Why Is My Saniflo Toilet Running? The 5 Most Common Causes And How To Fix Them!

Saniflo toilets are a convenient and efficient solution for bathrooms that lack a traditional drainage system. However, like any appliance, they can occasionally experience issues, one of which is intermittent running. This guide delves into the potential causes behind this problem and provides actionable steps to resolve it.

Causes of Intermittent Running

1. Faulty Check Valve

The check valve prevents wastewater from flowing back into the toilet. If it becomes damaged or clogged, it can allow water to leak past, causing the toilet to run intermittently.

2. Malfunctioning Float Switch

The float switch activates the pump when the water level in the toilet bowl rises. A malfunctioning float switch can send incorrect signals, leading to the pump running unnecessarily.

3. Damaged Pump

The pump is the heart of the Saniflo system, responsible for pumping wastewater to the drain. A damaged pump can fail to operate properly, resulting in intermittent running.

4. Clogged Toilet

Like any toilet, Saniflo toilets can become clogged with debris, such as toilet paper or hair. A clogged toilet can obstruct the flow of wastewater, causing the pump to run continuously.

5. Air Lock

An air lock occurs when air gets trapped in the discharge pipe. This can prevent wastewater from flowing freely, causing the toilet to run intermittently.

6. Electrical Issues

Saniflo toilets rely on electricity to operate. A faulty electrical connection or a blown fuse can disrupt the power supply, leading to intermittent running.

7. Incorrect Installation

Improper installation can also contribute to intermittent running. For instance, if the discharge pipe is not properly connected or if the toilet is not level, it can affect the performance of the pump.

Troubleshooting and Resolution

1. Check the Check Valve

Inspect the check valve for any damage or debris. Clean or replace it if necessary.

2. Test the Float Switch

Move the float switch up and down to ensure it moves freely. Replace it if it does not activate the pump properly.

3. Inspect the Pump

Listen for any unusual noises or vibrations coming from the pump. If the pump is damaged, it will need to be replaced.

4. Clear the Clog

Use a plunger or a drain snake to clear any clogs in the toilet.

5. Eliminate Air Locks

Disconnect the discharge pipe and pour a gallon of water into the toilet. If the water drains quickly, an air lock was present.

6. Check Electrical Connections

Ensure that the toilet is properly connected to a power source. Inspect the wires and fuse for any damage.

7. Re-install the Toilet

If the issue persists, consider re-installing the toilet according to the manufacturer’s instructions.

Prevention Tips

• Regularly clean the check valve to prevent clogging.
• Keep the toilet bowl free of debris.
• Avoid flushing non-flushable items, such as wipes or feminine hygiene products.
• Have the Saniflo system serviced by a qualified plumber annually.

Alternative Solutions

If the troubleshooting steps do not resolve the intermittent running issue, consider the following alternatives:

• Replace the Saniflo system with a traditional toilet.
• Install a macerator pump to assist with wastewater disposal.
• Contact a plumbing professional for further assistance.
