Recommended! Good products and personal advice
At home we suffered from a sewer smell and the cause was the shower well. We had already used various products, so there was absolutely no unblocking. But the air did not disappear. That is why we phoned and enquired. I had the Anti Sewer Air Package 1 in mind, but because of the personal advice I was advised K27. That saved me half the money and it helped perfectly. So thank you very much.

Problems with septic tank solved in no time!
We have been living in Spain since January and have a septic tank there. The tank had to be emptied and then reactivated. This went perfectly with the BioSeptic+. We use it every week and as soon as there is a pipe ‘clogged’, we throw the powder into that pipe. After one day, the line then runs again. We have now ordered for the 2nd time. We still have stock, but our family takes this for us. That saves on shipping costs 😉

Excellent service and excellent products
Fast delivery and I have been using your equipment for a septic tank and a ‘grease pit’ for two years now. The water that is discharged is crystal clear and does not smell.
Sometimes there is a smell from the drainpipe, which is also connected to the same drain as the tanks. Now I’m going to try to put stuff in there for the pipes, I don’t know if that works yet (it’s a holiday home and I haven’t been there for a while).
