The Wagon Wheel Gasket 5 Spoke is a seal situated near the pump and sand filter, inside the multiport valve. The Wagon Wheel Gasket is 197mm in diameter and fits all Speck, Quality and Collins products. If water is leaking out of the waste pipe when the filter is switched on, it is an indication that the gasket needs to be replaced. To fit the Wagon Wheel Gasket 5 Spoke, loosen the screws on the multi-port valve and remove the old gasket. Ensure the area is clean and dry before adding contact adhesive to the wheel and multi-port valve. Wait for the glue to dry (5 minutes) and fit new gasket. Leve multi-port valve open for 24 hours to allow the glue to dry.
