The water seal is what keeps the smell out · review
An Italian-made space-saving trap that states it is inspectable — meaning it opens to be cleared rather than being taken apart.
The bottom line Simple, openable and sized for either wall pipe. It is sold as space-saving without saying how much space it saves.
A white plastic space-saving basin trap with a 1 to 1¼ in connection and a Ø32 to Ø40 outlet, in a single-chamber design stated as inspectable.
A trap fills with hair and soap at the bend. Inspectable means there is a way in — a cap or an access section — so it can be cleared where it hangs.
Without that, clearing a slow basin means undoing both connections with a bowl underneath and a torch in your teeth.
Ø32 to Ø40. Either common European waste size. If the pipe is already in your wall and you have not measured it, this fits regardless.
It is described as space-saving, and no clearance figure is given.
One trap in this hub states that it fits where there is less than 15 cm under the basin. That is what a space-saving claim looks like when it is a specification rather than an adjective.
Water seal depth. Not published by any trap in this catalogue.

That there is an access point — a cap or a removable section — through which the bend can be reached and cleared. Without one, clearing a blockage means undoing both connections and taking the whole trap out over a bowl.
It is simpler. Fewer chambers means fewer seals and fewer places to leak, and less to go wrong over twenty years. What it does not do is hold back as much debris before the flow slows.
