Which of the following types of foundations would create the greatest problem for the plumber when relocating a toilet during a remodeling projects?
- A.
Shallow foundations (grade beam)
- B.
Crawl space foundations
- C.
Basement foundations
- D.

Your client is worried about the toilet location near the kitchen. She is concerned that her guests may find the noises associated with a powder room will be unpleasant. You have discussed sound dampening methods with her and the concept of Sound Transmission Classification (STC). To achieve the highest STC rating you have suggested the use of drywall with the following wall construction...
- A.
Double 2x3 stud walls with 3" (76mm) insulation between staggered studs.
- B.
2 x 6 walls.
- C.
2 x 4 walls with wallpaper on the interior walls rather than tile.
- D.
2 x 4 walls with 1-1/2" (38mm) fiberglass acoustic insulation, resilient channels.
Correct Answer
A. Double 2x3 stud walls with 3" (76mm) insulation between staggered studs.Explanation
The correct answer is double 2x3 stud walls with 3" (76mm) insulation between staggered studs. This construction method provides better soundproofing by creating a double layer of walls with insulation in between. The staggered studs further reduce sound transmission by preventing sound waves from easily traveling through the studs. This combination of double walls and insulation helps to minimize the noise transfer from the powder room to the kitchen, making it the best option for achieving a high Sound Transmission Classification (STC) rating.Rate this question:

Kitchen and Bath designers should always make sure their projects are being installed under a valid building permit. Depending on the municipality, more than one permit may be required. Your project includes some wall alterations for a new master bath suite. In a typical remodeling project, when would the first inspection be conducted?
- A.
After the plumbing fixtures are set.
- B.
After the electrical and plumbing rough in.
- C.
Before any work starts to determine the scope of the project.
- D.
After the rough framing is completed.
Correct Answer
D. After the rough framing is completed.Explanation
The first inspection in a typical remodeling project would be conducted after the rough framing is completed. This is because the rough framing is the initial stage of construction where the basic structure of the project is built. Inspecting the framing ensures that it meets the required building codes and regulations before proceeding with further work. It is important to have this inspection early on to identify any potential issues or necessary corrections before moving forward with the project.Rate this question:

You have determined that the hood of your next project will require a rating of at least 800 cubic feet per minute. (22.7 cubic meters per minute). To prevent "backdrafting" you suggest which one of the following?
- A.
Increase the cfm capacity to at least 10% of the recommended size.
- B.
Decrease the cfm capacity to at least 10% of the recommended size.
- C.
Tell the client to open a window when using the hood.
- D.
Provide a dedicated source for "make-up" air.
Correct Answer
D. Provide a dedicated source for "make-up" air.Explanation
To prevent backdrafting, it is necessary to provide a dedicated source for "make-up" air. This means that in addition to the exhaust air being removed by the hood, fresh air needs to be supplied to the space to maintain proper air circulation. This helps to balance the air pressure and prevent negative pressure, which can lead to backdrafting. Increasing or decreasing the CFM capacity or simply opening a window would not effectively address the issue of backdrafting.Rate this question:

During your inspection of the home you stop at the kitchen sink to check for adequate water pressure. What is the suggested range (min/max) for the incoming water pressure?
- A.
25-75 psi
- B.
30-80 psi
- C.
30-50 psi
- D.
50-80 psi
Correct Answer
B. 30-80 psiExplanation
The suggested range for the incoming water pressure is 30-80 psi. This range ensures that the water pressure is neither too low nor too high. Water pressure below 30 psi may result in weak flow and difficulty in performing tasks, while pressure above 80 psi can cause damage to plumbing fixtures and appliances. Therefore, the range of 30-80 psi is considered adequate for the kitchen sink.Rate this question:
