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. 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 sinks full for a while. Look for leaks. Remove stopper(s) and let sink drain. Look for leaks. Turn on the water and disposal and allow them to run while looking 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, dishwater drain hose, sink/countertop seam, countertop joints.
