The drain can be fitted with a sieve insert (model 4958) to collect dirt.
Advantix drains can be equipped with an additional odour barrier, which
also closes the drain odour-tight, if the water seal in the odour trap has
evaporated. Odour nuisance is even avoided with drains that are only
seldom used. Odour barriers can be found in the catalogue.
