Default Sink Waste venting problem

"Doctor D." wrote in message
I am currently installing a vanity unit sink to replace a pedestal sink in
our en suite.

I have connected the waste to the existing 32mm stub using a pushfit to
solvent weld connector and a new bottle trap via a 90 degree pushfit bend.

The water runs from the sink very slowly indeed. I have held the garden

running flat out over the waste pipe below the bottle trap and it copes

the flow, as did the previous sink. I am wondering if the new sink for

reason can't suck air back quickly enough to drain the sink at a

speed. I have plugged the sink and brim filled it and the overflow

very slowly. (it is possible to overfill the sink with both overflow and
plug hole open!)

I can hear glugging as the water drains, and the water can be heard
trickling down the vertical drop below the bottle trap moving very slowly.

have tried swapping the bottle trap for a P trap but this made no

Has anyone any ideas on this please. I was wondering if anyone markets a
vented trap to allow air to be sucked in - but I suspect this would let
water and smells out!
