The answer to 'pipe repair slow draining' is that a slow-draining sink or tub is often caused by a clogged pipe or drain. Common causes include hair, soap scum, food debris, and other buildup in the pipes. Symptoms include water draining slowly, gurgling sounds, or water backing up in the sink or tub.
For minor clogs, you may be able to clear the pipe with a plunger, drain snake, or chemical drain cleaner. However, if the clog is deeper in the pipes or you cannot clear it, you'll likely need to call a professional plumber to use specialized tools and techniques to fully clean and unclog the pipes.
