Hi, I have just had a new sink fitted and I am a bit concerned as to the way the waste has been fitted. Please could you comment as to whether it is good or whether there are any issues that should be rectified

Outlet is too high, looks like this bit has been added to make it reach the waste pipe. Waste pipe needs to be lower, and appliance hoses should rise up then down into the waste.

That's a hash up of different pipework and bits by the looks of it. Where did the sink and waste stuff come from?

As suggested - the outflow pipework is too high, meaning the waste pipework will always be full of water or it will drain back into the appliance that's connected far left. It needs re-done with the outflow pipework lowered to accommodate the waste, the waste kit levelled and the P trap fitted properly without the extension
