A toilet that overflows or leaks onto the floor is an emergency, because water reaches subfloor and neighbors quickly. Reach behind the bowl, turn the small oval valve clockwise to stop the supply, then call our 24/7 line. We schedule same-day and after-hours visits when a plumber is available.
Toilet repair covers clogs, leaks at the base, loose or wobbling bowls, tanks that run or fill slowly, weak flushes and worn flappers. We also install new toilets and replace the supply line and wax ring when needed.
When a toilet problem is an emergency
Water on the floor, a bowl rising after the flush or sewage in a nearby tub means the toilet is not the only problem. Stop flushing and do not keep plunging. Repeated overflow points to a blocked drain line downstream.
If the toilet is on the second floor, shut its supply valve and also close the main water valve until the plumber is here. A slow leak through the floor can stain the ceiling below before you see it.
Water at the base
A failed wax ring, a loose closet bolt or a cracked flange lets water seep out when the toilet is flushed.
Weak flush
Mineral buildup in the rim jets, a low tank water level or a partial clog slows the swirl.
Constant running
A warped flapper or worn fill valve leaks tank water into the bowl and costs money on the bill.
Wobbly seat or bowl
Loose closet bolts or a rotted floor can rock the toilet and break the seal.
What a plunger can fix, and what it cannot
A flange plunger with a rubber flap suits a toilet drain. Seat it fully and push with steady strokes, ending with a pull. Most simple clogs clear in a few tries.
If water rises on the third stroke, or other fixtures gurgle, stop. The clog is deeper, and more force will only push wastewater into other drains. That is the time for a closet auger or a cable at the cleanout.
How we repair a toilet
Find the cause
We check the supply, the tank parts, the seal at the floor and the drain line.
Choose repair or replace
A flapper or fill valve costs little. A cracked bowl or an old toilet that clogs often may be better replaced.
Reset and seal
We reset the bowl on a new wax ring or foam seal and tighten the closet bolts evenly.
Flush test
We flush repeatedly and check the base and supply line for any weeping.

Local notes on toilets in Lemon Grove homes
About 47 percent of Lemon Grove homes are renter-occupied, based on 2020 Census figures. If you rent, tell your landlord in writing about a leaking base and keep the plumber's invoice. A slow leak that rots a subfloor is a bigger bill for everyone.
A running toilet can add noticeably to a bill from Helix Water District. A quick check is to add a few drops of food coloring to the tank. If color appears in the bowl without flushing, the flapper is leaking.
What toilet repair and installation cost
You see the total before we start. Water damage from a sudden overflow may be covered by insurance, but the toilet and routine wear are generally not.
