EVOLUTIONS 8 - RELAY WATER
PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
The ________ or _______ of the operating pumper (normally 1 st due pumper), upon finding no viable water source transmits signal 10-70 via Department radio and HT and decides on optimum position of the pumper,
OFFICER OR THE ECC
The Officer or ECC of the operating pumper (normally 1 st due pumper), upon finding no viable water source transmits signal 10-70 via Department radio and HT and decides on optimum position of the pumper,
EVOLUTIONS 8 - RELAY WATER
What equipment is needed for relaying water?
2 engines
- 1 supply engine
- 1 operating engine
Sufficient 3 1/2” hose
EVOLUTIONS 8 - RELAY WATER
The next arriving pumper, designated as the ____________, upon hearing signal 10-70 must find a _______________.
WATER RESOURCE UNIT AND MUST FIND A VIABLE WATER SOURCE
The next arriving pumper, designated as the Water Resource Unit, upon hearing signal 10-70 must find a viable water source.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
What size connection should the supply pumper use in water relay operations?
If water relay is necessary, the 10’ or 35’ hydrant connection is connected from a hydrant to the Supply Pumper.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
The necessary lengths of 3 1/2 inch hose are stretched from a 3inch outlet of the supply pumper to where?
3 inch gated inlet on pump panel side of operating pumper

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
Both the supply pumper and operating pumper remain in the VOLUME position, except when?
At Standpipe operations where head pressure needs to be overcome, the Supply Pumper remains in the Volume position and the operating pumper must be in the Pressure position.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
Relay water evolution:
- Supply Pumper ECC opens the hydrant fully, engages the pumps, primes, and then sets the reading on the Pro-Pressure Governor to match the idle pressure shown on the Pump Pressure Gauge.
- Supply Pumper ECC tells Operating Pumper ECC they are ready to send water, then upon confirmation, opens 3” discharge gate fully
- Operating Pumpers ECC leaves the gated inlet closed while opening the drain to the gated inlet, When good water flow is observed flowing through the drain, close drain
- Operating Pumper ECC slowly opens 3” inlet gate fully note Intake Pressure gauge reading (read aprx 100–125 psi) primes and note Pump Pressure Gauge ( 50-60 psi greater than the Intake gauge)
- Operating Pumper ECC then sets the reading on the Pro Pressure Governor to match the idle pressure on the pump pressure gauge and begins fire line operations.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
If the ECC of the operating pumper has already supplied water to handlines via booster tank prior to being relayed water, what must he do to accommodate the increasing pressure?
If the ECC of the Operating Pumper has already started supplying a handline from booster tank water then open intake gate slowly while adjusting individual discharge gates to accommodate the increasing pressure.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
If the Intake pressure gauge reading does drop below 15 psi on the Operating Pumper, then the ECC of the Operating pumper should? .
If the Intake pressure gauge reading does drop below 15 psi on the Operating Pumper, then the ECC of the Operating pumper should request the Supply Pumper to increase throttle (tap-up pro-pressure governor) in 10 psi increments as needed.

PUMPERS EQUIPPED WITH PRO PRESSURE GOVENORS: OPERATION
If the Supply Pumper’s Intake pressure gauge drops below 15 psi, the Supply Pumper ECC should?
If the Supply Pumper’s Intake pressure gauge drops below 15 psi, the Supply Pumper ECC should contact the Operating Pumper ECC and the Incident Commander and inform them that the hydrants supply limit has been reached.

Pumpers Manufactured Pre 1997: OPERATION
For apparatus manufactured prior to 1997 without a Pro-Pressure Governor, the Supply Pumper should send water to the Operating pumper at?
For apparatus manufactured prior to 1997 without a Pro-Pressure Governor, the Supply Pumper should send water to the Operating pumper at idle pressure, opening the discharge gate fully.

Pumpers Manufactured Pre 1997: OPERATION
If the Operating Pumper ECC notes the intake pressure is greater than 150 psi or the automatic intake relief valve discharges (this should happen when the inlet pressure reaches 150-175 psi), he/she should communicate with the Supply Pumper ECC to insure?
If the Operating Pumper ECC notes the intake pressure is greater than 150 psi or the automatic intake relief valve discharges (this should happen when the inlet pressure reaches 150-175 psi), he/she should communicate with the Supply Pumper ECC to insure he/she is in the Volume position.
