Your plumbing system might run on electricity. However, will toilets flush without power?

Power outages can be dangerous. You may feel vulnerable if you use candles at night. Your plumbing system is another aspect of a power cut that you might not have considered.

Your water might still be able to flow, but your toilet won’t work if there is no electricity. You should prepare for the possibility of a planned outage by knowing what other parts of your house will be affected.

Final Flush

Each toilet has a final flush. This is the final flush of water in the tank. It allows you to flush the toilet once more even if power or water is not available.

This is because the toilet will automatically refill after each flush. There will also be an emergency fund in the tank to cover any unexpected situations. You can only flush one toilet at a time. You can also fill the tank with extra water and flush the toilet using that.

City Water when the Power is out

Your water might not work if you live outside the city limits.

If you Live in a House

Water from cities typically comes from wells and rivers. If the power goes out, water will likely be available to you if you live within city limits. Because water flows by gravity, it will be available to your home. Only the water in the main towers is available during a power outage.

Apartment Living

If you live in an apartment complex with multiple floors, your water supply will not work in the event of a power cut. Because there is usually an underground water pump system, water can’t be pumped up without power.

Well water when the power is out

You may not be able to use your well water in an outage. Because most well pumps run on electricity, this is because they are powered by electricity. A reservoir can hold between 10 and 50 gallons. You will still have water after the supply ends in this instance.

Appliances that will work even when the power is out

If you live in an apartment and have city water, it is likely that your water supply will not be interrupted by a power cut. You will not be able to use plumbing appliances that are powered by electricity, however.


Your sinks should work as normal if you live in a house that gets its water from the city. Your home may not have hot water, but it will depend on what type of water heater you have.

Tank water heaters

Traditional tank-type water heaters might be able to allow you to use hot water during power outages. You will only have a small amount of hot water and it will not keep warm for more than one to two hours.

Because gas and electric water heaters both use the same process, gas heaters need electricity to ignite the pilot and keep your water flowing. Is this the right recommendation? It is a good idea to take a quick shower after the power goes off and then wait for it to come back on within the next 12-24 hours.

Appliances that won’t work when the power is out

Sump pumps

Sump pumps require power to work properly. This can cause serious problems if there is a power outage. It is very dangerous to not have a sump pump in your basement to prevent it from flooding, especially if the power goes out due to a storm.

Tankless Water Heaters

This appliance is very useful when the power is off. These appliances provide hot water, allowing you to live in modern times. They will not provide hot water if there is an outage.

Pump-Assisted Sewer Systems

Many sewer systems work by gravity. Therefore, there shouldn’t be any problem during an outage. If your sewer pipes are powered by an electric pump, you shouldn’t flush the toilet faster than necessary. You could cause waste to back up, which can lead to overflowing into your home.

There are potential plumbing risks during a power outage

A power outage can bring about many plumbing problems. These could include flooding in basements, sewer backup, and frozen pipes. We have already discussed sewer backup and flooding in the basement, but frozen pipes can also be a threat.

Your pipes will still have water even if the power goes out. You may have to empty your pipes if it is cold outside during the blackout to prevent them from freezing. You risk your pipes bursting if you don’t do this. This is because water expands when it freezes.

Older homes are more at risk from frozen pipes because they aren’t as well insulated as new pipes. You should check your garage and outside plumbing for any pipes that may not be insulated. To prevent freezing, wrap them in blankets, foam, and towels.

How to prepare for a power outage

You can prepare for a power outage if you are aware of it.

Always have water with you

You should fill as many containers with water as you can. To flush your toilets, you should also fill up your bathtub.

Store Drinking Water

You should have at least one to two gallons of drinking water for every person in your home.

Find out where the water switches are located

These should include the main water shutoff and breaker panel as well as pump system switches. You should have a flashlight at each of these places.

Steps to take in the event of a power outage

  • To avoid an electric surge, turn off the breaker switch.
  • To avoid a tank drain, turn off the main water supply to your home.
  • Purchase a generator
  • Test your sump pumps if you have them.
  • Unplug your filtration system to disconnect it.
  • Turn off an electric water heater

What’s a Generator Used For?

Generators are a backup power source for your appliances in the event of an outage. You can use generators to power your sump pump and water heater as well as other appliances.

Can I fill my toilet tank with water to flush the toilet during a power outage?

The best thing about toilets is that they can still function by simply pressing the handle. You can fill the tank with water and flush it if there is no power.

This method is not ideal if you lose power for more than 24 hours. You will need to be careful with your electric sewer system. It might stop working and become blocked.
