Ok not good with washing machines myself, a friend has had one installed in their flat, but....

There is no U-Bend installed for the Outlet / Drainage pipe, is it a neccesity? - At present the rubber hose thingy goes to the U bend in the sink, theres no adverse smells or anything, they are gettin paranoid :)

Any advice welcome!

the u bend is a trap and you should have one really..

Edited to add that if the rubber hose connects onto the side of the trap under the sink then one isnt required.

David,

hmmm interesting....

I 'think' the rubber outlet hose attatches to the bottom of the exisiting U bend so it sounds like it does need one then?

Cheers

for this type of installation you can use a proper washing machine waste kit,which includes standpipe and trap,or like your mates,connect via a small connector on the sink waste.
The sink method should only really be used where its hard to run a separate waste away from the washer.
The trouble with the sink method is that you can hear all the water gushing down the waste pipe because of the sink plughole.

the ideal way is for a waste kit,standpipe up,trap, then through a outside wall to a gully or the soil pipe(depending on drainage type).But you'l find you usually struggle for space behind a washer and usually the trap kit needs to go at the side of the washer.

Yeah, what scooby nutter says :D

I think you're supposed to use 40mm wastes for washing machines aren't you? Not got much experience, but I know that our extra "inlet" on the sink waste is only suitable for a dishwasher...

40mm for baths and washing machines... bigger cant hurt..

David

Cheers for the replies guys :)

Spoke to my mate who's 'working from home' yea rigthyo lol, he reckons there is bugger all room to install anything let alone another u bend and all the other suggestions, another prob is that he's on a 2nd floor flat (Rented) So plumbing thru the wall would be a little difficult, He's just a bit paranoid that its going to start stinking / go wrong with his current setup, but after a month I think it would be smelling etc right now which it isnt, could be a case of 'If it aint broke then dont fix it' methinks :)

What could happen if you're using too small a waste?

Guessing here, but in short you can't flow enough water out of the washing machine, so it'll sit in the washing machine for a bit longer. Or the washing machine pump will build pressure in the outlet pipe.

You shouldn't get any smells, but the washing machine might not like it...

if you look at the pipe coming out of the machine its about 30mm.as long as your pipe is bigger than this i dont suppose it matters.
But we always use 40mm wastepipe for a washer/dishwasher installation

The washing machine MUST go in the sink side of the trap.

If not you could have problems with smells etc etc.

All the best
