Best Drain Unblockers in the UK

Occasionally our drains and sewage systems will be blocked by fat or waste. Normally, the water slowly drains or no longer runs and sooner or later, we’re all faced with blocked drains and we need the right products to unblock them.

Are you constantly tired of unblocking your bathroom drains? Have you tried and failed at the baking soda and vinegar tricks? MZR Drainage can not only help you by visiting you, but we also offer cost-effective solutions to help you along the way. Select the best solution for you from an incredible array of products on our shortlist and easily maintain your drains.

Pro-Kleen Super Strength Formula

The team over at Pro-Kleen clam that their Super Strength Formula is up to 20 times stronger than any standard drainage opener. We do not know how right this is, but we can certainly say it does the job.

As we know, grease and hair dissolve fully, however severe the drain blocking may be. You can use it on bathroom sinks and clogged drains. It is actually suitable for almost all plumbing, from plastic and PVC, through to metal and copper.

The manufacturers recommend that 250ml of their solution should be an ample amount to unblock your drainage and plumbing. You should then leave it for a minimum of one to three hours, but preferably overnight if you can. Rinse the drain with plenty of warm water afterwards.

The product leaves mixed impressions when it comes to efficiency. On one hand, if you use the required 250ml per treatment, you get 12 treatments out of the box, giving you the best value for money. On the other hand, some of the toughest blocks can require over 250ml, so the cost-effectiveness of the solution is more difficult to measure.

Putting aside the practical price point, it doesn’t matter how tough the blockage is, this drain unblocker can clear them all.

According to Amazon, this product is rated 4 out of 5 stars from around 250 reviews.

HG Classic

As the title suggests, HG Classic Liquid Drain Unblocker offers the classic and straight to the point product. It’s a classic cleaner and it’s made its way onto the shortlist because of that.

When all is said and done, the speed and practicality of a classic formula is a main factor. Of course, on these fronts, the product is superb.

You just have to pour 300ml down the drain for a regular block, which usually takes about 30 minutes to work. You can then rinse it with either hot or cold water. As far as slow draining pipes are concerned, it is better to apply the same amount of solution to warm water, let it sit overnight and rinse with warm water the next day.

The product has some benefits over its subpar competitors. In terms of practicality, you don’t need to dilute the product, decreasing the chances of splashback. When it is poured into the kitchen sink, it does not spill or splash leaving your hands nice and clean. However, one thing we would advise against, is using this product on aluminium or zinc piping.

According to Amazon, this product is rated 4 out of 5 stars from around 380 reviews.

Mr. Muscle Max Gel

The Mr. Muscle brand has been advertised as the ultimate gel unblocker and doesn’t play around. It’s not only because of how effective it is, but also how convenient and practical the difference between this solution and its subset counterparts is. With other standard drain cleaners, you usually have to wait for hours or leave it overnight for them to work properly.

With Mr. Muscle, all you have to do is add the solution, wait five minutes and run hot water down the drain. When required, you can repeat, but this is rarely necessary because it usually removes the blockage from drainage pipes fairly rapidly first time round.

This fast-acting unblocker will dissolve any blockage and any unpleasant odours will be eliminated. A quick-acting unblocker eliminates grunge and hair in a single dose and quickly clears the worst blockages.

This drain cleaner can be used with sinks, kitchens and toilets for the bathroom. Whether this Mr. Muscle Gel is used on rubber, PVC, metal or a sewage pipe, it doesn’t matter.

Mr. Muscle Max Gel Unblocker is one of the best and strongest cleaners on the market and is MZR approved!

According to Amazon, this product is rated 4 out of 5 stars from around 100 reviews.

Scotch Corporation Heavy Duty Liquid Drainer

This is best described as a cost-effective treatment for all blockages on household drains by the Scotch Corporation.

Place two cups into the drain steadily, allow it to sit for an hour or two and then rinse it with hot water. Although you may not have to, for serious blockages, it is best if you leave the solution to sit overnight. That said, if the blockage is closer to the bottom of the drain, it can take longer than one night to remove the obstacle.

The formula is definitely the best part of this product. The non-acid formula guarantees all piping and drainage is safe, but we advise not to use this solution on waste disposal drainage because the non-stainless steel can become damaged. We also recommend to not use this product on toilets either, because it can potentially lead to it overflowing, causing safety issues.

All in all, with its moderate price, solid caustic formula and convenient packaging, this heavy-duty drainage cleaner from Scotch Corporation makes an enticing case.

According to Amazon, this product is rated 3.5 out of 5 stars from around 550 reviews.
