Introduction
The first time I experienced a power outage while using a smart toilet, I had no idea what to do. Unlike traditional toilets, many smart models rely on electric-powered flushing mechanisms, meaning they won’t work without power. That left me wondering—how do you flush a smart toilet when there’s no electricity?
Luckily, after some research and hands-on experience, I found several easy ways to flush a smart toilet manually. Whether your toilet has a manual flush button, battery backup, or requires a water-pouring method, this guide will show you exactly what to do.

By the end of this guide, you’ll know exactly what to do when the power goes out—so you’re never stuck with an unflushable toilet again!
Does a Smart Toilet Need Power to Flush?
Not all smart toilets rely entirely on electricity for flushing. Understanding the difference between tank-based and tankless models will help you determine whether your smart toilet can still flush during a power outage.
🚽 Tank-Based vs. Tankless Smart Toilets
Smart Toilet Type | Flushes Without Power? | Why? |
Tank-Based Smart Toilets | ✅ Yes (sometimes) | Uses stored water in the tank for gravity-fed flushing. |
Tankless Smart Toilets | ❌ No | Requires an electric pump for flushing. |
✔ Tank-based smart toilets store water in a tank and use gravity-fed flushing, meaning they may still function without power.
✔ Tankless smart toilets rely on electric water pumps, so they won’t flush unless a backup power source is available.
📌 Tip: Check your smart toilet model’s manual to see if it includes a manual flushing option.
🔋 Do Some Smart Toilets Have Battery Backup?
✔ Some high-end smart toilets come with built-in battery backup systems to allow limited flushing during power outages.
✔ If your smart toilet supports battery-powered flushing, you may need to activate emergency mode manually.
📌 Tip: If your toilet doesn’t have a built-in battery, consider an external backup power source for future outages.
Step-by-Step: How to Manually Flush a Smart Toilet Without Power
If your smart toilet doesn’t flush automatically during a power outage, don’t panic! Here are three methods to flush it manually.
🚽 Method 1: Using the Manual Flush Button (For most smart toilets)
✔ Many smart toilets have a hidden manual flush button or lever that works even without power.
How to Find It:
- Check the side or base of the toilet—some models have a small flush button near the bowl.
- Look near the back of the toilet where the water supply connects.
- If unsure, refer to your toilet’s manual for the exact location.
📌 Tip: If your toilet has a dual-flush button, pressing it will still release stored water if it’s a tank-based model.
💦 Method 2: Pouring Water Directly Into the Bowl (For tankless and water-pump-dependent smart toilets)
✔ If your smart toilet doesn’t have a manual flush button, you can force a flush by pouring water into the bowl.
How to Do It:
- Fill a large bucket with at least 1 gallon (4 liters) of water.
- Pour the water quickly but steadily into the toilet bowl.
- The water pressure should force a flush down the drain.
📌 Tip: Use warm water if available—cold water may cause sudden splashing.
🔋 Method 3: Using Battery Backup (If Available)
✔ Some premium smart toilets have battery-powered flushing systems for emergencies.
How to Activate It:
- Locate the battery compartment (usually under the toilet seat or inside the side panel).
- Insert fresh batteries (if required) and switch to backup mode.
- Try pressing the flush button on the toilet or remote control.
📌 Tip: If your toilet doesn’t have built-in battery backup, consider using a portable power bank or small generator for emergency power.
📌 Summary Table: How to Manually Flush a Smart Toilet
Method | Best For | Steps |
Manual Flush Button | Most smart toilets | Locate the manual button on the side or base of the toilet. |
Pouring Water into Bowl | Tankless & power-dependent toilets | Pour at least 1 gallon of water directly into the bowl. |
Battery Backup | Smart toilets with built-in battery options | Insert batteries, switch to backup mode, and press flush. |
📌 Tip: Check your toilet model’s manual to determine which method applies.
Alternative Emergency Solutions for Smart Toilets
If power outages are common in your area, it’s best to prepare ahead of time to avoid being stuck with a non-flushing smart toilet. Here are some practical solutions to ensure your toilet works even when the electricity goes out.
🔋 1. Use an External Power Bank or Backup Generator
✔ Many smart toilets use low-voltage power, meaning they can be powered temporarily with a portable power bank or small generator.
How to Set It Up:
- Check your toilet’s power requirements (voltage and wattage).
- Use a portable power bank with the correct voltage and plug type.
- If using a generator, make sure it’s safe for indoor use.
- Plug the toilet into the backup power source and use normally.
📌 Tip: Some smart toilets have USB-powered emergency flushing, which makes them compatible with power banks.
🚰 2. Store Emergency Water for Manual Flushing
✔ If you have a tankless smart toilet, you won’t have stored water for flushing.
✔ Keep a few gallons of water in containers for emergencies.
How to Use It:
- Fill a large bucket with clean water.
- Pour at least 1 gallon (4 liters) into the toilet bowl to force a flush.
- Store extra water in case of longer power outages.
📌 Tip: If possible, store filtered water to prevent mineral buildup inside the toilet bowl.
🔌 3. Upgrade to a Smart Toilet with Battery Backup
✔ Some smart toilets come with built-in battery backup systems.
✔ These models allow you to flush normally for a limited number of uses.
How It Works:
- Battery backup activates automatically when power is lost.
- You can flush a limited number of times (depends on the model).
- Once power is restored, the system recharges itself.
📌 Tip: If you’re buying a new smart toilet, look for models with emergency battery flushing.
🚽 4. Install an Emergency Gravity-Flush Water Tank
✔ If you’re renovating your bathroom, consider adding a secondary water tank for emergency use.
How It Works:
- A small overhead water tank is connected to the toilet.
- When power is out, you can manually open the valve to allow gravity flushing.
- Works with both smart and traditional toilets.
📌 Tip: This is an ideal solution for homes with frequent power outages.
