Project Planning & Design 3 Flashcards
How should the performance of materials be considered during the design phase?
Materials should be tested to assure they will perform as expected and designed.
The life span of the material should be evaluated to make sure it will withstand normal wear and tear.
If a building extends underground below the level of the ______ there is a need for an active drainage system, including a sump pump.
Water table.
What are two things that should be done in a plumbing system design to prevent contamination of the water supply.
Provide for secondary drain access at all fixtures to prevent any used or supplied water coming into contact with a supply spigot.
Faucets need to be above the level where a basin (such as a kitchen sink) would overflow.
ADA showers must be equipped with:
A fold-down seat, a showerhead attached to a flexible supply hose, grab bars, and the absence of a front curb or step-in that would prevent access via a wheelchair.
What is a valve that operates by placing a barrier or gate in the path of water flow called, and name an advantage.
Gate valve.
One advantage of the gate valve is that when the valve is open there is nothing restricting the water flow.
What is a valve that pushes water from one chamber into the next, thus, losing some water pressure.
Globe valve.
An electronically controlled valve that can go from open to closed rapidly is called a:
Solenoid valve.
Every vent needs to connect to the stack vent or otherwise be part of a _______ that exhausts at least a foot above the roof surface.
vent stack
Waste (sewage) is conveyed from the building’s waste system to a public sewer system through a portion of pipe referred to as the building:
Sewer.
In systems where waste water may be collected below the level of the sewer - such as a house with a washing machine in a basement - waste water would need to be pumped back up high enough so that it could be fed by gravity into the building sewer. Typically this requires some sort of a catchment area and pump mechanism. The pump is know as a:
Sump pump.
In cases where there is a commercial kitchen (such as a restaurant) a place to collect grease is required. This is called a:
Grease trap.
The main vent for a building is called the:
Stack vent.
What does DWV stand for?
Drain, waste, and vent.
What is a trap and where is it in a plumbing system?
Each fixture is required to have a trap. From there, the waste connects to a sloped drain pipe and that in turn is connected to a vent.
Depending on the building code, there may be a requirement for an additional trap that would trap gases from the sewer traveling to the building.
What are drains?
These pipes eventually lead to the lowest level of drain pipe, which is called the building drain.
Water suitable for drinking is called:
Potable water.
A fire sprinkler system that has water in the lines is called?
A wet-pipe system.
A fire sprinkler system that has pressurized air in the pipes is called?
A dry-pipe.
Dry-pipe systems are necessary if there is a concern about water freezing in the pipes, otherwise a wet-pipe system is a simpler solution.
At an absolute minimum a roof will need a slope of _____ down to drain pipes.
1/4” per 10’
In the context of Architectural design, the delivery of water and the elimination of waste via water handling systems is part of which type of architectural service?
The Architect’s Scope of Basic Services.
Generally speaking, water will be delivered to where it is needed either from below, via pumping systems, or from above using a combination of gravity and pumping. These two methods may also be called:
Upfeed or downfeed systems.
Why should the plumbing system designer strive to have as few bends and turns in the supply piping as possible?
To avoid having significant friction losses in the supply pipes.
In the discipline of HVAC what are the primary means for delivering heat?
Air and Water.
What does HVAC stand for?
Heating, Ventilation, and Air Conditioning
