Cleaning a screen is is a lot easier than cleaning out your pipe. If grout has gotten stuck in the line, trying to clean it out yourself is probably not the best idea. You can attempt to break up some of the grout which works to help the line go a bit smoother. This is much easier if your pipes are plastic, rather than metal. It's up to a professional to fix this problem, though. When you grind things up in the garbage disposal, don't run the water while doing so. Although some say that running water will help keep the disposal running smoothly, this isn't always the case. This could actually make the garbage more sticky and cause more issues. Make it a habit to run your rarely used valves on a regular basis to avoid plumbing problems. Maintain them with penetrating oil, and turn them every so often to keep them from sticking. Government agencies can provide information about plumbing contractors. More information about Weehawken Licensed Plumbing.
