What Should I Do If My Toilet Pipes Freeze?

Winter weather can freeze water pipes faster than many homeowners expect. When this happens, your toilet may stop flushing, the tank may not refill, or you may notice little to no water flow. If left untreated, frozen pipes can crack or burst, leading to costly water damage.

The good news is that you can often thaw frozen toilet pipes safely if you act quickly and use the right methods.

What Happens When Toilet Pipes Freeze?

Toilet pipes freeze when water inside the pipe turns to ice. As the ice expands, it blocks the flow of water. In some cases, the pressure created by the ice can split the pipe.

Frozen toilet pipes are most common in:

• Bathrooms along exterior walls
• Unheated basements
• Crawl spaces
• Cabins and vacation homes
• Mobile homes
• Buildings left vacant during winter

If your toilet suddenly stops working during freezing weather, frozen pipes are one of the first things to check.

How Can You Tell If Your Toilet Pipes Are Frozen?

Several warning signs can point to frozen pipes.

Look for:

• The toilet tank does not refill after flushing.
• Little or no water comes from the supply line.
• The toilet will not flush normally.
• Frost appears on exposed pipes.
• Strange odors come from the drain because wastewater cannot move properly.

If multiple plumbing fixtures stop working at the same time, the frozen section may be located farther inside your plumbing system.

What Is The First Step You Must Take?

Prevention of water damage comes first.

These steps must be taken before you start thawing out the frozen pipe:

• Turn off the water valve on the toilet.
• If several faucets are frozen, turn off the main water valve in your house.
• Do not force flushes repeatedly.
• Turn on any adjacent faucets that use the same plumbing line. This will reduce the pressure as the ice thaws.

Doing this reduces the risk of bursting the pipe when the water starts flowing again.

How Do You Thaw Frozen Pipes In Your Toilet Safely?

It is better to defrost gradually. Do not be tempted to do rapid defrosting using high temperatures.

Hair Dryer

The typical hair dryer that we keep in our homes is a great way to thaw exposed pipes.

• Make sure you move it while defrosting.
• Always ensure the dryer is kept several inches away from the pipe.

Begin defrosting from the end and go to the frozen part.

Warm Towels

Wet some towels in hot water, then drain them and cover the frozen pipe with them.

Continue replacing the towels when they get cold until the water starts running.

Heating Pad or Heat Tape

The heating pad or the heat tape can thaw frozen plumbing gradually.

Make sure you follow the instructions provided by the manufacturer before using any electrical heating products near plumbing.

Increase The Temperature In The Room

In some cases, the frozen portion of the pipe may be located inside the walls of the bathroom that are cold.

One can simply open the cabinets, the door of the bathroom, and set up a space heater inside the room.

What Should You Never Do?

Several reasons why pipes burst are due to the use of dangerous thawing techniques.

Don’t:

• Use open flames
• Use propane or blow torches
• Pour boiling water directly on pipes
• Use charcoal heaters
• Use heat guns that produce high temperatures

The pipes could burst, or there might be a fire risk from rapid heating.

What If the Toilet Drain Is Frozen?

In some cases, the supply pipe is working perfectly well; however, the drain pipe or toilet trap freezes.

If that occurs, carefully pour hot water into the toilet bowl.

Wait for several minutes before trying again.

It may take several attempts to restore proper drainage.

If the toilet remains clogged despite your efforts, do not use the toilet until the pipe has fully defrosted or been checked by a plumber.

Inspect Pipes for Damage When Ice Thawing

When water is flowing again, thoroughly inspect the pipes.

Check for:

• Water leaking from the pipes
• Tiny cracks
• Wet walls/floors
• Water marks
• Low water pressure

Any minor crack may lead to a more serious leak in the future.

In case of damage, turn off the water supply and call a licensed plumber before using the toilet.

Other Reasons that Toilets Fail in Winter Aside from Frozen Plumbing Pipes

Frozen pipes may be a cause of toilets being out of service during winter; however, they are not the only reason. Some vacation cottages, hunting camps, workshops, boats, and off-the-grid homes have plumbing problems due to years of exposure to freezing temperatures.

For places that have recurrent freezing pipe problems, some homeowners opt to try something else instead. An electric incinerating toilet like the Incinolet does not use any water, pipes, drain pipes, septic system, or sewer hookup. The absence of water in the pipes means there is nothing that will freeze in cold weather.

How to Keep the Pipes of Your Toilet From Freezing?

With just a little effort, you can ensure the safety of your plumbing system when the weather turns cold.

• Wrap exposed water lines with foam pipe insulation.
• Set your home’s thermostat to keep the temperature inside 55°F or above, even when you are not there.
• Fill any openings of your house through which cold air may be coming in with window caulk, door sweeps, and weather-stripping.
• Leave open the cabinet doors under your bathroom sink to let the warm air reach the pipes.
• Have your faucets running a bit if you live in an area with extremely cold temperatures.
• If you plan to leave your seasonal home, switch off the water supply.

When Do You Need to Contact a Plumber?

There are certain instances where you will need professional assistance.

A plumber should be contacted when:

• You feel there is a possibility that the pipe has burst.
• Water is leaking from walls, ceilings, or floors.
• The pipe is frozen but out of reach.
• The plumbing fixtures are not functioning.
• Thawing efforts have failed, and the pipe is still frozen.

A Solution Without Water For Cold Weather Regions

If you are troubled with freezing of the plumbing in your cabin, cottage, workshop, or holiday home during winters, then you can consider getting rid of water from your toilet system.

Incinolet electric incinerating toilet works without the need for any water, drain lines, septic tank, or sewer connection. Instead of flushing the waste through the plumbing system, electric heat is used to convert the waste into a small quantity of sterile ash.

As there are no toilet pipes filled with water, there will be no threat of freezing anymore. Therefore, Incinolet would make a great choice for off-the-grid homes, mountain cabins, houseboats, basements, garages, tiny houses, and similar places where winter weather creates plumbing issues.

Made in America for over 65 years, Incinolet has gained the confidence of people seeking a reliable waterless toilet system.

Final Thoughts

Frozen toilet pipes can put your schedule in jeopardy and become a major expense if not dealt with properly. It is important to act immediately to defrost them and to watch out for leaks, thus protecting your pipes. If you have frozen pipes often, consider replacing them with a waterless toilet.
