If your pipes don’t drain as they should, it’s time to get the help of a professional drain cleaning service. Though it’s obvious when water drains slowly or sits in tubs and sinks, the reasons why are not. Anything from excess grease in the kitchen sink to lost hair in the bathroom drain can slowly build up over time, creating unmovable blockages that damage your plumbing. With Mr. Rooter’s HydroScrub technology, however, drains are easily cleared of clogs and kept in pristine condition for long-term use.
