Wet standpipes are typically found in very tall buildings, providing water to firefighters.

Fire system piping is usually painted red to indicate its purpose.

A curb stop is a control valve located between the street and sidewalk, managing water supply.

Curb stops are used when water needs to be controlled, such as during repair or maintenance.

A corporation stop is required to control water flow when accessing a main pipe under pressure.

Accurate cutting of pipe threads ensures compatibility with fittings and follows American Standards.

Fire fighting apparatus refers to tools like fire trucks that require water supply from systems like standpipes.

Control valves are essential in ensuring a safe and efficient water supply for buildings.

The process of sloping pipes downwards for water flow towards discharge points.

Conditions that ensure efficient water removal and prevent contamination in buildings.

The specific flow rate needed by a wall hydrant, usually measured in gallons per minute (gpm).

The specific flow rate required by a bathtub faucet, usually measured in gpm.

The specific flow rate required by a shower head, typically measured in gpm.

The specific flow rate required by a sink faucet, measured in gallons per minute (gpm).

The flow rate required for a drinking fountain, usually measured in gpm.

A short piece of pipe, less than 12 inches long, threaded on both ends.

A short piece of pipe less than 12 inches with threads on both sides.

A short pipe whose threads at both ends meet without space.

A pipe whose thread at both ends leaves a small space between them.

The minimum nominal diameter for peak water service is ¾ inch.

The tin content in a brass fitting is 5%.

The zinc content in a brass fitting is 25%.

The copper content in a brass fitting is 85%.

The recommended fall for 4 inch pipes and larger is ½ inch per foot.

The suitable gasket material is rubber.

Rubber or asbestos material is suitable for gasoline flange unions.

The lavatory or wash basin is the smallest fixture considered.

The ideal size is 100 mm for underground or slab installation.

A 100 mm x 3.0 m pipe is to be used in drainage with a 4.40 m face-to-face distance.

Each joint requires 16 grams of solvent cement.

If solvent cement is 80.00 Php/gram, calculate the total based on grams used.

Fast waste removal with minimized leakage and stoppage is essential.

Using a gate valve on a lawn sprinkler is not ideal due to its bulkiness and tendency to fail in closing tightly.

Basement water supply must be properly graded to prevent water pressure issues and damage.

Gate valves should be used after the entrance of the street water main or in main supply lines for better control.

The vacuum breaker should be installed 6 inches above the flood level rim to ensure proper operation.

Mechanical drainage is necessary when sewage volume is high or gravity cannot achieve drainage effectively.

Wrought iron pipe is commonly used as leaders in tall buildings due to its strength.

Cast iron pipe is recommended for underground drains within buildings for its robustness and durability.

Excessive sewage volume can require pumps or ejectors for effective management in buildings with basements.

Uses yellow background with white lowercase letters to indicate non-potable water.

Protects potable water supply with an airgap and a vented backflow preventer.

Requires either a double check valve backflow prevention assembly or reduced pressure principle prevention assembly.
