Who remembers the TV commercial where the domestic worker pours ¼ bottle of Toilet Duck into the toilet?
One of our clients who has a Scarab system, complained that his system regularly stopped working, and the water comes out pretty stinky. On inspection, we found the bacteria had died inside the plant, likely to have be caused by household disinfectants. We queried the source of contamination, and the client was very happy to show us his battery of household cleaners. On the front of the bottle, it clearly stated "kills 99% Germs" and on the back, in small print "safe for septic tanks". I pointed out this contradiction, and said client claimed that the manufactures would never tell lies.
The days of punishing our water are over. This abuse has to stop. The good news is that Scarab does offer our own range of eco-friendly household cleaning products (see here), which are a lot more kinder to your system. Every single product is carefully selected from a wide range of ingredients, suited to the task it's asked to complete.
These speciality products are, on average, not more expensive than what you might find in the supermarkets, BUT they are not harmful to the water system. This is a Scarab branded product, but it is suitable for all systems.
And about the TV commercial - I wrote to the manufactures telling them that they are killing our systems. I never did get a reply, but the adverts suddenly stopped.
