Cesspool First Aid Kit: the solution for blocked cesspools + restarting

Do you have a cesspool with a serious blockage and are you bothered by stench, among other things?
There is a way to get it working again: Cesspool First Aid Kit is the product that can help. This package is specially composed of 2 products: one product for dealing with the problem and one product for (preventive) maintenance afterwards.

How does Cesspool First Aid Kit work?

Cesspool First Aid Kit is specially designed for households that suffer from severe cesspool blockages and want to restart it. It contains two 100% organic products: Roebic K 57 and K 47.

Roebic K57 is suitable for problem solving in case of overloaded full cesspools/clogged cesspools. Roebic K57 provides a concentrated attack on blocked areas, allowing the cesspool to return to a usable state. After solving the problems with the cesspool, (preventive) maintenance of your cesspool can be started.

Roebic K47 is the product which is suitable for preventive maintenance of the cesspit. Roebic K47 is composed of a special mix of various bacterial cultures which ensure that the waste from a system to which only toilets are connected (black water) is broken down more quickly. By speeding up this process, the chance of odours, blockages and overflows is reduced.

How do I use Cesspool First Aid Kit?

  • Use Roebic K57

For best results use Roebic K57 in the evening before going to bed

1. Shake well before use. Flush the entire contents of the package down the toilet.

2. Use 946 m/l per 1500 litres tank capacity.

3. Repeat the dosage after 3 to 4 weeks if the problems have not been resolved.

Note: Depending on the condition of the system, it is sometimes necessary to treat several times with K-57. You should wait a period of about three to four weeks between treatments. If the system is running well after one treatment of the K-57, you can apply the K-47 the following month to maintain your septic tank.

  • Use Roebic K47:

1. For best results, use Roebic K47 in the evening before going to bed.

2. Shake well before use. Flush the entire contents of the package down the toilet.

3. Repeat the dosage twice a year or as required.

What’s in Cesspool First Aid Kit?

  • 2 bottles of K57
  • 2 bottles of K47

This kit is suitable for tanks up to 3000 litres.

Is the Cesspool First Aid Kit a preventive package?

Yes, it is. Roebic K57 and K47 are preventive working products and are 100% organic. They are safe for your skin and all types of pipes.

What can affect the working of Cesspool First Aid Kit?

In the case of a septic tank, cesspit or WTP, be careful of cleaning agents containing chlorine! These can seriously disrupt the biology in the tank.

If there are broken pipes or serious technical defects, this kit will probably only be partially effective.

Is the packaging recyclable?

Yes, the packaging is recyclable. We have chosen to provide more and more products with a new environmentally aware sustainable packaging. Therefore the bottle may differ from the original picture above. Our new bottles are made of 100% recycled plastic. Of course, the content and functioning of the product is the same as in the original packaging.

To protect the products from damage, we use – if necessary – packing paper as filling material in our packages. The packing paper is made of 100% recycled paper.

Will you help us recycle? You can recycle the packaging with the old paper and plastic waste so that it can be reused.
