Column: Five warning signs you need to call a plumber

The drip of a faucet, the bang of pipes or the visible signs of a leak under the sink are obvious indicators of plumbing trouble. But other, potentially serious issues may not be as easy to spot. Homeowners should be on the lookout for these signs that it may be time to call a plumber.

Banging or clanking in the pipes, often referred to by plumbers as “water hammer,” occurs when a rush of water forces through a pipe and collides with a closed valve, creating a metallic noise. The sound indicates something inside the pipe is restricting water flow. Over time, that force can loosen joints as the water seeks an alternate path.

Pipe discoloration, especially rust, can signal a slow leak from a sink or drain line. Left unchecked, a small leak can grow into a costly problem. Sewer smells also should not be ignored. Pipes rely on traps and vents to keep odors from entering the home. A trap may have dried out or a vent line could be cracked, according to Family Handyman.

Low water pressure is another warning sign. Poor pressure may result from a clog, a hidden leak or pipes that are not properly sized for the home. Sluggish drains also indicate an issue. While homeowners can attempt to clear minor blockages, such as hair or debris, persistent drainage problems are best left to a professional.

Frequent shaking or rattling noises can mean pipes are not secured tightly enough. A plumber can tighten the mounting straps or replace them if necessary.

Plumbing issues should never be taken lightly. What begins as a small inconvenience can escalate quickly and cause thousands of dollars in damage if not addressed promptly.
