I recently replaced both my toilets' fill valves and flappers to resolve some running water/leaking issues - which was fixed on both toilets. The toilets are Kohler 1.6 gpf models.
But now my problem is that the bowl water fill level is about an inch lower than it used to be.
As soon as the bowl is finished filling (which seems to be at a normal level initially) - the water level immediately drops about 1-1.5 inches and then stays there.
Here's the things I've tried from other research without much success:
--------------------------------------------------
I don't see any external leaks around the toilet.
I’ve checked that the flapper chain has enough play for the flapper.
I've checked that the fill valve hose is positioned correctly.
I've raised the fill valve floater to as high is it can be while maintaining the water line to where it should be.
I've tried "slowing" down the water fill by turning down water pressure. Some say a tank that fills to fast won't allow the bowl to fill to normal capacity.
I've checked the little holes along the toilet rim and they seem to not be clogged/blocked.
I've forced the trap to clear by turning off the water while pouring multiple gallons of water down the toilet which flushes with good amount of force - so
There doesn't seem to be any clogs there.
I have not checked the vent on the roof to see if it blocked which would might cause siphoning in the toilets - but I don't think this is it because if it was - wouldn't the water level in the toilet bowls drop much more? The drop in level I see is relatively small - but still not as high as it should be.
--------------------------------------------------
I used the Fluidmaster 400A fill valve kit and
Flappers as the replacements on both Kohler 1.6 gpf toilets.
I'm running out of ideas, any suggestions on what else to check or what could be the cause?
Thanks
