A toilet that flushes on its own — the phantom flush — is startling, but the cause is usually simple and fixable. Here is what is happening in Eugene homes.
The slow leak
A phantom flush happens when the flapper or the tank seal is slowly leaking. The water level drops until the fill valve kicks on, and the refill looks like a ghost flush. The toilet is not haunted — it is leaking.
Confirm the leak
The food-coloring test works here too: a few drops in the tank, no flushing, and check the bowl in 15 minutes. Color in the bowl means the flapper is letting water through.
Other causes
A fill valve that runs briefly every so often can also mimic a flush. rain and older housing stock mean corroded fittings and slow drains show up often In Eugene homes with variable water pressure, a worn fill valve seal is a common trigger.
The fix
Replace the flapper first — it is cheap and usually the culprit. If the ghost flush continues, the fill valve or the flush valve assembly is next in line.
Quiet the ghost
