Vlog 62A: Poo Sticks October 4, 2016 May 31, 2020Engineering, Life aboard, Vlog 15 This is a follow-up to the last Vlog which was all about narrowboat toilets, hence the odd numbering of this Vlog. In this, I show you how I took out and replaced all the seals, vents and slides inside a Thetford C200 toilet cassette. See Vlog
