Grey water

Sorry if you all think I'm really stupid but, I have just bought a Sussex duo. In the owners manual it says that the grey water drain is the one nearest the back of the van this is the blue pipe directly under the water fill. The one nearer the front is a grey pipe. Am I missing something? My assumption is that grey would indicate dirty and blue would be clean. Have just sanitised and filled and put the sterilising stuff in and want to just drain any surplus from grey waste. Not that I don't believe the manual just don't want to lose all my fresh water. Thanks

There's no such thing as a stupid question 

I don't know your van, but certainly both of my previous motorhomes and my current Auto-Sleeper have blue pipes & taps on the fresh water drain and grey on the grey.

If there's not much in your waste tank, try the one you think it is.  The worst you're going to do is have to top your fresh up, but at least you will know that a previous owner hasn't mixed them up.

I've got a Warwick Duo, which I believe is the same as your Sussex. The waste water drain is the one nearest the front and has the grey pipe. I am pretty sure that your manual is wrong.

Hi and welcome to the forum from Dunnet bay

The confusion may arise from the nomenclature of grey and black water as opposed to fresh water, gray water is what comes from the sink and shower as possessed to black water the originates from your bodily functions.

Thank you all for your help

It doesn't normally take much effort, but that confused me, I didn't realise Auto-Sleeper had the option of 'black' waste. I thought that was into the realms of SOG systems or RVs

Hey 'op someones just swallowed a dictionary  I don't know of any A/S that has anything other than a Thetford , Fiamma or other cassette toilet system as apposed to a large holding tank. Not even the RV type German Commodore has one as standard. The only European 'van I know of that used to use the holding tank system is Laika but the perpendicular pronoun will bow to superior knowledge.

My grey water from my grey hose is now on my drive, doh.  Tried fiddling with the tap to put an hose extension on it and it came off in my hand.

    Excuse my mirth. It's nice to know others have minor setbacks

absolutely no problem

Just to add to the confusion my gray water emptying pipe is black, but I expected that as the previous owner has undersealed everything, including the mud with a black bitumen substance.
