Frequently Asked Questions

How do I know if this O-ring needs replacing?

If water is leaking from around the pump lid on your Waterco Aquastream pump, the lid O-ring is the most likely cause. Turn off the pump and relieve system pressure, then remove the pump lid and inspect the O-ring for cracks, flattening, or deformation. Replace if any damage is visible.

Is this the same O-ring as the Turbotuf or Supatuf pump lid O-ring?

No — the Aquastream pump lid uses part 635052, which is specific to the Aquastream range. The Turbotuf, Supatuf, and Hydrostorm pumps use a different lid O-ring (part 63151). Always confirm your pump model before ordering.

Should I lubricate the O-ring when fitting it?

Yes — apply a small amount of silicone-based O-ring lubricant (not petroleum-based grease) to the O-ring before fitting. This helps the O-ring seat correctly, prevents pinching during assembly, and extends its service life.
