How to Easily Remove Water from a Toilet

Whether removing a toilet for a new installation or bathroom floor renovation, you must begin by getting rid of the water inside the bowl. Even if you are installing a new wax ring or closet flange, it is crucial to prep your toilet for these types of repair jobs as well.

If left untouched, water can easily splash out of the bowl when removing a toilet from its flange, creating an unwanted mess in your bathroom and potentially causing permanent water damage to tile, substrates or drywall. Fortunately, this issue can be avoided with a few simple steps and products.


Although there are different toilet water removal methods to choose from, we recommend using a water absorber, like LiquiLock Water Absorbing Crystals. LiquiLock transforms water into a gel within minutes, which quickly dissolves and becomes flushable once water is added back into the toilet. It’s a hassle-free and timely way to ensure all water is removed from a bowl. Additionally, LiquiLock is sanitary, non-toxic, biodegradable and septic safe. 

You can also try using a sponge and bucket to empty water in the bowl, but there will likely be some liquid left behind in the Trapway. Additionally, while this “absorb and dump” method may be economical, it can be tedious and the least hygienic option because you must insert your hands directly into the toilet bowl.    

Some plumbers also prefer using a shop vacuum to quickly suck water out of a toilet. This method is effective; however, your shop vacuum will need to be thoroughly disinfected after each use.  


Here are step-by-step instructions about how to effectively use LiquiLock to remove remaining water from your toilet. If using another water absorber, refer to the manufacturer’s instructions located on the back of the product to ensure safety and effectiveness.

Step One

Turn Off Water

Shut off the water supply to the toilet by turning the valve in a clockwise direction. The water shutoff valve should be located behind the toilet on the left side. If the valve is not located there, it is likely in the basement or crawl space of your home (area between the ground and the first floor).

Step Two


Remove the tank lid and flush the toilet. You should hold the handle down to ensure the maximum amount of water drains from the tank and bowl.

Step Three


Empty entire packet of LiquiLock into the water. For 3 ½  GPF (gallons per flush) or larger toilets, use two packets of LiquiLock and pour simultaneously into the bowl. When using a bulk size of LiquiLock, fill the top thread of the cap and empty the powder into the bowl. For 3 ½ GPF or larger toilets, pour two caps full of LiquiLock into the bowl at the same time. 

Pro Tip: Your toilet’s GPF rating is typically stamped on the bowl in front of the tank.

Step Four


Wait at least four minutes and allow water to fully solidify. Then, carefully remove the toilet keeping it eye level to prevent any residual water from spilling out of the Trapway.

Once you’ve finished reinstalling your toilet, reconnect and turn on the water supply line. Allow your toilet tank to fill with water and then flush. Let the LiquiLock sit for about three minutes while water liquifies and becomes flushable.
