THE MULTIPORT VALVE
"FILTER": water enters the Bead lter at the lower inlet and goes upward through
the beads and exits out of the vessel via the top spray bar to return to the pond.
"RECIRCULATE": With the "RECIRCULATE" feature you can bypass your lter and
ow the water from pond to pump to multiport and back to pond. This comes in
handy when you are treating the pond with medication.
"WASTE": allows the water to bypass the lter and go directly to waste, such as
when you are performing a backwash cycle. You can also use the waste setting to
vacuum out your pond without the garbage going into your lter, it bypasses the
lter via the multiport and goes out to waste.
"RINSE": The rst time we use the RINSE feature to wash the beads with the blower
which forces huge amounts of air into the vessel and since air rises in water, the
beads are broken apart by this action, making a thorough backwash easy to
accomplish. After the backwash function we use the RINSE feature again but now
with water instead of air. It is impossible to get every little bit of debris out of a
lter and this causes these small particles to exit in the waste line instead of going
back into the pond.
"BACKWASH": In this position we let the pump run until the water in sight glass is
clear (normally 1 to 2 minutes). The water enters the lter from the top spray bar
and exits the vessel at the lower pipework and goes out to waste.
"CLOSED": Valve closed. Never use this position with the pump running.
