Leaking from waste water pipe at u-bend under sink

[lucy]

I have a slight leak from my waste pipe connection under the sink. The previous homeowner installed the kitchen and the pipes are different to what I've seen before. There is a grey pipe which sticks up and I've simply pushed the waste pipe onto that, as there's no other way to do it. 

Should I just fit a jubilee clip around the waste pipe, or do the pipes need changing to something more standard?

I normally use one or two plastic cable ties to fasten the drain hose on. I pull them tight using pliers and then cut off the excess cable. Before cable ties, I used to use good old-fashioned jubilee clips. You would need to make sure you had the right size to be able to fit them nicely.

You might also consider using some plumbers tape to wrap round the plastic pipe first. Don't over tighten a jubilee clip onto a plastic pipe though.
