How to Fix Common Plumbing Issues at Home

Plumbing issues are an inevitable part of home ownership. While some might seem like daunting mysteries, many can be solved without calling a plumber. This guide provides a hands-on approach to fixing frequent plumbing problems. If things go awry, don’t hesitate to call a pro. Your pipes—and peace of mind—are worth it.

Leaky or Drippy Faucet

Problem: A leaky faucet wastes water and can drive anyone crazy with its drip…drip…drip. It’s also a money drain, as even a small drip can waste gallons of water over time.

Solution: First, identify the type of faucet you have—compression, ball-type, cartridge, or ceramic disk. Compression faucets, the most common, have a washer that often wears out. Shut off the water supply under the sink, then take apart the faucet and inspect the washer. If worn, replace it. For other faucet types, check O-rings and seals, which may also need replacement. Reassemble the faucet, turn the water back on, and give it a test.

Low Water Pressure

Problem: Low water pressure is a common frustration, often caused by buildup in pipes, a blocked aerator, or a hidden leak.

Solution: Begin by unscrewing the faucet aerator (the screen at the end of the faucet). Rinse off any debris or mineral buildup, then reattach it. If cleaning the aerator doesn’t work, check for leaks around faucets, the water heater, or visible pipes. Tighten any loose connections, but if the issue persists, you may have a more significant blockage, which is when you may want to call in a plumber.

Clogged Drains or Slow-Draining Sink or Tub

Problem: Clogs happen when hair, soap scum, or food debris build up over time, slowing water flow.

Solution: A sink plunger is a great first attempt. Place the plunger over the drain, push down to create suction, and pull up sharply. For a stubborn clog, a drain snake can be fed down to break up the blockage. Try pouring a solution of baking soda and vinegar down the drain, followed by boiling water, to clear minor clogs. Avoid using chemical drain cleaners regularly, as they can corrode pipes.

Running Toilet

Problem: A running toilet keeps water flowing into the tank and bowl, wasting water and money.

Solution: Lift the tank lid and look inside; you’ll usually find a faulty flapper, fill valve, or flush valve. Inspect the flapper to see if it’s not sealing properly, which can cause continuous running. If worn or warped, replace it. Next, check the chain length to ensure it’s not too tight, as it may be preventing the flapper from sealing. If adjusting these parts doesn’t fix it, the fill valve might need replacement.

Backed-Up Toilet That Won’t Drain

Problem: A toilet that backs up and refuses to drain is an unpleasant situation.

Solution: First, try using a toilet plunger. For tougher clogs, a toilet auger (also called a closet auger) may reach the clog deeper in the pipe. Insert it, crank the handle to break up the clog, and flush. For non-flushable items, like toys or excess paper, avoid flushing to prevent overflow. Call a professional if the auger fails, as the clog could be in the main sewer line.

Banging Pipes

Problem: Loud banging pipes, also known as “water hammer,” occur when water flow suddenly stops, causing a shockwave that rattles the pipes.

Solution: First, ensure pipes are securely attached to joists. Adding pipe insulation can reduce the noise. Another fix is to install a water hammer arrestor—a small device that absorbs the shock. If water pressure is too high, adjust it at the water main, but only if you’re familiar with this setup. If unsure, consult a plumber, as excessively high water pressure can harm your plumbing system.

Water Heater Problems

Problem: Cold showers or inconsistent water temperature can be caused by sediment buildup, a faulty thermostat, or a broken heating element.

Solution: Drain the water heater tank at least once a year to flush out sediment. This helps improve efficiency and extends the life of the heater. For electric heaters, replace the heating element if broken. If your heater has a gas burner, check for a steady blue flame. A yellow or flickering flame might indicate the need for burner cleaning or a professional tune-up.

Commonly Asked Questions About Home Plumbing

What tools should every homeowner have for plumbing repairs?
A wrench set, pliers, a toilet plunger, sink plunger, plumber’s tape, a drain snake, and an auger are good basics.

How can I prevent pipes from freezing in winter?
Wrap exposed pipes with insulation, keep the thermostat steady, and open cabinet doors to let warm air reach pipes under sinks.

Why does my drain smell bad?
A smelly drain usually means a buildup of debris or gunk. Cleaning it with baking soda, vinegar, and hot water often helps.

How often should I flush my water heater?
Flushing your water heater once a year is ideal for removing sediment.

When should I call a plumber?
If you can’t locate a leak, the clog is persistent, or you’re unsure about handling high-risk fixes, it’s best to call in a professional.

Additional Tips for Plumbing DIYers

• Know where your main shut-off valve is and learn how to turn off your home’s water supply in emergencies.
• Avoid chemical drain cleaners as a go-to. These can erode pipes and cause more damage over time.
• Monitor your water bill. Sudden increases could point to hidden leaks that need immediate attention.
• Use strainers in drains to prevent clogs, especially in the kitchen and bathroom.
• Test your water pressure regularly. It should range between 40-60 psi for residential homes.

Leaky faucets, low water pressure, clogs, running toilets, banging pipes, and water heater issues all have DIY solutions that are straightforward with the right approach. However, when plumbing problems get complicated or involve safety risks, calling a plumber is the best choice.
