Installing a Toilet Tank Bag


Installing a toilet tank bag(s) is a great way to save water in your home. For every bag you install you could save up to 0.8 gallons per flush! Plus, you won’t have to change any of your use habits to be more efficient. Just follow these steps to start saving water today.

Things you’ll need:

  • Toilet tank bag(s)
  • Towel

Instructions: installing the toilet tank bag

1. Open the back of the toilet. Remove the lid from the tank area of the toilet and set it aside.

2. Fill the tank bag. You can fill the bag to the desired level prior to putting it in the back of the tank. Or you can simply open the valve on the tank bag and slowly submerge it into the back of the toilet tank to fill it with water. How full do you want the bag? It’s a tough question, since it will depend on a number of site-specific factors including type of toilet and water pressure in the house. Filling the tank bag all the way may not leave you with enough water to clear the bowl every time you flush. If this turns out to be the case, you’ll simply pour out some of the water from the tank bag. But for now, fill it to the top and close the valve. Just remember to make sure you get all the air out of the bag, otherwise it’ll float and interfere with the flushing mechanisms.

3. Hang the bag inside the tank. The tank bag has a plastic hanger at the top. Simply loop that over the side of the toilet tank wall that is farthest away from the mechanisms in the toilet tank (to make sure it doesn’t interfere with the operation).

4. Give your toilet a test flush. Take a few pieces of toilet paper and toss them into the bowl of the toilet. Now, give your toilet a flush. As the toilet is flushing check that both the toilet paper in the bowl and water in the tank clear fully. Also, be sure that the tank bag doesn’t interfere with any of the toilets moving parts. If your toilet is working, you’ve successfully installed your tank bag! Now grab the lid to the tank and gently place it back on top of the toilet.

5. Educate the users. The possibility that a big #2 won’t flush all the way always exists, but the possibility grows if you are reducing the amount of water used. Luckily, the toilet tank bag is easy to adjust. Simply remove the lid of the tank, open the valve of the tank bag, and push some of the water out of it. At some point, you and/or the other users of the toilet will find the perfect level for everyone in the household. Even if that’s just .5 Liters, you’re still saving half a liter of water EVERY time the toilet flushes.
