We’re called to macerator faults fairly regularly across this part of London — properties in West Brompton often have bathrooms that rely on these systems because conventional gravity drainage simply isn’t an option. When this residential call came in, the toilet was completely out of action. Here’s what we found and how we sorted it.
What the problem was
When we arrived, the Saniflo had failed entirely. Waste had backed up into the toilet bowl and the surrounding pipework, leaving the system totally unusable. There was also a blockage further along the waste pipe — which was actually the first thing we needed to deal with. Fitting a new macerator onto a blocked pipe would’ve just caused the replacement unit to fail in exactly the same way.
Space behind the toilet was tight, so we had to work carefully to avoid disturbing existing fittings. The client had been wondering whether the unit could be repaired rather than replaced, and was understandably concerned about smells and the possibility of longer-term damage.
Why replacement was the right call
Once we’d assessed the unit properly, it was clear the internal mechanism had failed beyond repair. Macerators don’t last forever, and patching a failed unit isn’t a reliable fix. A new Saniflo was the correct solution — and the client was relieved to know it would actually resolve the problem properly rather than just delay it.
How we approached the job
We started by isolating the electrics at the fused spur and shutting off the water supply. Before pulling the old unit out, we used a wet vac to empty the failed macerator — skipping that step in a tight space like this one would’ve made the job far messier than it needed to be.
With the old unit removed, we rodded the waste pipe and used chemicals to fully break down the blockage. We weren’t satisfied until the pipe was completely clear and draining freely.
We then fitted the new Saniflo, reconnecting all pipework using new connectors and jubilee clips throughout. Every connection was checked before we restored the electrics at the fused spur.
The result
Once the system was live, we ran multiple flush tests and monitored pump pressure at each stage. The new macerator fired up cleanly, pumped waste away with strong, consistent pressure, and there were no signs of leaks at any of the connections — everything was dry and secure.
Before leaving, we walked the client through what had caused the original failure, how the new unit compared, and a few straightforward tips to help avoid a repeat down the line. They were delighted to have the toilet functioning again and commented on how differently — and how much more smoothly — the new pump sounded.
