Turn pump over and slide impeller assembly out. Take
care to catch any parts that may be loose and fall out.
Inspect impeller, magnetic shaft, and flapper valve for
damage. Wipe all surfaces clean with a soft cloth.
Reassemble pump following the steps above in reverse
order.
Make sure flapper valve is properly seated and oriented
in the correct direction.
Tip: Slide the main pump body over the pump base and
ensure that the pump base is fully inserted into the
pump housing before turning the pump over to install
the mounting screws. Failure to do so may result in the
"flapper" becoming dislodged and limiting the pump's
performance or preventing the impeller from turning.
NOTICE: Make sure O-ring is properly seated before
tightening impeller cover. Do not overtighten cover screws.
