Adjust Water Level Toilet Tank Fluidmaster

A small adjustment to the water level in your toilet to the proper hei.

Adjust water level toilet tank fluidmaster. Then turn off the water supply to the toilet by rotating the knob on the wall behind the toilet clockwise as far as it will go. If the toilet is always running you ll be able to see the water pouring into the flush valve and this is a sign that the level is too high. Compare the water level with the line on the flush valve to see if the water is too high or low. So i decided to fix it myself.

Here s what i did to adjust the toilet tank water level. Check bowl water level by flushing toilet. Wait 1 minute until the bowl water level recedes down and stops. Most tanks have a water level line on the flush valve the pipe next to the fill valve where water flows out if it gets too high.

To adjust the level at which the leak guard triggers merely shorten or lengthen the chain used to connect the guard to your toilet s fill lever. This chain can be adjusted. Shortening the chain will make the leak guard more sensitive to potential leaks while adding slack to the chain will allow the system more leeway. To adjust the water level in your toilet bowl start by removing the tank lid and noting if the water level looks too high or low.

Since the height of the float determines the water level turn the screw on top of the fill valve 1 full rotation. If bowl appears to be full but continues to fill the valve may be overfilling the bowl causing excess water to siphon down the trap way. The fill valve uses a float that moves up and down the valve rather than a float ball. Doug cornwell s 60 second fix shows you how to adjust the water level in your toilet.

Adjusting the valve adjusts the amount of water that comes into the tank after flushing. Adjusting the toilet tank water level with a fluidmaster model 400 fill valve does not require turning off the water to the tank. Adjust the amount of water going into the bowl by using these steps. Recently my toilet had been running water longer than normal.

Once the water is off check the float which is a plastic ball attached to a long arm at the top of the fill valve.
