Waterco Sand Filter Multiport Valve 40mm 228042

The Waterco 228042 multiport valve fits the following sand filter models: D400, SD500, SD600, S600, S700, T400, T450, T500, T600, F400, F450, F500, and F600. It also suits all Aquaswim models. It is a 40mm threaded (screw-in) unit and does not suit filters that require a clamp-style multiport.

The Waterco 228042 multiport valve has 40mm outlets, which corresponds to a 50mm outer pipe diameter. Before ordering, measure your existing pipework or check your filter manual to confirm this matches your current setup.

Yes. The Waterco 228042 multiport valve comes complete with unions and O-rings, as well as the tank O-ring. A pressure gauge is not included. This means you have everything needed for a standard replacement installation without needing to source additional fittings.

Water leaking from a Waterco multiport valve is typically caused by a worn rotor or handle that can no longer maintain a proper seal between filter cycles. This allows water to escape through the backwash or waste line even when the valve is set to Filter. Replacing the multiport valve with a new 228042 unit restores the seal and stops the leak.

The Waterco 228042 is a threaded screw-in multiport valve. It is not compatible with sand filters that require a clamp-style valve. Check your existing filter head to confirm whether it uses a threaded or clamp connection before purchasing.

Yes. The Waterco 228042 Top Assembly Multiport Valve is a direct replacement for both the grey and black hexagonal Waterco valves, provided the filter uses a threaded screw-in connection.
