TLDR — Key Takeaways

  • Using chemical drain cleaners damages pipes over time
  • Over-tightening connections causes cracks and leaks
  • Ignoring small leaks leads to major water damage
  • DIY gas line work is dangerous and illegal without a license
  • Not knowing where the main shut-off valve is can cost thousands

At Pro Plumbing Las Vegas, we see the same mistakes repeatedly from well-intentioned Las Vegas homeowners trying to save money on plumbing. Here are the top 10 mistakes — and what to do instead.

1. Using Chemical Drain Cleaners

Chemical drain cleaners like Drano and Liquid-Plumr are harsh acids that can damage pipe joints, corrode metal pipes, and create dangerous fumes. They also rarely solve the underlying problem. Use a plunger for minor clogs, and call us for stubborn ones.

2. Over-Tightening Connections

"Hand tight plus a quarter turn" is the rule for most plumbing connections. Over-tightening cracks fittings and strips threads, causing leaks. This is especially common with toilet supply lines and faucet connections.

3. Ignoring Small Leaks

A small drip under the sink or a slow toilet leak seems minor but can cause significant water damage and mold growth over time. Fix small leaks immediately — they never get better on their own.

4. DIY Gas Line Work

Gas line work requires a licensed plumber in Nevada. DIY gas line repairs are dangerous, illegal, and can void your homeowners insurance. Always call a licensed professional for any gas line work.

5. Not Knowing Where the Main Shut-Off Is

Every adult in your household should know where the main water shut-off valve is located. In an emergency, every minute counts. Most Las Vegas homes have the shut-off in the garage or near the water meter.

6. Flushing "Flushable" Wipes

Despite the label, "flushable" wipes don't break down in sewer systems. They're a leading cause of sewer line clogs and backups. Dispose of all wipes in the trash.

7. Ignoring Hard Water

Many Las Vegas homeowners accept hard water as a fact of life without realizing how much damage it's causing. A water softener is one of the best investments you can make in your home's plumbing system.
