Saniflo Not Working? What to Do Before Calling an Engineer

If your Saniflo has stopped working, do not flush the toilet or use any sink, shower or appliance connected to the unit. Turn off the water supply, safely isolate the electrical supply and follow the checks below before calling an engineer.

Step 1: Isolate the Water Supply

The first step is to stop water from flowing into your Saniflo unit. This prevents more water from entering the system and making the problem worse.

Locate the isolation valve – often behind the toilet or on the pipework feeding the Saniflo.

Step 2: Check the Toilet Water Level

Once the water is off, check the water level in the toilet pan.

• Inspect the water level. Look into the toilet pan to see if the water level is higher than usual. If so, it’s important to remove the excess water to prevent any risk of overflow.
• Bail out the excess water. Use a container or a small pump to remove the extra water until it reaches the normal level. Be cautious to avoid spillage.
• Monitor the level. After baling out, check to ensure the water level remains stable and does not rise again. This helps in ensuring that no additional water is entering the system while you proceed with troubleshooting.

Step 3: Isolate the Electrical Supply

With the water supply turned off, safely isolate the electrical supply to the Saniflo.

• If the unit has a switched fused spur, turn the switch off.
• If there is no switch, turn off the relevant circuit at the fuse box if you can identify it safely.
• Do not remove electrical faceplates or expose any wiring. If you are unsure, leave the electrical supply alone and explain this when booking the engineer.
