New sink (different position to previous) , what do I need/best way to connect to the wastepipie

[Dutch85]

We've replaced the kitchen sink and how to position it in a different location to the previous.
What do I need to get this connected to waste pipe? I need to connect the washing machine wastepipie to it also. Is flexi the way to go?

Unfortunately, you may have fallen victim to what is a regular issue when a sink is replaced and the outflow pipe ends up being too high to take the outlet from the trap system for the sink.

That being said you may just get away with it, using a P trap and cut the elbow off the outflow pipe. The condensate saddle is complicating things though, depending on how far back the outflow pipe needs to be cut to properly connect with the trap.

Firstly get a trap and attach it to the sink waste and see where it is with levels and lengths. Worst case is the outflow waste pipe (through the outside wall?) will need to be lowered

Thanks for the reply. Yes, the wastepipe is through the wall. If it needs to be lowered it would involve drilling through the brickwork?

Unfortunately yes. I would get a trap fitted to the current and see how it all lies first. As suggested though, if you're lucky, you might just get away with it as it is.

Mcalpine do an adjustable trap which gives some vertical leeway.

OK if you look at a standard P trap - you can see that the outlet is almost level with the waste connection, so given you waste pipe is a few mm lower than the waste, the height may just work.

The issue is the offset as the outflow isn't in line but you may still get away with it as a p trap can be swivelled to many different positions to aid in alignment. The outflow pipe may need adjusted a little for length to meet the compression end properly and that's where that saddle clamp may get in the way a little when adding a coupler once the elbow is removed
