Toilet and Faucet Leaks in Toledo: Find Them, Fix Them, Check Your Meter

Page date: November 15, 2026.

Small leaks are easy to ignore because they rarely cause a crisis. They do show up on the water bill, and some of them, like a leak under a floor or behind a wall, cause rot and mold before anyone notices. This guide covers how to find leaks, which ones are simple homeowner fixes, how Toledo's water meters can help, and when a permit comes into play.

How much water small leaks waste

National figures from the U.S. Environmental Protection Agency's WaterSense program give a sense of scale:

The average household's leaks can account for more than 9,300 gallons of water wasted every year, and nine percent of homes have leaks that waste 50 gallons or more per day. (EPA, Fix a Leak Week)
Common household leaks are worn toilet flappers, dripping faucets and other leaking valves, and fixing easily corrected leaks can save homeowners about 10 percent on water bills. (EPA, Fix a Leak Week)
Household leaks waste nearly 900 billion gallons of water a year nationwide. (EPA WaterSense, Statistics and Facts)

These are national numbers. No Toledo-specific leak statistics were found.

Step 1: Check the meter

The meter test catches leaks you cannot see. EPA's version: check your water meter before and after a two-hour period when no water is being used; if the reading changes at all, you probably have a leak. (EPA, Fix a Leak Week)

Toledo's smart meters. The City of Toledo has been installing smart meters as part of an Advanced Metering Infrastructure (AMI) system. The City says the replacement is mandatory, that meters must comply with Department of Public Utilities specifications under Toledo Municipal Code Chapter 937, and that after installation your usage is still "measured and available from the meter visually" while the meter is being activated. The City also flags meters for conditions including "Flow Concern," which "indicates that the flow of water is either extremely high or extremely low." If the City sees a problem with your meter, a customer service representative will call the phone number on file. (City of Toledo, Meters)

For questions about your meter or bill, the Department of Public Utilities customer service line is 419-245-1800, Monday through Friday, 7 a.m. to 5:30 p.m. (City of Toledo, DPU Customer Service)

A winter bill check. EPA suggests looking at water use during a colder month such as January or February; if a family of four uses more than 12,000 gallons per month, there could be serious leaks. (EPA, Fix a Leak Week)

Step 2: Toilets

Toilets are the most common silent leak.

Dye test. EPA recommends putting a few drops of food coloring in the toilet tank; if color appears in the bowl within 10 minutes without flushing, the toilet is leaking. Flush right after the test to avoid staining. (EPA, Fix a Leak Week)

Common causes and fixes:

Worn flapper. The rubber seal at the bottom of the tank hardens or warps. Replacing it is usually a simple, inexpensive homeowner job. Take the old one to the store to match it.
Fill valve set too high. If water trickles into the overflow tube, lower the float or adjust the fill valve so the water stops about an inch below the top of the tube.
Chain problems. A chain that is too short holds the flapper open; too long and it can get trapped under it.
Running intermittently ("phantom flush"). The tank slowly leaks into the bowl and refills every so often. This is almost always the flapper or flush valve seat.

Leaks at the base. Water on the floor around the toilet can come from a failed wax ring, a cracked bowl or tank, condensation in humid weather, or a leaking supply line. A failed wax ring needs the toilet pulled and reset. A cracked porcelain bowl or tank needs replacement.

Supply lines. Braided supply lines and the small shut-off valve behind the toilet wear out. Replacing an old line is cheap insurance against a burst under pressure.

Step 3: Faucets and showers

Dripping spout: worn cartridges, washers or seats depending on faucet type. Identify the brand and model if you can; replacement cartridges are model-specific.
Leak around the handle or base: worn O-rings or packing.
Leaking under the sink: check supply line connections, the faucet's own connections and the drain trap. Put a dry paper towel under each joint to find which one drips.
Showerheads: a drip from the head after the valve is off usually means a worn valve cartridge. A leak at the arm connection usually needs new thread tape.

Before taking anything apart, close the shut-off valves under the sink and open the faucet to relieve pressure. Put a towel in the sink so small parts do not go down the drain.

Step 4: Outside and hidden leaks

Hose bibs. Check outdoor faucets in spring for leaks or splits caused by freezing. The City of Toledo advises turning off water to garden hose connections at an inside valve and draining the exposed piping before freezing weather. (City of Toledo, How to Prevent Frozen Pipes)
Irrigation systems. EPA notes that an irrigation leak about the thickness of a dime can waste about 6,300 gallons per month, and recommends checking systems each spring for frost or freeze damage. (EPA, Fix a Leak Week)
Signs of hidden leaks: stains on ceilings below bathrooms, soft or discolored flooring, musty odors, peeling paint, or a meter that keeps moving with everything off.
Service line. A wet spot in the yard between the meter and the street, or a sudden rise in use without any change in habits, can mean a leak in the service line. The City owns the service line on the city side of the property line, and the property owner owns the customer side. (City of Toledo, Lead Line Replacements) Report leaks in the street or tree lawn to Engage Toledo at 419-936-2020. (City of Toledo, DPU Customer Service)

Renters

Toledo's Housing Code requires owners and lessors to keep flush toilets connected to a water system that provides "an adequate amount of running water under pressure" and to keep lavatories, tubs or showers and kitchen sinks "in good working condition." Tenants, for their part, must properly use and operate plumbing fixtures. (TMC 1745.07) If you rent, report leaks to your landlord in writing.

When a repair needs a permit

Replacing a flapper, cartridge or supply line is maintenance. Replacing or adding fixtures, or changing piping, is plumbing work. The City says permits are required for plumbing work other than minor violation corrections, and Toledo's fee schedule applies plumbing permit fees to fixtures "new or replacement." (City of Toledo, When are permits required; TMC 1307.05) If you are unsure, ask the Division of Building Inspection at 419-245-1220. (City of Toledo, Building Inspection)

Getting help with the bill

The City of Toledo lists a water bill assistance program for eligible residents with past-due water, sewer and stormwater balances. (City of Toledo, Homeowners' Resources)
