Blocked Kitchen Sink?

Kitchen sinks get used constantly, so it is pretty common for them to block up. Grease, food scraps and soap build-up can coat the inside of the pipes and slowly close them off. Our plumbers use proper tools to clear the blockage fully, not just push it further down the line. We also check the fittings and pipework to make sure nothing else is going on. All work is completed to current BCP plumbing requirements.

Why Kitchen Sinks Block Up

A lot of things end up going down a kitchen sink without people realising. Oil, coffee grounds, rice, pasta and food scraps can all stick to the pipes and build up layer by layer. After a while the water cannot get through, so it drains slowly or stops moving completely. We look at the trap and the waste line, work out where the blockage has formed and clear it so the sink flows like it should.

How We Clear the Blockage

Depending on how bad the blockage is, we use different tools to get it moving again. Sometimes a small hand rod does the job. Other times a compact drain machine or a small jetter is needed to break down the build-up properly.
After the pipe is cleared, we run some water through the sink to make sure everything is flowing the way it should. If anything under the sink looks worn or cracked, we point it out and talk through the best way to sort it.

Stopping the Sink from Playing Up Again

Once the drain is running properly again, we take a quick look around to see what may have caused the issue in the first place. Sometimes the pipes are older and have tightened up inside over the years. Other times it is a mix of oils, scraps and things the sink was never meant to handle.
We can share a few easy habits that help keep the sink clear, like scraping plates before washing, keeping fats out of the drain and flushing it with hot water every now and then. Small changes can make a big difference.
