CLEAN RECOVERY TANK DRAIN
Debris and sand accumulation in the drain valve can damage the valve or prevent it from closing completely.
This will result in dirty water leaking from the valve. Use of the Hydro-Filter and regular cleaning of the
recovery tank will help prevent this, but occasionally the drain valve will require cleaning or replacement.
Unplug both power cords and drain the recovery tank before attempting to service
the drain valve.
• Unscrew the nuts and remove the four bolts holding the valve assembly to the flange attached to the
recovery tank. Unless the flange is damaged, it does not have to be removed from the tank, even when
replacing the drain valve.
•
Separate the valve body, outlet adapter and gaskets from the flange.
• Examine the valve body for wear. Check the valve slide
for deep scratches. Deep scratches will allow water to flow
past gaskets and leak from valve. Replace valve if needed.
• Examine the gaskets and replace if cut, torn or deformed.
• Raised, rounded side of gasket goes toward valve slide.
Larger flat sides seat on ring on flange and outlet adapter.
Sand and debris will collect in the bottom of the valve
body and prevent the slide from going down and seating
properly.
•
Clean debris out as needed so slide can move to bottom.
• Rinse valve body and reassemble valve body, gaskets and
outlet adapter, and place assembly back onto flange fitting.
• Replace four bolts and tighten evenly to secure assembly
to flange. Do not over-tighten bolts.
Remove four bolts holding valve
assembly to flange fitting Unless damaged or leaking between tank and flange, the
flange fitting does not have to be removed
