American Standard Vormax Slow Leak

[DavidLeXK]

New time homeowner, so now we're in charge of all of our fixes. We noticed our toilet running every hour or two, and noticed a very slight leak from the tank into the bowl. It's the vormax system which I've never seen before, so it has two flaps.

I've changed 3 different flaps, replaced the whole inside besides the fill valve. There is no water leaking on the outside of the toilet. All new seals and everything... Any help would be much appreciated! TIA.

For starters make sure the fill tube is kept higher than the overflow tube.

If the tubing is placed down the overflow it can siphon water from the tank.

As a test, turn off the stop valve at the wall. Does the water level continue to drop 3/4 inches? If it only drops 1/2 inch and stops, set the fill valve to fill one notch lower. What I suspect is happening is that your water level is set too high. Water creeps up that refill clip by capillary action, and then goes down the overflow tube.

A leaky flapper will cause the cycling that you describe, but your water level looks higher than normal. With a leaky flapper, the water level will continue to drop once you close the stop valve.

Not a plumber or a pro. I wonder if you have the water level set too high in the tank. A few year back, I had mine right up to the overflow pipe. Whenever someone would sit on the toilet, small amount of water would go down the overflow pipe and there would be a small phantom flush.
