What causes buildup?
Bathing, laundry and dishwashing all cause buildup. Using a garbage disposal especially contributes to buildup. If you participate in any of these activities (as we all do every day), chances are you have buildup happening right now in your drains and pipes. Buildup will slow the water flow and eventually block the line, causing backup and requiring servicing. It will also be a breeding ground for odors and disease-causing germs.

Also, if a sink has not been used for a while the p-trap can become dry because of evaporation allowing odors to get back up the drain. Running water down sinks periodically keeps the P-trap and water barrier full.
