Kitchen sink backing up? It's almost always fat and food waste.
Kitchen sinks block for a very consistent reason: fat, oil and food waste cool and harden inside the pipe, narrowing it a little more every time you wash up, until eventually nothing gets through. Shop-bought drain unblockers rarely shift it properly and can make a proper clear harder.
We clear the blockage mechanically rather than relying on chemicals, so the pipe is genuinely open again rather than just temporarily softened.
Fat and food waste blockages turn up just as often in the commercial units near Garston as they do in kitchens across Liverpool's residential terraces, though the pipework — and the fix — can look very different between the two. We clear what's actually blocking the line, domestic or commercial.
We'd generally say don't — it rarely clears a proper fat blockage fully, and it makes the job messier and slower for whoever clears it after, including us.
It can, if fat keeps going down the drain. Scraping pans into the bin rather than the sink is the single biggest thing that prevents it recurring.
