That’s a lovely neat install, Chris. I particularly like the right-angled joint.
I didn’t have a blanking board fitted to my Exsis so I didn’t have to fit round it. But so that I don’t have to reach into the depths of the Exsis to turn on/off the waste tape, I fitted a very handy 40cm flexible pipe onto the waste outlet, that I then put a good quality tap onto. The upsides are that I don’t have to go to the boot area to operate the waste tap and I can point the waste outlet in the best direction very easily now. The downside is that the tap gets grubby and hence my fingers do too!
Thanks again for showing us your SOG installation.
