The most common problems the new SAWS ConnectH2O meters detect are toilet leaks. And they can use a shocking amount of water when they run amok.
It’s a good idea to check your toilets for leaks, especially during the winter average period from mid- November to mid-March. (That’s when your sewer service charges are calculated for next year based on your average winter water use.)
To test for leaks, put a few drops of food coloring in the toilet tank and don’t flush. Wait 15 minutes. If you see color in the bowl, the tank has a leak — most likely from a worn or dirty flapper valve. Before you call a plumber, check to see if mineral deposits are to blame. An inexpensive rinse with a jug of vinegar can clear it up.
Also, avoid using cleaning tablets in the toilet tank. They can eat away at internal parts, causing even worse leaks and pricey plumbing repairs.
