I’ve got 2 round sinks to install in a standard 1000mm sink unit. I bought some 40mm

drainage pipe and a selection of push-fit elbow connectors and a t-piece. What I was planning to do was direct the two sinks drainage into the t-piece and then route that to the main

drainage point where it used to exit in the bottom corner of the kitchen. I’m not sure about the sink trap though (is that the right word?, I used to call it a U-bend), is it

possible for me to have just one of these further down the system, i.e. after I’ve linked the pipes, or do I need one for each sink?

McAlpine waste kits are

available specifically for the purpose of linking two wastes as you describe and these include a trap.

You can complete the installation using the method you describe but this is best achieved with seperate traps for each sink.

My own preference for waste pipe installation is to use solvent weld pipe and this, in my opinion, offers more protection against leaks and will suffer the future inevitable knocks

without developing a leak due to it;s greater rigidity.

McAlpine, okay I

think heard that mentioned somewhere but I didn’t realise what it was. I’ll see if I can exchange all the push-fit stuff for one of those and some solvent pipes/connectors. I’ve

already got some of the solvent as I had to repair some of the existing pipes. The reason I got the push fit ones was just because it looked easier to put together!

Thanks Tim 8)
