Septic Tank First Aid Kit

Do you have a septic tank with serious odour problems, and/or a septic system with a blockage and you want to get it working again? Then Septic Tank First Aid Kit is the product you need. This kit is specially composed with 2 products: one product to deal with the problem and one product for the (preventive) maintenance afterwards.

Contents:

  • 2 bottles K57
  • 2 bottles of K37 – extra concentrated

How does Septic Tank First Aid Kit work?

Septic Tank First Aid Kit is especially meant for households that are suffering from serious clogging of the septic tank and want to restart it. It contains two 100% organic products: Roebic K 57 and K 37.

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

Roebic K37 is the product that is suitable for preventive maintenance of the septic tank. These bacterial cultures accelerate the decomposition of toilet waste in the septic tank. Stench, blockages and toilet overflows are (again) prevented by this. These very specific bacteria reduce the smell, but also prevent the tank from filling up quickly.

This package is still suitable for a tank up to 3,000 litres.

How to use Septic Tank 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 1 bottle 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 K-57, you can apply K-37 the following month for maintenance of your septic tank.

  • Use Roebic K37

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

2. Use 1 bottle per 1500 litres tank capacity per year.

3. Repeat the dosage as described at least once a year.

What is in the Septic Tank First Aid Kit?

  • 2 bottles of K57
  • 2 bottles of K37

This kit is suitable for tanks up to 3000 litres.

Is Septic Tank First Aid a preventive package?

Yes, it is. Roebic K 57 and K 37 are preventive working products and are 100% biological. They are safe for your skin and all types of pipes.

What can affect the functioning of Septic Tank First Aid Kit?

In case of a septic tank or IBA, be careful with cleaning products containing chlorine! These can seriously disturb 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 conscious 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.

Suffering inexplicable sewer gas stench in our home … on mains and our utility company, various plumbers snd Drain specialists are baffled. we’re trying Drain Line Cleaner as an almost last resort. 1 x 4 doses so far and waiting for our 2nd delivery. Hoping for a result and will post further. Howver a 3 week lead time on amazon and c.£25 per bottle is almost as stinging as the stench.
Answer: Thank you for your review! I hope our K97 has helped in the meantime. If not, you are always welcome to contact us by email, mentioning your order number, so we can take a look at your situation!
