OPERATION AND MAINTENANCE
Page 5 of 13
Pumping from Draft
NOTE: To get full capacity, quick prime and maintain
pump efficiency:
a.) Position truck as near as possible to water supply.
b.) Avoid humps or sharp bends in intake hose. Make sure
no part of hose is higher than pump intake inlet. (Air
pockets in intake hose may cause loss of prime or erratic
pump action and may reduce pump capacity.)
c.) Make sure all intake connections are tight and discharge
valves are closed.
d.) Immerse intake strainer at least two feet below water
surface to prevent pump from drawing air.(Whirlpools
forming above intake strainer indicate that strainer is too
close to surface of water.)
e.) Make sure intake strainer is far enough from bottom to
prevent pumping sand, gravel or other foreign matter.
1. Prime the pump (see separate).
2. Open discharge valves and increase engine speed to
obtain desired discharge pressure and capacity.
After Pumping ( See “Pumping from Tank” above )
Engine Maintenance
Refer to Briggs and Stratton Operation and Maintenance In‐
structions.
Pump Maintenance
The pump requires no maintenance other than draining the
volute body after each use. If the pump has been handling
chemicals, salt water or dirty water, flush entire system with
clean, fresh water for several minutes to remove all traces of
impurities.
Transmission Maintenance
(PB13G Gear Case Models Only)
Drain and refill with one pint SAE 90 weight gear oil after 100
hours of operation or one year.
Spark Arresting Muffler
Every 100 hours, examine the spark arrestor located inside
the exhaust primer adapter. Clean screen or replace if dam‐
aged. Removal of the spark arrestor will require removal of
the butterfly assembly from the primer adapter.
ENGINE AND PUMP REPAIR
Repairs to be done during the Waterous or Briggs and Strat‐
ton warranty period must be done in accordance with the ap‐
propriate warranty policy.
Engine Repair
If engine service or repair is needed, refer to Briggs and
Stratton Operation and Maintenance Instructions. NOTE:
The control panel, primer, spark arrestor and muffler are not
furnished by the engine manufacturer. Refer to Waterous
Company Service Parts List supplied with the pump for
these parts.
Pump Repair
Pump repair should be done by Waterous authorized ser‐
vice personnel. Alternatively, parts can be purchased from
Waterous Company and installed by any mechanic familiar
with pump overhaul and repair practices and procedures.
