If you own a home or business in Las Vegas, you’ve probably dealt with at least one plumbing headache. Our desert city presents a unique set of challenges — from the notoriously hard water sourced from Lake Mead, to scorching summer heat and occasional winter cold snaps. Understanding the most common plumbing issues in the Las Vegas Valley is your first line of defense against expensive repairs.
At MG Drain Services LLC, we’ve been solving plumbing problems across Las Vegas, Henderson, North Las Vegas, and Summerlin since 2015. With over 25 years of combined experience, BBB accreditation, and bilingual English/Spanish service, our family-owned team has seen it all. Here are the plumbing issues we respond to most often — and exactly what you can do about them.
1. Hard Water Damage — Las Vegas’s #1 Plumbing Problem
Las Vegas consistently ranks as one of the cities with the hardest water in the United States. The culprit is the high concentration of calcium and magnesium minerals found in our water, sourced primarily from Lake Mead and the Colorado River.
These minerals leave behind a white, chalky buildup — called scale — inside your pipes, fixtures, appliances, and water heater. Over time, scale narrows your pipes, reduces water flow, degrades seals and O-rings in faucets, and forces appliances like water heaters and dishwashers to work harder. The result: higher energy bills, frequent repairs, and a dramatically shorter appliance lifespan.
Hard water affects virtually every part of your plumbing system, which is why it underlies so many of the other issues on this list.
💡 Pro Tip: Installing a whole-home water softener is the single best investment a Las Vegas homeowner can make to protect their entire plumbing system long-term. It pays for itself by extending the life of your pipes, appliances, and fixtures.
2. Clogged and Slow Drains
Slow and clogged drains are among the most common service calls we receive. In Las Vegas homes, the usual suspects are a combination of hair, soap scum, grease — and hard water mineral buildup that gradually narrows drain pipes over time.
Kitchen drains are particularly prone to grease clogs, especially when cooking oil is poured down the sink. In bathrooms, hair and soap residue create a sticky barrier that traps everything flowing by. Left untreated, slow drains become fully blocked drains, leading to backups and potential water damage to your home.
Our professional drain cleaning and hydro jetting services cut through even the most stubborn blockages and leave pipes clean from wall to wall — not just a small hole punched through the clog.
💡 Pro Tip: Never pour cooking grease down the drain. Let it cool and solidify in a container, then dispose of it in the trash. For kitchen sinks, run hot water for 30 seconds after each use to keep grease moving through the line.
3. Water Heater Failures
Water heaters in Las Vegas have a tough life. The high mineral content in our local water supply causes sediment to accumulate rapidly at the bottom of tank-style water heaters. This layer of sediment acts as an insulator, forcing the heating element to work harder and longer to heat the water above it.
The symptoms are hard to miss: skyrocketing energy bills, inconsistent hot water, strange popping or rumbling noises from the unit, and eventually — premature failure. The national average lifespan for a water heater is 8–12 years. In Las Vegas, without proper maintenance, many units fail well before that mark.
💡 Pro Tip: Flush your water heater tank at least once per year to remove sediment buildup. This simple maintenance step can add years to your unit’s life. If you hear rumbling or popping from your water heater, it’s a sign sediment has already built up significantly — call a plumber.
4. Sewer Line Blockages
Sewer line blockages are a serious issue that affect both older and newer Las Vegas homes. The main culprits include tree root intrusion, accumulated grease and debris, and deteriorating pipes in older parts of the valley.
Tree roots naturally seek out moisture — and even in the desert, landscaping irrigation provides enough water to attract root growth toward your sewer lines. Older neighborhoods often have aging clay or cast iron pipes that are more susceptible to cracking and root intrusion. A blocked sewer line can cause multiple drains in your home to back up simultaneously, and in severe cases, raw sewage can back up into your home — a health hazard requiring immediate attention.
Our sewer camera inspection service allows us to pinpoint exactly where the problem is, without unnecessary digging or guesswork.
💡 Pro Tip: If multiple drains in your home are slow or backing up at the same time, that’s a red flag pointing to the sewer line — not individual drain clogs. Don’t wait: call a professional immediately. A camera inspection can save you thousands in avoidable damage.
5. Leaky Faucets and Fixtures
A dripping faucet might seem like a minor annoyance, but in water-scarce Las Vegas, every drop counts. A faucet dripping just once per second wastes over 3,000 gallons of water per year — and that’s money going straight down the drain on your water bill.
In Las Vegas, hard water accelerates wear on internal faucet components like washers, O-rings, cartridges, and valve seats. Mineral deposits also build up around fixtures over time, making them stiff to operate and harder to seal properly. The result is more frequent repairs compared to cities with soft water.
💡 Pro Tip: If you notice white or orange mineral deposits building up around your faucets and fixtures, that’s hard water attacking your plumbing. Addressing it early with a water softener prevents more costly fixture replacements down the road.
6. Running Toilets
A constantly running toilet is one of the most water-wasteful problems in any household. A toilet that won’t stop running can waste 200 gallons or more per day — a significant issue in a desert city where water conservation matters and water bills are no joke.
The most common cause is a worn or warped flapper valve that no longer creates a proper seal, allowing water to flow continuously from the tank into the bowl. In Las Vegas, hard water deposits on the flapper, fill valve, and overflow tube accelerate wear on these components, causing them to fail faster than in softer-water markets. You’ll often hear a hissing or trickling sound if your toilet is running.
💡 Pro Tip: Try the food coloring test — drop a few drops into the toilet tank. If color appears in the bowl without flushing, your flapper needs replacing. It’s an inexpensive fix that can save hundreds of dollars a year on your SNWA water bill.
7. Low Water Pressure
Low water pressure makes everything from showering to washing dishes a chore. In Las Vegas, the most common cause isn’t a problem with the city’s supply — it’s scale buildup inside your own pipes and fixtures.
As mineral deposits accumulate inside pipes over the years, the effective diameter of the pipe narrows, restricting water flow. Showerheads and faucet aerators are especially prone to clogging with calcium deposits. In some cases, low pressure can also signal a hidden leak somewhere in your supply lines — so it’s worth having a professional take a look if the problem is widespread.
💡 Pro Tip: Start by unscrewing your showerhead and soaking it in white vinegar overnight. This dissolves mineral deposits and often restores full water pressure without a service call. If multiple fixtures have low pressure, the problem is deeper in your pipes.
8. Garbage Disposal Issues
Garbage disposals are standard in most Las Vegas kitchens, but they’re also one of the most commonly misused appliances in the home. Jamming and clogging are by far the most frequent disposal issues we encounter.
Hard items like bones and fruit pits should never go down the disposal. Neither should fibrous materials like celery, artichoke leaves, or onion skins — these wrap around the blades and jam the motor. Grease and starchy foods like pasta and rice build up and cause blockages deeper in the drain line. Hard water compounds the problem by leaving scale deposits on internal components over time.
💡 Pro Tip: Always run cold water before, during, and for 30 seconds after using your garbage disposal. Cold water keeps fats solid so they’re chopped and flushed through the line rather than coating your pipes in grease.
9. Pipe Corrosion and Pinhole Leaks
Pinhole leaks in copper pipes are a well-documented and widespread problem in the Las Vegas Valley. The unique chemistry of Las Vegas water — particularly its high pH and mineral content — accelerates a process called pitting corrosion in copper pipes.
This type of corrosion creates tiny, pinhole-sized perforations in the pipe wall. While the leaks start small, they can cause significant water damage inside walls, ceilings, and floors long before they’re detected. Homes built between the 1970s and early 2000s with original copper plumbing are most at risk, but the problem can affect newer homes too.
💡 Pro Tip: Unexplained water stains on walls or ceilings, musty odors, or a sudden unexplained spike in your water bill are all warning signs of a hidden pipe leak. Don’t wait — call for a professional leak detection inspection right away. The longer a leak goes undetected, the more damage it causes.
10. Outdoor Plumbing and Irrigation Issues
Las Vegas’s extreme heat and occasional winter cold snaps create unique challenges for outdoor plumbing. While full pipe freezes are rare, temperatures do occasionally dip below freezing, which can crack exposed outdoor hose bibs and irrigation fittings.
More commonly, the intense UV radiation and summer heat degrade plastic irrigation fittings and drip system components faster than in milder climates. Sprinkler heads clog with mineral deposits, and irrigation lines develop cracks that waste water and create muddy patches in the yard. With Southern Nevada Water Authority (SNWA) water restrictions in effect, an undetected irrigation leak can also result in fines.
💡 Pro Tip: Inspect your irrigation system at the start of each watering season. Look for broken sprinkler heads, soggy patches in the yard, and visible cracks in fittings. Catching leaks early saves water, avoids SNWA penalty fees, and keeps your landscaping healthy.
