Fluidmaster "Ghost Flushing"

I've replaced the fill value and the flapper, and now the toilet runs for about three seconds every few minutes. When I turn off the water supply, the water in the tank lowers about 1 1/2" fairly rapidly (over an hour or so) but then stabilizes. So there is still ~6" of water in the tank and it remains at that level and has been for >24 hours.

So if I have a new valve and flapper, what could be causing the ghost flushing? Especially with the water level stabilizing after lowering 1 1/2"?

Thanks for the advice!

I should also include that the normal water level is about 1" below the top of the overflow tube and that the rubber line from the valve is not extending down the overflow tube but positioned above it using the Fluidmaster bracket.

Welcome to the forums..

The tube coming from the fill valve needs to clip on the top of the tube for the flush valve. If its stuck too far in the tube you get a siphon effect..

Is this possible your issue?

Please tell us the make of the toilet.

LOL we posted at the same time...

What toilet do you have and what flapper did you use?

Thanks. It is a 20+ year old Crane toilet. I am using the clip, so the rubber tube sits above the top of the overflow tube.

Tube is cracked most likely then. The flush valve would need replacement..

You can look in the tube and see if you see water flowing in there..

Do the dye test..

I did the dye test previously and water was flowing into the bowl which is why I replaced the flapper. What confused me was when I cut-off the water supply and the outflow stopped after lowering 1 1/2". So crack must be just above that mark? I will take a look. Thanks.

Duct tape it! LOl Actually I'm semi serious. Flush valves are a PITA to replace IMO. If you find a crack, some sort of hot glue, epoxy, silicone, Gorilla tape...would seal it up fine for a long time.

Heck, I have some duct tape holding down the overflow switch inside my dishwasher, been there for 4 months.
