Before using antifreeze in a toilet, make sure to flush out all the water from the toilet tank. Draining all the water is very important for the process to work fine. If you pour the antifreeze in the water, the antifreeze will not work as well.

Once the toilet tank is clear, pour a handful of antifreeze – that is made of propylene glycol, not ethylene glycol, and mix it with the water that is remaining in the water tank. Now add only about a pint of non-diluted antifreeze in the toilet tank.

How to add antifreeze to the toilet?

Here’s what you can do to add antifreeze to the toilet:

Turn off the water supply and drain the water tank:

The first step involves turning off the water supply and draining the toilet water tank completely.

You are supposed to find the service valve on the basement wall of your home. Simply turn off the main water source and proceed to the next steps.

Flush all the toilets:

Now you should flush all the toilets. Before you do that, make sure to open all the indoor faucets. Follow this step for both the indoor and outdoor sides.

Now you will have to flush all the toilets in order to drain the water out of the toilet tank. At this point, you will have to pour some antifreeze, one that contains propylene glycol and not ethylene glycol.

Pour the antifreeze:

To ensure the right application of this step, you will first need to make sure that you are using the right antifreeze.

Pour the antifreeze into the tank and mix it with the remaining water. You will then have to pour one pint of non-diluted antifreeze into the remaining water of the toilet tank.

Make sure to use antifreeze water safety glasses while you follow this step. This will keep you safe from the water of the toilet tank, in case it splashes. In addition, make sure to always use non-toxic antifreeze in your toilet tank to avoid any unwanted incidence.

How to winterize an outdoor bathroom & toilet?

Now you should remove the top of the toilet tank and drain the water tank. Press the handle of the toilet flush and drain out the water. This flush will push out all the flush out of the water tank.

Now that the water from the toilet tank is depleted, the bowl is quite dry. You should use a towel or a washcloth to dry out the remaining water from the tank. Now pour the antifreeze into the toilet bowl.

Make sure to use an antifreeze that contains ingredients such as propylene glycol, not ethylene glycol. The latter is toxic and is used in car radiators.

In order to avoid any accidents, use the former antifreeze and wait for it to work its charm on your outdoor bathroom and toilet. Simply follow these steps to winterize an outdoor bathroom and toilet.
