What’s included
- Diagnose the source of a running toilet
- Remove old flapper and inspect seat for wear
- Install correct-size replacement flapper
- Adjust chain length for proper flush and closure
- Verify running stops and flush performs normally
How it works
Confirm the diagnosis
We lift the lid, observe the fill and drain cycle, and check whether the flapper, fill valve, or float is responsible for the running water.
Replace the flapper
We shut off the supply, flush the tank empty, unhook the old flapper, and snap on the correct replacement, adjusting the chain to the right length.
Test and confirm
We open the supply valve, let the tank fill, and listen and look to confirm the running has stopped and the flush is clean.
Problems we fix
- Toilet that runs for 30–60 seconds after every flush — a flapper not seating fully
- Toilet that runs continuously because the flapper has hardened or cracked
- Wrong-size replacement flapper installed, causing the same leak to continue
- Chain too short, holding the flapper off the seat permanently
Toilet Flapper Replacement in Charleston — FAQ
Can I diagnose this myself before calling?
Drop a few drops of food coloring in the tank without flushing. If color appears in the bowl within a few minutes, the flapper is leaking. That's your confirmation.
What if the flapper replacement doesn't stop the running?
If the seat (the surface the flapper rests on) is pitted or warped, a new flapper still won't seal. In that case, a full flush valve replacement fixes the problem — we assess and recommend on the spot.
Is a running toilet urgent?
Not a safety emergency, but a running toilet can waste several hundred gallons a week. It's worth addressing promptly — the fix is fast and inexpensive.
Toilet Flapper Replacement across Charleston
Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
