The Most Common Plumbing Issues & Mistakes You Should Avoid
By Thomas Terry, SameDay Heating & Air
Plumbing problems always seem to happen at the worst times. A leaky pipe, a clogged drain, or a running toilet can quickly become a major hassle if not handled properly. Fortunately, you can avoid plumbing issues with the right knowledge and maintenance.
Below, we’ll walk you through the most common plumbing problems, mistakes homeowners make, and simple ways to prevent costly repairs. It doesn’t matter if it’s a dripping faucet, a clogged drain, or flushing things that shouldn’t go down the toilet. Knowing what to look for saves you time, money, and frustration.
Understanding Common Plumbing Issues
Plumbing problems are an expected part of homeownership. However, knowing the most common issues lets you catch them early and avoid nasty surprises. Here are some of the top plumbing problems homeowners face and what might be causing them.
Dripping Faucets and Faulty Faucets
A dripping faucet may not seem like a big deal. Over time, however, it can waste gallons of water and increase your utility bill. Worn-out washers, O-rings, or even corrosion inside the faucet are common culprits. Fixing a leaky faucet early can prevent bigger plumbing problems down the road.
Running Toilets
A constantly running toilet can waste hundreds of gallons of water daily. A faulty flapper, an issue with the fill valve, or a problem with the chain inside the tank, often causes this issue. A quick inspection and replacement of worn-out parts usually solves the problem.
Clogged Toilets
Toilets become clogged when too much toilet paper is used, or improper items are flushed. Plungers often work for minor clogs, but persistent blockages may require professional drain cleaning to prevent bigger plumbing issues.
Slow or Clogged Drains
Hair, soap scum, food scraps, and grease buildup slow down or completely block your drains. Chemical drain cleaners might offer a temporary fix. However, they can damage pipes over time. Professional drain cleaning is the best way to remove stubborn clogs safely.
Water Heater Issues
If your water isn’t hot enough, you may have a problem with your water heater. Common issues include sediment buildup, a faulty thermostat, or a broken heating element. Regular maintenance, like flushing the tank annually, extends the life of your water heater.
Leaky Pipes and Main Water Line Leaks
Leaks can occur anywhere in your plumbing system. You might experience anything from small drips under the sink to major main water line issues. Even minor leaks cause mold growth, water damage, and higher water bills. If you notice water stains, musty smells, or damp areas, it’s important to get a professional inspection.
Low Water Pressure
Weak water pressure frustrates daily tasks like showering and washing dishes. This issue is often caused by pipe corrosion, sediment buildup, or leaks in the plumbing system. Cleaning faucet aerators or calling a plumber to inspect for hidden leaks restores normal water flow.
Common Plumbing Mistakes to Avoid
Even with the best intentions, homeowners often make plumbing mistakes, leading to bigger problems. Avoiding these common errors keeps your plumbing system running at its best.
Flushing Improper Items Down the Toilet
The only things that should go down the toilet are human waste and toilet paper. Flushing wipes, feminine hygiene products, cotton swabs, or paper towels can cause serious clogs. Teaching household members, especially kids, what not to flush prevents backups.
Ignoring Small Leaks and Routine Maintenance
A small leak might not seem urgent, but if left unattended, it can cause water damage, mold growth, and higher water bills. Check under sinks, around toilets, and behind appliances for leaks.
DIY Repairs Beyond Skill Level
Fixing a minor plumbing issue yourself can be tempting. However, tackling complex repairs without the right knowledge causes more harm than good. Overtightening fittings, using the wrong tools, or incorrectly installing parts can lead to leaks or broken pipes. If you’re unsure, it’s always best to call a professional plumber.
Tips for Preventing Plumbing Problems
Preventative maintenance is key to keeping your plumbing system in top shape. By following a few simple steps, you can avoid many common plumbing issues and costly repairs.
Schedule Regular Inspections
A professional plumber can identify small problems that might cause you headaches. Regular inspections detect leaks, corrosion, and potential clogs. Annual check-ups are a great way to keep everything running well.
Winterize Your Plumbing
Cold weather causes pipes to freeze and burst, leading to serious water damage. Insulate exposed pipes to protect your plumbing during winter. It’s also important to keep cabinets open to allow warm air to circulate and to let faucets drip slightly during extreme cold to prevent freezing.
Proper Fixture Usage
Being mindful of how you use your plumbing fixtures extends their lifespan. Avoid overloading garbage disposals, don’t hang heavy items on showerheads, and use strainers in sinks to prevent debris from clogging drains. Small habits like these make a big difference in preventing plumbing issues.
When to Call a Professional: Plumbing Emergencies & More
Some plumbing maintenance can be handled on your own. However, there are times when calling a professional is the best choice. Knowing when to seek assistance prevents small issues from becoming major and expensive disasters.
Major Leaks or Burst Pipes
If you notice water pooling under sinks, behind walls, or on the floor, you may have a serious leak. Burst pipes cause extensive water damage in a short amount of time. Shut off your main water supply and call a plumber immediately to prevent further damage.
Persistent Clogs or Slow Drains
If plungers and drain cleaners aren’t solving your clog, it’s time to call a professional. Recurring clogs indicate a deeper blockage in your plumbing system, and chemical drain cleaners weaken pipes over time. A professional drain cleaning service can safely remove tough clogs.
No Hot Water or Water Heater Issues
Your water heater may need repairs if it isn’t producing hot water or is making small noises. Sediment buildup, a faulty heating element, or even a failing unit could be the cause. A plumber can diagnose the issue and recommend the best course of action.
Sewage Backup or Bad Odors
Foul smells from drains or standing sewage in your home are signs of a serious plumbing problem. These issues may indicate a blockage in the main sewer line. This requires immediate attention from a professional plumber.
Low Water Pressure Throughout the House
A bigger issue could be if you notice weak water pressure in multiple faucets. This could be a leak in the main water line or pipe sediment buildup. A plumber can assess the situation and restore proper water flow.
