adjusting float in toilet tank does not change water level

When I turn the screw on the arm that holds the float clockwise, the floats ascends and the water will constantly flow into the fill pipe after filling up in the tank and will never shut off. It just keeps going into the fill pipe. If I turn the screw counterclockwise and lower the float down as far as it will go, the water will rise right to the edge of the fill pipe literally just a hair from flowing into it.

I can't seem to make it any lower. Could the float be broke? even when I have it at its lowest point the water will rise above the float (is this normal?).

any suggestions?

 

Try manually lifting up the float lever. When in the up position do you hear the flow of water stop? If you still hear water flowing when you're holding the float lever in the up position then you probably need a new fill valve.

 

If this is the old style ballcock with the float on a long arm, you can just bend the arm down a little to give you more adjustment range.

If it's the newer style where the float surrounds the fill valve, there is usually a coarse overall adjustment to get the height approximately right and then a fine adjustment screw to make the final adjustment.

The method for coarse adjustment varies depending on brand of fill valve. Often the top of the fill valve just turns to set coarse height. If you post a picture turn off the water and flush the tank first, we can advise further.

I think I adjusted the arm you were talking about but I'm not sure. here's some video:

I would replace that float assembly with a Fluidmaster 400 unit, as it appears the valve may be bad on yours. It may not be adjustable. Cost is negligible and it is an easy change out.

 

I'm going to give it a try and report back, thanks!

 

I don't know how the pros like them, but I've been using the floatless fill valves for about 30 years and I love them. Just replaced one in son's bath this morning, quite old and started to not shut off properly.

I'm a semi-pro. I tried the floatless valves when they came out in the 80's and had bad experiences with them not lasting. Then I found Fluidmaster and never looked back.

 

just wanted to let you guys know that I got a universal fill valve much like the 400 (or maybe it is the 400?) installed it with no problems and am able to adjust the water level easily and it doesn't make that squeaking noise after the tank fills up! thank you!
