Trap / Waste for vanity unit

[Justice League]

I am looking for a basin waste and trap. I know the simple plughole and chain wastes are possibly the easiest to manage with but whats the next best - click clack ones?

As to traps - best to stick with the tried and tested S or P or go for a Macvalve?

Mcalpine mini bottle trap (e10)

I would go p-trap, especially if it goes into a soil pipe as it has a deeper seal (76mm), also has good adjustability.

Strictly speaking the shallow seal (38mm) traps shouldn’t go straight into soil pipe, should go via gully or hopper, but in practice they always seem fine.

Always go 76mm if you can. I’m currently dealing with an issue of smells. Did a smoke test on the stack and both the tiled in shower and bath are passing.

The waste pipe goes into a hopper not directly into a soil pipe. Is the seal the depth of water in the trap?

Yes. In that case you can use a physically smaller trap if you wish.

Such as the mcalpine e10 mini bottle trap that Shaun suggested ages ago! He must have known you had a hopper
