How to Adjust the Water Level in a Toilet?

Adjusting Toilet Water Levels

If you’re a homeowner you’re going to have to know how to troubleshoot simple things with a toilet that’s just the way it is. That’s why every homeowner should learn basic fixes for their toilets. Today, we’re going to talk about how to adjust the water level. It’s the only adjustment that changes your flushing force.

Why Would You Want to Change Flushing Force?

Your toilet bowl water level is more important than you believe. If it’s too low, there may not sufficient water to flush the toilet appropriately and you might end up with regular blockages. If it’s too much water in the bowl, your toilet can waste water by continuously running and might even end up being dangerously near to overrunning when you flush!

How to Raise the Water Level
Your toilet’s water level is controlled by a float that turns the water system on and off based on the water level in the tank (and in the bowl). To raise it, you’ll need to adjust the float, which will be among 2 kinds. Prior to doing anything, turn off the toilet’s water supply.

(note: Some toilet shut-off valves are so old they can get stuck or start leaking when they are moved. That being said you don’t want to start messing with this before bed on a Friday night. You’ll want to check it first thing in the morning so you’ll have time to have a plumber come out and replace it if you need to.)


The Ball & Arm Style Float
A Ball & Arm float is a plastic ball shape linked to a metal arm. You can adjust it by taking these actions:

  • Take a look at the float’s height in the tank when it’s full. The float must sit at the water level. Based on the height of the float, identify whether you wish to raise or lower the water level.
  • To adjust the water level, locate the screw connecting the float to the fill valve and turn it in little increments with a screwdriver to adjust the height of the float. Clockwise raises the water level and counterclockwise decreases it.
  • Test the water level by flushing it, and make further changes as required.

The Cylinder Style Float
This float, which looks like a plastic cylinder with a main opening going through the center, is a lot easier to adjust.

  • Find the modification stem, a long, slender tube that connects to the fill valve and typically runs parallel to the fill valve or extends horizontally from the top.
  • Locate the release clip on the changed stem, which links the float to the stem.
  • In lots of designs, you’ll pinch the release clip to raise or reduce the float.
  • If not, you’ll use a screwdriver to change the water level, turn clockwise to reduce it, and counterclockwise to raise it.
  • Test and make adjustments as needed.
