    Default Are waterless traps any good

    Iím thinking of getting waterless traps installed in 3 bathroom vanities. The reason is that 2 are very small vanities and I would like them to have functional drawers, which a p trap will preclude. The other one not so important.

    I emailed our plumber (this work needs to be done by a licensed plumber if I want an OC) and he was vague on the idea but would install them if I sourced them. So has anyone got any experience of them, have an opinion, know if there are any regulatory pitfalls?

    Example

    Plumbers tend to use them in locations where a normal trap could dry out, such as for a tundish picking up drains from aircons that might not be turned on for 6 months of the year. They don;t tend to replace conventional water traps with them though.

    first thing that comes to my mind is that can wear out creating a hole in it letting gasses through

    Don't know. Cost perhaps? Or possibly they are not the best for constant use applications?
