A running toilet wastes water every hour it runs. Most cases trace to a flapper that will not seal, a fill valve that will not shut off, or a float set too high.
CMH Plumbing Solutions handles toilet repairs through residential plumbing. Unexplained usage can also tie to high water bill detection. Call (469) 972-6679.
Quick diagnosis
- Water trickling into the bowl: often a flapper or flush valve seal
- Tank overfilling into the overflow tube: fill valve or float height
- Intermittent ghost flushing: leaking flapper slowly dropping the tank level
What you can try
Shut the supply valve and see if the sound stops. Remove the lid and watch a flush cycle. Do not force plastic parts. If parts are brittle or the tank sweats heavily from constant refill, schedule a plumber.
When professional repair is smarter
Cracked tanks, worn flush towers, or repeated failures after DIY parts are good reasons to call. We replace the right components and confirm the toilet fills and seals correctly.

What makes a toilet keep running
A running toilet usually means water is leaking from the tank into the bowl past a flapper, flush valve, or refill controls that never shut off. You hear it as a ghost flush, a constant hiss, or intermittent trickle. Left alone, it wastes a surprising amount of water and can stain the bowl.
CMH fixes running toilets as everyday residential plumbing. Many repairs are parts replacements inside the tank; cracked tanks or failed flush towers need a wider repair plan.
Quick diagnosis you can do safely
Remove the tank lid carefully and flush once while watching. If the flapper is warped or has mineral buildup, it may not seal. If the fill valve never stops, the float setting or valve itself may be at fault. Add a few drops of food coloring to the tank; if color appears in the bowl without flushing, the flapper or flush valve seat is leaking.
Shut the angle stop behind the toilet if the sound will not stop and you need quiet overnight. That buys time without wasting water until repair.
Parts that commonly fail
- Flappers that harden, warp, or misalign with the flush seat
- Fill valves that stick open or overfill into the overflow tube
- Flush valve seats pitted by minerals so no flapper can seal
- Floats that bind against tank walls on newer dual systems
- Supply lines and angle stops that seep at the connection
Throwing random kit parts at a stained overflow tube without cleaning the seat often fails. We replace what is worn and confirm a full seal through multiple flush cycles.
When DIY kits are not enough
Brittle tanks, continuously sweating tanks from never-ending refill, and repeated failures after recent DIY parts are good reasons to call. Some modern toilets use proprietary towers that are awkward without the right parts. If the toilet rocks or the wax seal smells, mention that; a running toilet and a failing seal sometimes travel together.
Constant running that coincides with a jumping water bill deserves a meter check as well. Rarely, other leaks contribute, and high water bill detection can separate toilet waste from hidden leaks.
Water waste and why it matters in DFW
A flapper leak can waste hundreds of gallons a month. In summer billing cycles that already reflect irrigation, a silent toilet leak hides inside the total. Fixing it is one of the fastest conservation wins in a bathroom.
Frequently asked questions
How long does a running toilet fix take?
Many flapper and fill valve repairs finish in a standard short visit once parts are matched to the toilet.
Can I just jiggle the handle?
Jiggling may reseat a flapper temporarily. If you jiggle daily, the part is failing and should be replaced.
Is a running toilet an emergency?
Usually not if you can shut the angle stop. Overflowing onto the floor is urgent.
Will you replace the whole toilet?
Only when the tank or bowl is cracked, obsolete, or repeatedly failing. Most running toilets need parts, not a full swap.
What if only a thin trickle runs?
Thin trickles still waste water and often grow worse. Schedule a fix rather than living with the sound.
