Drain Odor Elimination In Multifamily Buildings
In a 300-unit building, dozens of drains feed each riser. When biofilm builds inside the riser, the smell escapes through every dry trap on every floor — and tenants in unit 1207 blame their own sink.
Treat at the riser, not the unit
A monthly foaming treatment dropped into the riser from the rooftop access covers the entire stack and is far cheaper than 300 individual unit visits.
Educate residents on dry traps
Guest bathrooms and unused floor drains evaporate within weeks. A reminder card in lease packets to run water monthly prevents most complaints.
