Hi all, I was bought one of these the other month by the in laws as a moving in present. Am trying to plumb it in but the only location for it is 3 or 4 feet from the sink drain. The manual states NOT to extend the drainage hose. Looking online is an absolute minefield of opinions, whilst my installation guide is sparse of info. The general consensus is that you need to make a loop, or an air gap in the hose to prevent reverse siphoning or gasses/congestion from the sewer coming the other way (and to ensure the pump operates correctly?) However, looking at my drains (which were re-done by the former owners) both my washing machine and sinks 2 inch pipes simply spill into what looks to be a 6 inch waste sewer which goes off and joins the one from my toilet at a later point. There are warnings online about keeping 'surface water' and 'waste' pipes separate, I'd hate to think i'm contributing to any kind of pollution but from what I can see my gutters down pipes are embedded into the ground separately? The only option I can think of (which falls in line with the installation guide) is to install a length of 2 inch piping - its then a case of whether I join to the existing sink waste or via its own exit? Can anyone offer any advice on what I should be doing? Any plumbers offer a quick fix based on my circumstances? Apologies for the waffle, but I thought I'd put everything I've encountered in the first post! Thanks 1/6/2010.a new era.we made it everyone!!!lets get the ball rolling for another 105 years of proud history.thank you cpfc2010. palace forever.eeaaaaaaaaaaaaaggglless!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

From my experience (amateur only) and watching the guys plumb in my dishwasher.... I think you are right. If you can have the dishwasher waste with it's own exit that would be best... you might compromise the sink waste by attaching the dish washer to it. Best to have connections to sewers outside than in.

Although it would be best entering the soil sack directly due to the amount of water passing through if both the sink waste and machine waste are operating at the same time. PALACE TILL I DIE!!!

Of course you can, but it makes life simpler for the dishwasher waste to be on its own rather than having spaghetti junction of waste-pipes under your sink and the point you made about volume of water from both sources.

Yeah, personally I would plumb them into the same waste. I would run the 40mm pipe out of the sinks trap and when you get to the Washing machine waste I would then use an increaser to up the pipe to 50mm so that it allows more flow of water. This will only require one extra pipe so it wouldn't be a spaghetti junction under your worktops PALACE TILL I DIE!!!
