Why Your Water Bill Is Suddenly Higher and the Plumbing Causes Behind It

It is an unwelcome surprise for a homeowner in Rancho Cucamonga to open your water bill and see a number much higher than expected. Instead of a billing error, a sudden spike in your water bill is often one of the first signs of a hidden plumbing issue. Most of these problems can be resolved by a professional plumber.

The first step in dealing with a potentially high water bill and any plumbing causes is getting your usage and costs under control. This guide will take you through the most common issues, from simple fixes to complex hidden leaks. Our team at Peli Plumbing is here to help locate and repair a leak in your home.

Check for a Running Toilet First

A frequent cause for a high water bill is one of the easiest to overlook: a running toilet. A toilet that constantly runs, even silently, can waste a significant amount of water during a month. This issue is often caused by a faulty or worn-out component inside the toilet tank.

The problem is usually with either the flapper, which is the rubber seal at the bottom of the tank, or the fill valve. If the flapper doesn’t create a perfect seal, water will continuously leak from the tank into the bowl. The fill valve then works overtime to keep the tank full, creating a constant cycle of water waste. This can easily explain a higher running toilet water bill without any other obvious signs of a leak.

Hidden Leaks in Walls or Under Slabs

While a running toilet is a common issue, more serious leaks can hide from sight. Leaks within your walls or beneath your home’s foundation, known as slab leaks, are a less obvious cause of high water usage. These are particularly concerning for homeowners in the Inland Empire, as they can cause significant structural damage if not addressed.

Some hidden water leak signs include damp spots on walls or floors, the sound of running water when no fixtures are on, or unexplained warm areas on your floor. A slab leak water bill can be exceptionally high because the leak can persist for weeks or months before it’s discovered. Locating and fixing these issues requires professional equipment and expertise. If you notice any of these signs, it’s crucial to seek professional slab leak repair services immediately.

Dripping Faucets and Fixtures

A single dripping faucet can add a surprising amount to your water bill. That steady “drip, drip, drip” from a kitchen sink, showerhead, or bathroom faucet can waste gallons of water every day and even more over a month.

Many homeowners get accustomed to the sound of a small drip and delay a repair, not realizing its financial impact. The cause is often a worn-out washer or O-ring, which are simple components to replace.

Irrigation and Outdoor Leaks

Your plumbing system extends beyond the walls of your house. Leaks in your outdoor plumbing and irrigation systems are another common source of water waste. In Southern California, keeping our lawns and gardens green requires a lot of water, so a leak in the system can go undetected for a long time.

A crack in a sprinkler line underground can release a large volume of water whenever the system runs. A constantly dripping outdoor spigot or leaky hose connection can contribute to a higher bill. It’s a good practice to periodically walk your property while the sprinklers are on to check for unusual wet spots or geysers and to keep all outdoor faucets turned off tightly.

Water Heater Issues

Your water heater is another potential source of leaks that can increase your water bill. A failing water heater tank can develop slow leaks and not be immediately obvious. Sometimes, the leak is small enough that the water evaporates from the heat of the unit before it can pool on the floor.

The temperature and pressure (T&P) relief valve can also fail, allowing water to constantly drain from the tank. If you suspect a problem with your unit, it’s best to have it inspected. Our team offers professional water heater repair services to diagnose and resolve leaks or malfunctions.

How to Confirm a Leak Is Present

If you’re asking, “why is my water bill so high?” but cannot find an obvious source, you can perform a simple test using your water meter. This is a reliable way to confirm if there is a leak somewhere in your plumbing system.

• Turn off all water-using appliances
• Locate your water meter near the curb
• Look for a spinning leak indicator
• Note the meter reading and check again in two hours

When to Call Peli Plumbing

Once the water meter test confirms you have a leak, the next step is finding it. If you have checked for running toilets and dripping faucets without success, the leak is likely hidden. This is when it’s time to call a professional Rancho Cucamonga plumber.

Attempting to find a hidden leak on your own can cause damage to your home.
