the vent cannot be connected to a general venting system. The vent can be connected back to a common venting system when a standard sewer pump is to be used. A vent for a sewage sump will typically need to have a minimum diameter of two inches. Sewage sump coverings, in addition to effective venting, must be gas-tight.

Question 2

When is a cleanout appropriate for a new fixture installation? What, in other words, qualifies the removal of a cleanout plug, its replacement with a male adapter, and the subsequent extension of piping to a new fixture?

Accepted Answer

When approved by a code enforcement officer and another cleanout is provided to replace the one being used as a connection point of drainage piping for a new fixture.

Answer

Unless the connection is authorized by a code officer and a new cleanout is provided to replace the cleanout being converted to a connection point for drainage piping, fittings housing cleanout plugs are not permitted to be utilized as a connection point for a drainage pipe that will feed a new fixture.

Damage during or related to backfilling of the water service trench
