SECTION 313.008 TANK SUPPLY FROM ANOTHER ENGINE
PURPOSE
To define standard operating procedures for supplying an attack pumper using
another pumper’s water tank.
APPLICATION
The need for an external water supply and how it is accomplished must be determined
during size-up. It is the responsibility of the driver/operator to anticipate and confirm
plans for a water supply with the company officer prior to assignments being given to
incoming apparatus.
OPERATIONAL POLICY

OPERATIONAL GUIDELINE
This section intentionally left blank.
PROCESS
1. Spot apparatus and prepare for standard pump operations. See Training and
Equipment Manual Section 313.005, Standard Pump Operation.
2. Supply reel line(s) or attack lines as needed. See Training and Equipment
Manual Section 313.006, Supplying Small Hand Lines.
3. Properly set the Relief Valve. See Training and Equipment Manual Section
303.004, Pressure Control Valves, and Section 313.006, Supplying Small
Hand Lines.
4. Identify current water tank level status. Report any potential risk of running
out of water immediately to the company officer or the IC as necessary.

5. Anticipate the need for securing an alternate water source. Attach a 50’
section of 2-1/2” hose to the auxiliary intake and deploy it alongside the
apparatus for tenders or other engines to connect to.
6. If spotting the apparatus to provide tank water to assist the primary pumper,
take into consideration:
a. Park the apparatus close enough to the attack pumper so that
a single 50’ roll of 2-1/2” hose reaches from your discharge to
their intake.
b. Avoid parking too close to the attack pumper’s ladder access.
c. If not needed for scene lighting, turn the headlights off.
7. Securing your supply with another pumper or water tender:
a. If you are without help, i.e., a second engineer, use extreme
caution when leaving your pump panel. Never put yourself in a
position where you cannot respond appropriately to address
imminent problems.
b. Connect the female end of the pre-attached 50’ 2-1/2” hose to
a discharge of the supply pumper or water tender.
8. Prepare the supply pumper for standard pump operations.
a. Pumper: See Training and Equipment Manual Section
313.005, Standard Pump Operation.
b. Water Tender: See Training and Equipment Manual Section
310.010, Water Tenders.
9. Open the appropriate discharge of the supply apparatus.
10. Keep the throttle at an idle. This should generate approximately 50 psi on
the discharge gauge being used and 20 to 50 psi at the attack pumper’s
intake gauge while water is flowing.
11. Open the auxiliary intake valve on the attack pumper slowly.
Simultaneously adjust the throttle to compensate for incoming pressure.

b. Monitor the intake pressure gauge and the pump discharge
pressure (PDP) gauge simultaneously. As soon as you see
intake pressure begin to rise or can hear or feel water passing
through the intake valve, look at the PDP gauge and anticipate
throttling down to compensate for incoming pressure.
c. Throttle down slowly as pressure begins to rise to maintain a
constant PDP. Anticipate throttling down approximately 50 psi
(equivalent to the incoming pressure).
d. Open the auxiliary intake valve all the way.
12. Open the tank-fill valve enough to slowly fill the tank, but not enough to
adversely affect PDP. Adjust throttle simultaneously to compensate for lost
PDP as necessary. Visually ensure the tank is filling. Close the tank-fill valve
when full; adjusting throttle simultaneously to compensate for gained PDP as
necessary.
13. Before the supply pumper’s tank is half empty, make provisions for another
supply pumper, a water tender, or an LDH from a hydrant for use.
14. Depending on how much water is remaining in the supply pumper, continue
with one of the following procedures:
a. If the supply pumper is nearly empty:
i. Slowly close the auxiliary intake to the attack pumper while
simultaneously throttling up to compensate for the loss of
incoming pressure as necessary.
ii. Return to the supply pumper, disengage the pump, and
disconnect the 2-1/2”.
iii. If needed, secure another water source.
b. If staying connected to the supply pumper for its remaining
water, the following may be a consideration:
i. When pumping from a limited tank-water supply, avoid
spilling water onto the ground unnecessarily. Due to wear,
many of the tank-fill valves leak (sometimes significantly)
under pressure.

ii. On hot days you may need to intentionally leave the tank-
fill valve (or any other discharge valve and / or drain)
cracked open to assist with keeping the pump cool.
Therefore, circulating water to and from the tank is the
preferred method used to keep the pump cool. This same
technique can be used to avoid spilling water onto the
ground in the case of a leaking tank-fill valve.
15. Return to the supply pumper and disengage the pump by placing the
transmission in neutral. The supply pump can be left in gear and the
2-1/2” discharge valve can be left open. Receiving additional water
from the supply pumper is now as simple as placing the transmission
in Drive and repeating the procedures previously stated associated
with opening the auxiliary intake and tank-fill valve. Use the supply
pumper to keep the attack pumper’s tank filled as necessary.
16. If needed, secure another water source.
