Most Common Bathroom Plumbing Problems

1. Dripping Faucets

The Problem:

A dripping faucet might seem minor, but it can waste hundreds of gallons of water per year, increasing your water bill unnecessarily. The most common bathroom plumbing causes include:

  • Worn-out washers or O-rings
  • Corroded valve seats
  • Improper faucet installation

The Solution:

While a temporary fix might stop the drip temporarily, a long-term repair or replacement is often needed. At Leak Experts USA, we:

✔ Inspect the faucet’s internal components

✔ Replace damaged washers, cartridges, or stems

✔ Install new high-efficiency faucets if necessary

Pro Tip: If you have older bathroom plumbing, consider a whole-home repiping service to prevent recurring leaks.

2. Clogged Drains

The Problem:

Clogged bathroom drains are a nuisance, often caused by:

8. Grout & Sealant Deterioration

The Problem:

Cracked grout lets water seep into walls, causing mold and rot.

The Solution:

We repair sealant and offer water damage restoration if needed.

9. Slow-Draining Sink or Tub

The Problem:

Slow drainage is one of the most common bathroom plumbing complaints in Southern Highlands and Las Vegas homes. The issue typically stems from:

  • Hair clogs – The #1 culprit, especially in showers and tubs. Hair binds with soap scum, creating stubborn blockages.
  • Soap & shampoo buildup – Over time, soap residue hardens inside pipes, narrowing the passageway for water.

Signs You Have a Drainage Problem:

🚿 Water pools around your feet in the shower

⏳ Sink takes minutes to drain fully

💦 Gurgling sounds from the drain

🤢 Unpleasant odors coming from pipes

The Solution:

While store-bought drain cleaners might offer a temporary fix, they often damage pipes with harsh chemicals. Leak Experts USA provides professional, long-lasting solutions:

✔ Drain Snaking – We use motorized augers to break up and remove deep clogs.

✔ Hydro Jetting – High-pressure water blasting clears even the toughest buildup without harming pipes.

Pro Tip: Install drain strainers to catch hair and debris before they enter your pipes!

10. Broken Shower Valves

The Problem:

A malfunctioning shower valve can turn a relaxing shower into an unpleasant experience. Common symptoms include:

  • Temperature fluctuations – Sudden bursts of scalding hot or freezing cold water.
  • Leaking handles – Drips when the shower is turned off.
  • Difficulty adjusting water flow – Stiff or loose handles that don’t respond properly.
  • Low water pressure – Weak flow even when fully turned on.

Causes of Shower Valve Failure:

  • Worn-out cartridges – The internal mechanism that controls water flow and temperature degrades over time.
  • Mineral buildup – Hard water deposits corrode valve components.
  • Faulty installation – Poorly fitted valves lead to leaks and inconsistent performance.

The Solution:

Ignoring a faulty shower valve can lead to water waste, higher bills, and even water damage. Leak Experts USA provides:

Valve Replacement – We install high-quality, durable shower valves for smooth operation.

Cartridge Repair – If only the internal parts are damaged, we replace them without full valve removal.

Did You Know? Modern shower valves come with anti-scald technology, making them safer for families!
