Massachusetts Plumbers Journeyman Practice Exam

What are the two acceptable tests for Drain and Waste?

1. Water Test and Oil Test

2. Peppermint Test and Smoke Test

3. Peppermint Test and Air Test

4. Visual Test and Sound Test

The correct answer is: Peppermint Test and Air Test

The correct answer identifies the Peppermint Test and Air Test as the two acceptable methods for testing drain and waste systems. The Peppermint Test involves the introduction of a peppermint solution into the drainage system to identify leaks. The peppermint scent is easily detectable and allows for quick identification of any points where the system is compromised. The Air Test, on the other hand, involves pressurizing the system with air and checking for any drop in pressure, indicating potential leaks. This method is effective in ensuring that the waste lines are sealed properly and can handle the pressures of operation. Together, these methods provide reliable ways to assess the integrity of drain and waste systems, making them the preferred choices for professionals in the plumbing field.
