The earlier, bench type Thetford cassette toilets had a transparent sight tube which doubled as a water level gauge and an emptying facility.  I can only conclude that not continuing this theme on the later units is simply penny-pinching.

Ouch, Bob!  If you bought the van from a dealer, that omission of the plug was very poor PDI.

Incidentally, when my van goes in for service I attach a sticker over the plug saying "Do not remove".  I have reasoned that, the more frequently this plug is removed, the more likely it will one day come out by itself.

We did buy the van from a dealer.  They tried to say it must have come out while travelling.  They did give us a new one, and we have not had a problem since.  Although I am sure the dealer did not put one in.  If it had popped out it would have been in the casette locker, but it was nowhere to be seen.  Since then we have changed the van, and still had no problem.  You live and learn.
