Frequently Asked Questions

How do I know if this gasket needs replacing?

If water is leaking from around the top cover of the multiport valve on your Waterco S Series sand filter, the top cover gasket is the most likely cause. Turn off the pump and relieve system pressure, then remove the valve top cover and inspect the gasket for cracks, compression set, or deformation. Replace if any damage is visible.

How do I identify which valve variant I have — Grey, Black, or TM?

The valve colour (grey or black body) and the TM designation refer to different generations and configurations of the Waterco 40mm multiport valve used on S Series sand filters. Part 621454 suits all three variants. If you are unsure which valve you have, check the label on the valve body or contact us with your filter model number before ordering.

Does this suit 50mm Waterco multiport valves as well?

No — this gasket is specific to the 40mm multiport valve. Waterco 50mm multiport valves use a different top cover gasket. Check your valve size before ordering.
