Toilet leaks can get expensive fast! 

Toilets are the most common place to find water leaks. A toilet leak can consume as much as 5,000 gallons per day! Based on more than two-decades of providing water assessments for multifamily water customers, large multifamily property will often have 25% of their toilets leaking.  One local multifamily property we recently worked with reduced water use by 12,500 gallons per day by repairing malfunctioning toilets. These simple repairs saved them about $9,000 per month in sewer and water utility charges! Toilet leaks are frustrating because it’s hard to catch them in action. 

Common toilet problems 

  • Tank water level is too high: It should be about ½ inch below the overfill pipe.  

  • Flapper leaks: Flappers are typically guaranteed for only five years and should be replaced on a regular schedule. Check for toilet leaks every 6 to 12 months.
