My Problem Child has always been the drain in the kitchen. But he was as bad as this time never clogged. I've seen the craftsman has to build everything apart - horror! It helped not Pömpel and the bottle pipe cleaners (!!!) I had consumed in the past week so gradually, nothing has brought. Neither the Power Gel from advertising nor the granulate has helped. Now you have to know that the outflow is about a couple of corners before he disappears into the wall. The story of this spiral thus also does not work because even rum right, then left and then right .... But this pig is sensational! He arrived today and after two applications is all brand new. It runs better than ever before. The whole procedure has to cover and Read the manual lasted less than two minutes, and I'm so glad to be bound by the plumber once again by the shovel! I buy me in any case, a second copy for emergencies! Thumbs up and highly recommended !!!!!!
