I think some of us have been here before. You’ve pulled up to the grey water drain point, started to offload and someone has just pulled up behind you…
After a few mins, you get into a heated discussion with your driving ‘companion’ along the lines of “hurry up”, “it must be empty by now…” and finally to “let’s drive off and come back later”. Of course the other side of the argument is usually “there’s still half a tank to go”, “it’ll be done when it’s done”, through to “they’ll just have to wait!”.
I’ve finally got round to having a look at the waste drainage with hopes of speeding things up. I was going to add new pipes, new valve taps etc etc until I decided to pull the grey tap apart.
it’s easy to do, you just line a lug up to a spacer and pull…comes out nice and easy.
My problem has been two fold. The bit inside the tap that let’s waste out when it’s turned has an exit hole of just 16mm…that’s on a 28mm tap.
Why?!?
Also, behind this choke we’re a couple of bobbles of manky gooey bits stuck that were slowing things down even more.
I’ve enlarged the 16mm hole to the same as the internal bore of the outlet and put it all back together. Also took the time to replace steel jubilee clips with stainless steel ones (paid a bit extra for the original jubilee make, they are far sturdier than the knock offs) as the old ones had completely seized and I wanted to be able to replace the flexible pipe easily if I ever needed to en route anywhere.
What a difference….the van has gone into young stallion mode!
