A blocked drain can result in a sink full of dirty water that takes ages to vanish down the plug hole. There are many drain unblockers on the market, so let’s look at some and when they work.
Do they work?
Drains are often blocked when substances such as fat, grease, and food waste are poured down the sink. Generally, drain unblockers work well on these small blockages.
If they don’t work, you may have a more serious problem. This may be a large blockage or an issue such as tree roots blocking your drains. In this case, you should seek professional advice from a company that can carry out a CCTV drain survey to identify the problem.
To find a company that offers this service, use a relevant internet search; for example, ‘CCTV drain survey Wolverhampton’ will return results such as https://www.wilkinson-env.co.uk/drainage-services-cctv-surveys-midlands/cctv-drain-surveys/wolverhampton/.
Best drain unblockers
Drain unblockers can be found in most supermarkets. These include:
- Mr Muscle Power Gel Drain Unblocker. One of the best options, it works quickly, potentially unblocking the drain in as little as five minutes.
- Sainsbury’s Sink & Plughole Unblocker and Waitrose Essential Drain Unblocker. Effective supermarket own-brand drain unblockers, these work in about 15 minutes.
- Cillit Bang Drain Odour Eliminator & Unblocker Gel. Effective, although not as fast-acting at around 30 minutes. You should also check to see whether it is OK to use it if you have a septic tank.
- Soda crystals. Cost-effective and also work in about 30 minutes; however, they require more preparation than the other options.
