How to Adjust the Water Level in a Kohler Toilet Bowl

Are you forced to pour water into the Kohler toilet after flushing because the first time wasn’t enough? Do you have to wait to flush a second time? When that happens, the culprit is usually a low water level. Where? You guessed it — in the toilet bowl.

How to Adjust the Water Level in a Kohler Toilet BowlWhen this happens, many people think they need to call a plumber. Yes, most of the times you need professional repair.

However, you can typically take care of low water levels yourself by making a few adjustments. If this troubleshooting doesn’t work, then you should call a plumber because it may be more than a water level issue.

If you find that cracks are causing the leaks, consider a replacement. Other possibilities include clogged pipes or an obstruction. Try to remove the obstruction and flush to see if that clears the problem.

That, however, isn’t our focus for this post. Continue reading to learn how to check the water level and if necessary, make adjustments to resolve the problem.

How Should You Start?

Step 1: Remove the tank lid

Check to see if the water level is at the proper level.

Step 2: Check if the water fills to the required level

Locate the float valve, which is a tube attached to a ball. Its function is to adjust the tank’s fill rate. It also affects water movement into the bowl.

Step 3: Re-adjust the water flow

Re-adjusting the water flow into the tank should resolve any issues with low water levels after flushing.

Push the ballcock back a little to increase the flow and height of the water.

Where you find an adjustment clip attached, squeeze and slide in either direction. Push forward to increase and outward to achieve results similar to those above. The float valve helps with inflow to the rim feed hoses.

They, in turn, feed into the rim holes and drain into the bowl. Every time you use the toilet, a certain amount of water remains in the bowl.

Step 4: Adjust the flow into the rim holes

The rim holes receive water from the flush valve into the tank. You should adjust this valve to assist the rim holes.

Resolve this by fixing it into the correct position. Pull it up and insert it into the drain within the canister.

For canister-type filling toilets, insert the tube into the hose feed centrally located in the canister.

Never leave the valve hanging in the canister.

Some toilets use a system of flapper valves. Connect the water pipe next to the ballcock into the flush valve. As noted, never leave the valve hanging in the water tank. The next step is to test if the above measures have helped adjust the water level.

Step 5: Flush

Simply flush the toilet. The water tank should refill to the desired level.

The water in the bowl should also fill to the correct level.

Step 6: Cover the water tank

You don’t want anything falling into the water tank and causing clogs that may affect the toilet’s function.
