Don’t Let Plumbing Issues Be Ignored

Small plumbing issues may not seem like much, but if not addressed ASAP, those little things you’ve learned to live with can evolve into major problems that disrupt your daily routine. Watch out for the early warning signs of a plumbing issue and know what plumbing services team to call to get your plumbing system back under control.

Call our plumbing services team if you notice:

An unexplained increase in your water bills: A sudden spike in your water bills could indicate a hidden leak or inefficient plumbing fixtures.
Persistently dripping faucets or running toilets: These seemingly minor problems can waste significant amounts of water over time and may indicate deeper issues.
Slow-draining sinks, showers, or tubs: Slow drains can suggest clogged pipes or issues further within your plumbing system.
Frequent backups or blockages: Frequent drain backups might signal a serious issue, such as tree root intrusion in your sewer line.
Foul odors: Persistent unpleasant smells can indicate blocked or damaged pipes or sewer lines.
Visible water stains or damage: Brown spots on ceilings or walls, or warped flooring can be a sign of a hidden leak.
Reduced water pressure: Sudden low water pressure throughout your home could indicate a broken water line or a problem with your water heater.

Catching these issues early can save you from costly repairs down the line. Don’t let plumbing problems persist; get in touch with the Armstrong Plumbing services team at the first sign of trouble. We’re here to ensure your home’s plumbing system runs smoothly and efficiently.
