Thetford Water Diverter (C250 / C260 Series Toilets)

This small plastic water diverter sits inside the flush-water system of Thetford's C250 and C260 series cassette toilets, routing water from the internal fresh-water tank and pump through to the bowl flush jets each time the unit is flushed. It's a common wear item, over time the diverter's seals and plastic housing can crack, warp or clog, causing weak, uneven or leaking flushes. Replacing it is a straightforward internal fix that restores proper flush pressure without needing to replace the whole toilet.

• Q: My toilet flush is weak or leaking from underneath, is this the part I need?
  A: A worn or cracked water diverter is a common cause of weak flushing and internal leaks on C250/C260 series toilets, so this is a good first part to check and replace.
• Q: Does this fit my C263-S?
  A: Yes, the C263-S is one of the C260 series models this diverter is designed for.
• Q: Is this easy to fit myself?
  A: It's an internal component accessed by removing the toilet's water tank/pump housing, so most owners with basic DIY skills and the toilet's service manual can fit it, though it is fiddlier than an external part.
• Q: Does it come with a seal?
  A: The diverter is supplied as the plastic valve component; check your existing seals for wear and replace them separately if needed.
