Signs You Need Professional Drain Cleaning
A drain that has slowed gradually over weeks, one that gurgles when another fixture runs, standing water that takes a long time to clear, or a clog that comes back shortly after you have tried to clear it yourself are all signs it is time for professional cleaning rather than another bottle of store-bought cleaner. Persistent odor near a drain is another sign, since it often means buildup or a blockage further down the line than a homeowner can reach.
