4. Pressurize pump.
LEAK TEST PRESSURE
Maximum 70 kPa (10 PSI)
5. Pump must maintain this pressure for at least
5 minutes.
NOTICE
Repair any leak. Failure to correct a
leak will lead to premature wear of pump com-
ponents.
NOTE:
If there is a pressure drop, spray soapy
water around cover. If there are no bubbles, im-
peller shaft, impeller shaft seal, or jet pump hous-
ing is leaking through porosity and has to be re-
placed. Jet pump unit has to be disassembled.
NOTE:
There may be 2 or 3 bubbles coming out
from the seal on the impeller side. This small leak
is acceptable. Leaks from other areas must be re-
paired.
