Water on the amenities floor
In January 2026 we were called to a blocked drain in a commercial toilet block in Clarkson. When our tech arrived the tiles were wet and dirty around the floor waste, which is what you see when the line below a set of public toilets stops taking water and it has nowhere to go but back up.
Public amenities get more use in a day than a house toilet gets in a month, and the people using them don’t own them. So when a drain like this blocks, the question isn’t only “can we clear it” but “what’s actually in there”.
Getting in through the middle bathroom
There was a clean-out point in the middle bathroom, so that’s where we went in. A clean-out is a capped opening built into the drain so a jetter hose or camera can get straight into the line without pulling a toilet off the floor.
We ran the high-pressure jetter from there and cleared the drain. On a lot of jobs that’s where the story ends: water flows, the floor dries, everyone goes home. But a commercial drain that has blocked once will block again if the cause is still sitting in it, so the camera went down next.
What the camera found past the jump-up
Further down the line, past the jump-up, there was something metal stuck in the pipe. A jump-up is the vertical section where a property’s drain connects down to a deeper sewer main, and it’s a spot where anything solid travelling down the line tends to catch.
Our tech tried two ways to move it. The jet didn’t shift it. Bumping it with the camera head didn’t shift it either. It was wedged, and water pressure alone wasn’t going to change that.
Why the next step is a robotic cutter
The notes from the day are blunt: it requires a robotic cutter. That’s a remote-controlled cutting head that travels inside the pipe and grinds through an obstruction from the inside, guided by its own camera. It means the object can be cut out without breaking up the floor or digging down to the connection.
Leaving a lump of metal in a sewer line is a problem even when the drain is flowing. Paper and waste catch on it, build up behind it, and the block comes back. Clearing the water was the urgent part. Removing the metal is what stops the next call.

For anyone managing a commercial toilet block
- Water around a floor waste is a drain problem, not a cleaning problem. Mopping it up just hides the warning.
- Ask for a camera after the jetting. Jetting tells you the drain flows today. The camera tells you whether something is still in there.
- Solid objects don’t break down. Paper softens. Metal, plastic and hygiene products stay where they lodge until someone takes them out.
- A robotic cutter can save the floor. If something is jammed deep in the line, cutting it out from inside is usually far less disruptive than excavating.
