Note The stainless-steel foot valve has an additional O-ring seal near the ball seat.
DO NOT remove this O-ring during

must be ordered separately.
Under normal circumstances this
O-ring will not have to be replaced,
but you must replace if it is
damaged.

approved solvent and inspect the O-ring.
31. If the O-ring is nicked, torn, or broken,
replace with a new one.
32. Using pliers, compress the ball stop and
remove from the foot valve.
33. Remove the foot valve spring and chrome ball.
Note If only using the seal kit, the chrome ball must be reused. Do not drop or dent
the ball or it will be permanently damaged and must be replaced.
