Overflow or leak: stop the water first
An overflowing toilet is an urgent problem. Lift the tank lid and push the flapper down to stop refilling, then close the shutoff valve at the wall. That stops the tank from sending more water to the bowl. If water keeps rising when you flush, the clog is below the toilet.
We handle emergency toilet calls 24/7 and book same-day visits when available. A toilet that leaks at the base is also urgent, because the water sits under the floor covering and can rot the subfloor.
Overflowing bowl
Usually a clog in the toilet trap or the drain behind it. If other fixtures gurgle too, the clog is in the main line. See drain cleaning.
Leak at the base
A failed wax ring or loose closet bolts let water escape at the floor. A wobbly toilet often leaks.
Running or hissing
A flapper that does not seal or a fill valve that does not shut off wastes water all day and shows up on the bill.
Weak flush
Clogged rim jets, a low water level in the tank or a partial blockage reduce flushing power.
Running toilets and high bills
A running toilet is one of the most common reasons for a jump in the water bill. A worn flapper can leak gallons a day with no sound. Put a few drops of food coloring in the tank and wait fifteen minutes without flushing. If color shows in the bowl, the flapper is leaking.
The cure is usually a flapper or fill valve replacement, a short job. For leaks elsewhere in the house, see leak detection.
What a toilet repair involves
| Problem | Cause | Repair |
|---|---|---|
| Constant running | Worn flapper or fill valve | Replace the part |
| Rocking toilet or water at base | Failed wax ring, loose bolts | Pull the toilet, replace the wax ring, reset |
| Cracked tank or bowl | Age or impact | Replace the toilet |
| Slow fill | Partly closed valve or clogged fill valve | Clean or replace the valve |
| Repeated clogs | Trap blockage or a drain line issue | Auger the toilet, check the line |
Toilet flange repair
The flange is the ring on the floor that anchors the toilet to the drain. A cracked or corroded flange lets the toilet rock, which breaks the wax seal and leaks. Repair kits and rings secure the toilet to a damaged flange, but a flange that has rotted away or sits below the floor needs a proper repair, sometimes with subfloor work.
InstallationInstalling a new toilet
A new toilet install covers removing the old one, checking the flange, setting a new wax ring, mounting the toilet, connecting a new supply line and testing for leaks. Bringing your own toilet is fine, and the plumber tells you if the rough-in distance fits.
Water-efficient models use less per flush, and the right height and bowl shape matter for comfort. Ask the plumber about your options when you call.
Local fitWhy toilets run and leak more in older homes
The City of Sanger's housing element reports about 29 percent of homes are more than 50 years old and 53 percent more than 30. Older toilets and older supply valves wear out. Shutoff valves that have not been turned in years can fail when you finally use them.
The city's water report lists chlorine between 0.92 and 1.4 ppm for 2024, a normal range for disinfection. Over years, chlorinated water and hard water wear rubber flappers and plastic fill valve parts, and a toilet more than ten years old often needs new internals.
What affects the price of toilet repair
Toilet repairs are inexpensive compared with the damage they prevent. We give a clear price before work starts.

A dispatcher is on the line 24/7 for emergency toilet repair.
What to do before the plumber arrives
- Turn the shutoff valve behind the toilet clockwise to stop the water.
- Lift the tank lid and raise the float if the bowl is rising.
- Do not flush again if the bowl is full.
- Wear gloves when clearing an overflow.
Standards for toilets
Toilets sold in California must meet state water efficiency standards, which are why current models use less water per flush than older ones. If a repair is not worth it, a replacement under the UPC-based plumbing code is a straightforward job.
