Werkstein
Pipe cleaning pump

The pipe cleaning pump from Werkstein made a very good impression in our test. The product offers a high-quality high-pressure drain cleaner. The pump is supplied with two different rubber adapters and can therefore also be used in hard-to-reach places . The product is supplied fully assembled and is ready for immediate use. Thanks to its high suction and pressure power, the pipe cleaning pump removes even the most stubborn blockages without the use of chemicals, regardless of whether they are in the toilet, sink, shower or bath. The material used is of high quality and very good workmanship. There are no unpolished edges or processing defects on the pump.

Advantages

✅Two rubber adapters
✅High suction and pressure force
✅German family business
✅Chemical-free application

Disadvantages

❌Instructions written in very small print
❌Requires some practice or technique

The first impression

Packaging and labeling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

The packaging of the pipe cleaning pump

The pipe cleaning pump from Werkstein arrived for our test in the typical shipping box. This was undamaged on arrival and could be opened without any tools.
The product packaging contained the pump with adjustable handle, two rubber adapters and the instructions for use. The packaging method optimally protects the product from external influences. As a result, product protection was fully guaranteed and the pipe cleaning pump was delivered in perfect condition. The packaging is also recyclable. In this respect, the product leaves a very good first impression. Neither the drain cleaner nor the packaging used was damaged.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The product packaging contained the pipe cleaning pump from Werkstein with an adjustable handle and two rubber adapters. The correct handling (including safety instructions) was described in the 5-language instructions for use. Contact information can be found on the product box. However, there is no customer hotline or e-mail address. Nevertheless, this is a very good way to send a product.

Pictograms on the pump

The pipe cleaning pump and the adjustable handle are made of high-quality ABS plastic. The handle can be easily loosened and adjusted to the right position without additional tools using a turning screw. The two adapters are made of rubber with a diameter of 9.5 cm each. They are 4.5 cm and 19 cm high respectively. There are pictograms on the pump itself that briefly show the correct handling. The materials used make a stable impression. We therefore expect a long service life.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test is the most relevant and therefore the most important. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

We enjoyed working with the pipe cleaning pump from Werkstein during the test. Attaching the rubber adapter is very tight, but if you put some washing-up liquid on the rubber adapter, you can pull it on relatively easily.
Placing it on the various drains is unusual and requires some practice. If you have previously worked with a simple rubber plunger, it takes some getting used to using the drain cleaner from Werkstein due to the size and bend of the pump. During the practical test, the suction and pressure mechanism worked without any further problems. There are two methods of clearing a blockage with the drain cleaning pump. The best known method is to place the adapter flush against the drain and pull the extendable handle upwards with a jerk. Another method is to fill the pump with water, place it flush on the drain and press the cylinder down with pressure. However, you must be careful to seal the drain well with the rubber adapter, otherwise it may splash.
Thanks to the high-quality material and simple packaging, it is also sustainable and saves resources.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.

*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.4 stars. The pipe cleaning pump is often criticized for being very expensive and not being a perfect fit for all drains. Many customers like the fact that the product works very well. In our practical test, we were able to confirm that the drain cleaning pump works well and that sealing the drain was sometimes really difficult to achieve.

Prices of up to €89 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as € 29. The pipe cleaning pump from Werkstein is currently in the upper price segment with a price of € 82. The price ratio is reasonable for the quality and scope of services offered.
