Waterlock

[zoidberg]

I'm about to buy a new waterlock, and discover that, besides Vetus, there's a new kid on the block...

Centek Vernalift GRP Exhaust Waterlock (Top In & Out / 51mm)

Does anyone here have any experience of these - merits and no-nos....?

Scarcely new. Centek has been making wet exhaust components for over 50 years. US-based, so Imperial sizing, which might not always tally with European installations.
Good reputation. Their emphasis was (don't know if it still is, although your example clearly is) on GRP components which, if nothing else, are easier to repair than injection-moulded plastic. Equally, it perhaps doesn't offer the precision needed for the adjustability of some Vetus designs.

Which waterlock did you buy in the end and did you get the results expected?
