Why Your Running Toilet Is Costing You More Than You Think

When we think of plumbing emergencies, most people imagine burst pipes or overflowing drains. But one of the most quietly expensive problems in Southern California homes is a running toilet. While it may seem like a minor nuisance, the cost of wasted water adds up fast—especially in a drought-prone region where every drop counts.

At 1st Choice Plumbing, Flood & Restoration, we’ve helped countless homeowners put a stop to this problem and restore efficiency to their bathrooms. Let’s take a closer look at what causes a toilet to run, why it matters, and when to call a professional at 866-437-0205.

What’s Actually Happening When a Toilet Keeps Running?

After you flush, water fills the tank until a float signals the valve to shut off. If something in that process fails, water continues to flow—either from the tank into the bowl or from the supply line into the tank.

Here are the most common culprits:

• Worn-out Flapper – The rubber flapper at the bottom of the tank may not be sealing properly, letting water leak into the bowl.
• Float Set Too High or Too Low – This affects when the valve shuts off. If it’s too high, the tank overfills; too low, and the flush may be weak.
• Faulty Fill Valve – The valve responsible for refilling the tank may be sticking open or failing to shut off completely.
• Cracks in the Overflow Tube – This part prevents the tank from overflowing, but if it’s cracked or misaligned, water may leak constantly.

These issues might seem small, but even a slow leak can waste 200 gallons a day or more—which can result in a surprisingly large spike on your water bill.

Why It’s More Than Just a Plumbing Problem

A running toilet is easy to ignore, especially when there’s no visible mess. But beyond the increased utility bills, here’s what’s really at stake:

• Environmental Impact – Southern California regularly faces drought conditions. Wasting water affects the whole community.
• Damage Over Time – Leaks can cause rust, corrosion, or warping in the tank and surrounding materials.
• Mold and Mildew Risk – Moist environments around the toilet base can breed hidden mold.
• Constant Noise – The never-ending sound of running water can be a major annoyance and stress trigger in your home.

DIY Fix or Time to Call a Pro?

You can sometimes fix a running toilet yourself by replacing a flapper or adjusting the float. But if you’ve done that and it’s still running—or if you’re not comfortable working inside the tank—don’t hesitate to call in expert help.

A plumber from 1st Choice Plumbing, Flood & Restoration can:

• Quickly diagnose the issue
• Replace worn or broken parts
• Ensure all connections are watertight
• Inspect for hidden leaks or signs of tank damage
• Recommend an efficient replacement if needed

Consider Upgrading for Long-Term Savings

If your toilet is more than 15 years old, it may be worth replacing it altogether. New models are more water-efficient and perform better, especially under California’s water use regulations. Low-flow toilets use as little as 1.28 gallons per flush—compared to older models that use up to 5 gallons.

At 1st Choice Plumbing, Flood & Restoration, we offer expert installation of modern, water-saving toilets and can help you select the right fit for your home. Not only will this lower your water bills, but it could also increase your home’s value and comfort.
