Tips For Success

  • Locating Hard to Find Leaks: Empty the area below the sink. Spread a sheet of newspaper flat over bottom of cabinet below sink and secure with tape. If water drips from a leaking area, it will leave a wet spot on the paper. Place stoppers in sink(s) and fill with water. Leave sink full for a while and then look for leaks. Remove stopper(s) and let the sink drain. Look for leaks. Turn on the water and disposal and allow them to run while looking again for leaks.
  • If leaks are not found, keep paper in place for a few days. If you see no indication of leaks, water may be from other sources. Check water filters, dish sprayer, faucet, dishwasher drain hose, sink/countertop seam, and countertop joints.
