Question 1

A plumbing permit is required for the replacement of which of the following?

Accepted Answer

Water heater

Answer

Explanation:
A plumbing permit is not needed for the direct replacement of any plumbing fixture, except for a water heater. However, if a fixture location is changed, a permit is required. In other words, you can remove a toilet and replace it with a new one without the need for a permit. But, if you move the closest flange in any way, a permit is required. This is true for all plumbing fixtures.

Question 4

Which of the following types of fixtures can be served by a combination waste and vent system?

Accepted Answer

Sinks

Answer

Explanation:
Combination-waste-and-vent (CWV) systems do not require independent vents on all fixtures. Instead of a vertical vent the fixtures approved for a CWV installation are installed with oversized drains. Due to the larger drain diameter the fixture obtains the needed air for drainage in the top section of the oversized piping. Urinals, toilets, and bidets are not allowed to be installed on CWV systems.

Question 5

Accepted Answer

8

Answer

Explanation:
The plumbing code allows a maximum of eight fixture connections to a horizontal branch drain. This is also called a circuit vent.
