Plumbing Issues? You’re Not Alone

Common plumbing problems in Twin Falls are more than just an occasional drip—they’re a regular headache for many homeowners. Whether it’s a leaky faucet that won’t quit or a water heater that barely makes it through winter, the mix of hard water, older homes, and extreme seasonal swings makes plumbing maintenance a big deal in this part of Idaho.

In fact, plumbing issues are among the top service calls TRW Plumbing gets each year in Twin Falls. Some problems are easy to fix if caught early, while others—like frozen pipes or persistent drain clogs—can lead to costly damage if ignored.

In this guide, we’ll walk through five of the most common problems we see in local homes, along with simple steps you can take to fix or prevent them before they turn into bigger issues.

1. Leaky Faucets That Just Won’t Quit

A leaky faucet might seem like a small annoyance, but for homeowners, it’s one of the most common—and costly—plumbing problems. That constant drip doesn’t just waste water; it can slowly add up on your utility bill and even stain your fixtures over time.

In many cases, the issue comes down to a worn-out washer or O-ring, which is especially common with Twin Falls’ hard water. Mineral buildup can damage the faucet’s internal parts, making a tight seal impossible.

How to fix a leaky faucet:

• DIY fix: Turn off the water supply under the sink, disassemble the faucet, and check the washer and cartridge. Replace worn parts and reassemble carefully.

Pro tip: If you notice more than one dripping faucet, it could be a sign of pressure issues or mineral damage in your home’s plumbing system.

2. Water Heater Woes: Hot Water Runs Out Fast

Water heater issues are more common than you might think—especially when you suddenly get hit with an icy shower halfway through your morning routine. If your hot water runs out too fast, or your heater is making rumbling or popping noises, it’s likely dealing with sediment buildup.

That’s a frequent issue in Twin Falls, where hard water leaves mineral deposits inside your water heater tank. Over time, this buildup reduces efficiency, shortens the unit’s lifespan, and makes your energy bills creep up.

How to fix it:

• Flush the tank: This removes sediment and can help restore efficiency. It’s recommended once or twice a year in hard water areas like ours.

• Adjust the thermostat: The ideal setting is around 120°F for comfort and safety.

Check with Idaho Power for possible energy rebates on high-efficiency water heaters. You may be eligible for incentives just for making your home more energy-smart.

3. Drains That Back Up or Smell Bad

Clogged drain solutions are something almost every homeowner needs at some point. Whether it’s your kitchen sink, shower, or laundry drain, a slow drain or bad odor usually means buildup is blocking the flow.

In Twin Falls homes, the usual culprits are:

• Grease and food particles in kitchen drains

• Hair and soap scum in bathroom sinks and tubs

• Tree roots sneaking into older sewer lines

How to fix it:

• Use a natural cleaner (like baking soda + vinegar) to break up minor clogs.

• Add a drain screen to catch hair and debris.

Tip: Avoid chemical drain cleaners—they can damage pipes and aren’t eco-friendly.

4. Water Pressure That’s Too Low or Keeps Changing

Low water pressure causes in Idaho homes are often tied to older plumbing systems, and Twin Falls is no exception. If your shower dribbles or your garden hose barely flows, it could signal a bigger issue.

Common causes:

• Mineral buildup (thanks to hard water common in our area)

• Corrosion in old galvanized pipes (common in homes built before the 1970s)

• Hidden leaks that waste water and lower pressure

How to fix it:

• Clean faucet aerators and showerheads to remove mineral deposits.

• Check if your pressure regulator valve is working properly.

Tip: Consistent low pressure may mean it’s time to consider a partial or full pipe replacement, especially in aging Twin Falls homes.

5. Frozen or Burst Pipes in the Winter

How to prevent frozen pipes is something every homeowner should know—especially with our frigid winters. Pipes in garages, crawlspaces, or along exterior walls are most at risk when temperatures drop below freezing.

Prevention tips:

• Insulate exposed pipes with foam sleeves or wrap.

• Let faucets drip slightly during hard freezes to keep water moving.

• Shut off and drain outdoor lines before winter hits.

If you suspect a frozen pipe:

• Turn off the main water supply.

• Gently warm the pipe using a hair dryer (never an open flame).

Tip: A little prep in the fall can save thousands in repair costs come winter.

Bonus Tip: Hard Water Is Behind Many Problems

Hard water plumbing problems in Twin Falls are more common than most homeowners realize. The mineral-rich water in our area leaves behind deposits that clog faucets, reduce water pressure, and shorten the lifespan of water heaters and appliances.

Solutions that work:

• Install a whole-home water softener to reduce mineral buildup.

• Add filters at key points (like kitchen sinks) for better water quality.

• Schedule annual maintenance to catch hard water damage early.

When to Call a Pro Instead of DIY

It’s tempting to tackle plumbing fixes on your own—but knowing when to call a plumber can save you stress, time, and costly damage.

DIY-friendly fixes:

• Replacing faucet washers or aerators

• Flushing a water heater (if you’re comfortable)

• Clearing minor clogs with a plunger or drain snake

When to call a plumber:

• Leaky faucets: If the faucet still drips after you’ve replaced parts, or the fixture is corroded or stuck.

• Water heater troubles: If your water heater is 8–10+ years old, leaking, or still not performing after basic maintenance.

• Persistent clogs or odors: If drains clog repeatedly, or strange smells come back even after clearing.

• Low water pressure: If water pressure changes throughout the house or suddenly drops.

• Frozen or burst pipes: If you have frozen or burst pipes, especially during winter.
