Very good with an old 18-year-old Karcher pressure washer series 7, of course, I did a good job, unclogged the house drain, clogged pipes for many years

It does what it promises! I used it to unclog a balcony drain that I had a problem with, and it worked perfectly. I would like it to be a little more flexible for the corners in the pipes inside

It was used on a Kärcher K3 pressure washer. I unclogged the kitchen-central drain of a single-family home. It took me more time, of course, but the job was done. Completely satisfied with the purchase, which was made from a store in Thessaloniki.

It works properly and smoothly, it is of good quality. Satisfactory results on drainage pipes. It was not needed for any serious reason, but for maintenance and cleaning.

Quite good and reliable. For household use it's ok - cleaning pipes etc - at regular intervals

It works exactly as described in the product description. I applied it to three drainage pipes and have had no problems so far. It dissolves and breaks down fats from soap scum into smaller and manageable pieces, where a regular steel pipe would simply puncture and pass through. If someone has a pressure washer, it is a necessary accessory. You will not regret it.

It was used in a Bosch Aquatak 135 pressure washer with an adapter for Karcher accessories. I unclogged a drain with a drain auger for which a professional was charging 80 €. It took me more time, of course, but the job was done. I preferred Karcher because the equivalent Bosch product has double the price. Completely satisfied with the purchase.
