What bits needed for 1.5 bowl waste connection?

Connectors to T the 2 outlets, bring the single leg of the T forwards, go round 180 deg. and stick in a HepVO trap. Hardly any wasted space and no underused trap on the half-bowl to collect crud. As far as I'm concerned, there's little point in having more than one trap in a room if all factors allow just one - 'isolating' things that are all open to the air is a waste of time.

Firstly, the smaller sink bowl is generally higher than the main bowl. You can get adjustable traps to compensate for this (get 2, so they can be adjusted up and down):

You will need around 1 metre of 40mm waste pipe, 1 bit from each trap to a T piece join, then from the T piece to the outlet pipe. Get a compression fitting to join the 2 bits, as they may be a slightly different size.

Full packs are available from Screwfix/Toolstation, but IMO they are usually pretty rubbish, and their pipes are always a non-standard, meaning extra compression fittings may be needed. Alan.

Yes, I realised after I posted that the normal way to do it is with just one trap.

I probably mostly know this already but as it's remote I'd like to be sure I have all I need.

What bit's do I need to connect up a 1.5 bowl sink to the waste? The sink comes with its waste connections with standard plastic threaded connectors so:-

Two traps to connect to the sinks A length of waste pipe with a T in it between the two traps Connect to the existing waste pipe

I guess I'd better take some converters as I'm not sure what size/type the existing pipe to the drain is.

Can on normally get away with just a short horizontal length and a T between the two traps? Is this the usual way to do it?

-------------------------------------------------------------------------------- B&Q et al sell a kit containing all the bits you need (in the kitchen section). You will also need the patience of a saint & a large tube of LS-X.

Bloody nightmare to get them in without leak's IME.

Leaks from where, the sink skin connection or the pipework?

I fitted my new 1.5 sink yesterday and didn't have a single leak. Must lead a charmed life!

Even better, not once did I empty the trap down the sink I'd just taken if off. I've lost count of how many times I've done that before.
