I have an old toilet, so this may not be possible but how would I reduce the amount of water in the toilet bowl? I was able to reduce the amount of water in the tank.

 

Are you trying to reduce the amount of water it uses on each flush or are you trying to empty the water out so you can work on it?

The water level in the tank is adjustable (as you already know) but the level in the bowl cannot be adjusted. It is determined by the trap that is cast into the bowl.

 

I am not trying to work on it. I had another toilet in m previous residence that was 3 or 4 years old and you can adjust the height of the water on the toilet bowl. I guess that is not a common feature?

 

I too have never seen a toilet where the level can be altered, since the water level comes up to the top of the trap inside the toilet.

But there are ways you can can keep from needlessly wasting water from a big tanked toilet.

1. You can put a brick or fill a quart milk jug with rocks and water, and stand in the corner of the toilet tank. That will allow the water level height to remain the same as normal, but with less water in the tank. Since the height is the same, the pressure exiting the tank into the toilet bowl's jet, will yield the same force.

2.You can use a flapper that you can adjust how long the flapper stays open for. They sell these at home centers for a couple dollars more

3. You can partially obstruct the fill valve's toilet bowl water recovery tube that sits above or plugs into the toilet tank's overflow tube. On most older toilets I have seen, that recovery volume is way to unnecessary! You want a certain amount to clean up the water with fresh. But usually that recovery water tube sprays way too much out of it.

4. You can buy a more expensive version of the same most popular replacement fill valve, that solves some of these waste water problems.

 

Have to agree with the other post, there is no way to adjust the water in a toilet bowl that I know off.
