How to Fix Low Water Level in a Toilet Bowl

Whether you like to admit it or not, your toilet is probably one of your favorite features of your home. It’s practical, it keeps your home sanitary, and it allows you to do your business in a relatively comfortable position.

However, if the water levels in your toilet bowl are low, flushing is not going to do much to get rid of unwanted… deuce matter.

So what can you do when the water’s as shallow as the Kardashians?

Luckily for you, we’re here to help!

How to Fix Low Water Level in a Toilet Bowl in 8 Steps

Before getting started, you’ll need the following materials:


  • New fill valve (buy at any hardware store)
  • Pliers
  • Container


Step 1. Shut off the water supply. If you’re a rookie, it’s the turn knob you can see sticking out of the wall right under the toilet tank.

Step 2. Flush the toilet. If the tank is full of water, you’ll just get it all over the bathroom floor during the next step of this nifty list.

Step 3. Unscrew the water hose from the tank. Use a wrench to loosen the lock nut holding the water hose to the bottom of the tank. When it comes off, pull it apart from the bottom of the toilet’s fill valve.

Step 4. Remove the fill valve from the tank. Before removing it, though, place the container previously mentioned under the hole that connects the water hose to the fill valve.

Step 5. Adjust the height of your new fill valve. Not all toilets are created equal. Prior to installing your new fill valve, make sure you’ve adjusted the size to fill your tank.

Step 6. Install the new fill valve. Do this by inserting its base into the hole where the old valve was in place. Secure it by screwing the previously removed lock nut under the tank. Use pliers to tighten it as much as possible. Then go back to the tank and place the new valve’s refill hose into the overflow tube.

Step 7. Reattach the water supply hose. Once this step is completed, turn the toilet’s water supply back on.

Step 8. Flush the toilet. Watch with a heart full of joy as your toilet bowl’s water levels rise to the occasion.

Don’t tell your family about it, they can all go use another toilet while you revel in the knowledge that you can sit on the one you just fixed for as long as you want.
