preferably a garden hose if possible. Return it to the filter housing ensuring that the U-shaped gasket fits securely to the bottom of the strainer. Make sure that the strainer head gasket is secure.

Reposition the strainer cover on top of the filter housing.

On those models with a band clamp, replace the band clamp around the strainer cover and housing latching the T-bolt. Then push the latch handle towards the filter housing. The T-bolt latch does not need adjustment when installed. It is set at the factory for proper clamp compression.

Bolted cover models require a torque sequence as follows: 12:00 to 6:00, 3:00 to 9:00, 11:00 to 5:00, and 2:00 to 7:00. Bolt torque requirements are: 3/8” bolts (15 to 25 ft.lbs.), ½” bolts (45 to 55 ft.lbs.), and 5/8” bolts (80 to 100 ft.lbs.).
