I wanted to take a moment to personally say Thank You for introducing us to Drainbo® Natural Drain Cleaner. With an apartment complex of this size (almost 200 units) drain problems are numerous for us. Since installing the Drainbo® drums here at this property, it has significantly cut our maintenance calls for drain service. We also use it as a preventive measure in our vacant units. It is always a plus when we know we have someone we can truly count on!
