Hydrant failure can result from

Damaged valves or connections

Broken water mains

Greater demand than the system can provide

Dead-end water mains

Closed isolation valves

Restricted mains

Frozen pipes or hydrants

An alternative supply may be needed if a hydrant fails to supply sufficient volume or pressure.

Water drains through a valve at the bottom

Dry-barrel hydrants are designed for use in climates with freezing temperatures.

A–160

Water in the hydrant at all times

Horizontal compression valves usually at each outlet

May have a control valve on top that controls water flow to all outlets

Wet-barrel hydrants are usually installed in climates without prolonged periods of subfreezing weather.

All hydrants must be opened and closed slowly.

A–168

Main valve is located below the frost line

Hydrant barrel is normally empty

Turning stem nut counterclockwise allows water to flow into the hydrant

Turning stem nut clockwise shuts down the hydrant

Additional precautions must be taken in areas where subfreezing weather is common

Be aware of considerations that are specific to dry-barrel hydrants.

A–169

(Cont.)

When shutting down a dry-barrel hydrant, it is important to verify that water is draining out.

A–170

Test the water level

If the hydrant is draining, a vacuum should be felt on the palm against the discharge — If not, repeat the process

If hydrant is still not draining

• Drain hole is probably plugged• Notify water authority to inspect the hydrant• During winter, the hydrant must be pumped

Driver/operators must be able to make soft intake and hard intake connections to fire hydrants.

A–171

Soft intake

Hard intake

If the hard intake is marked FOR VACUUM USE ONLY, do not use it for hydrant connections and pressurized systems. This type of hard intake is only for drafting operations from a static source.

A–172

REVIEW QUESTION

What are two types of hydrant connections?

A–173

• Lack of public water distribution systems

• Systems with inadequate water volume and pressure

Areas where mobile supply

operations must be performed

• Connecting and placing hard-suction hose for drafting

• Deploying a portable water tankSkills

Driver/operators must be familiar with mobile water supply operations.

A–174

In a forward lay, the hose is deployed from the water source to the incident site.

A–175

Communication is essential

Local SOPs will dictate the method used to connect hose to the hydrant in a forward lay.

A–176

Signal driver/operator that it is safe to proceed

Anchor the hose

Wrap finish section around hydrant base

Remove hose

Four-way hydrant valves may be used when making a forward lay.

A–177

(Cont.)

Four-way hydrant valves may be used when making a forward lay.

A–178

In a reverse lay, the hose is deployed from the fire scene to the water source.

A–179

A wye is often used in reverse lays to create two smaller attack lines.

A–180
