Roebic K570: For Opening Drainage Systems Septic Tanks

Roebic K570 can prevent problems in the soil infiltration network and solve blockages in the drainage field more quickly.

The wastewater from a septic tank is sometimes discharged to a drainage field through a series of
perforated pipes. Sludge build-up can clog these perforated pipes and cause the wastewater to stink, among other things. Blocked or slow drain fields are the main reason for septic system failure. When drain fields fail, grey water rises to the surface. This stagnant water indicates a problem in the system. Roebic K570 quickly tackles these problems.

New! Even more concentrated and 40% less plastic
This product is now even more concentrated! A 250 ml bottle is suitable for a septic tank of no less than 1,500 litres. So you do not compromise on the efficacy of the product, but you do save on the use of plastic. A bottle contains 40% less plastic. Good for your septic tank and for the environment.

Roebic K570 is also suitable to solve, for example, a blockage at a pocket pit or infiltration pit.

What is Roebic K570 suitable for?

Roebic K570 can prevent problems in the infiltration network at septic tanks, infiltration pits and pocket pits, for example, and can solve blockages in the drainage area more quickly. K570 opens the soil infiltration system from the septic tank or sump towards the drainage area.

K570 prevents system problems with patented bacteria that break down proteins, starch and other food-related organic waste.

How do I use Roebic K570?

For best results, use Roebic K570 in the evening before going to bed.

1. Shake well before use. Flush the entire contents of the package down the toilet or directly into the bag well or septic tank.

2. Flush 2 times.

3. Repeat dosage every 2 weeks if problems persist.

Restrict use of toilets, sinks and washing machines etc. for 24 hours after treatment.

When the problems have been eliminated and the drainage system water is clear again, it is recommended to add Roebic K37 or Roebic K47  to the tank as a preventive maintenance product.

What is the difference between K570 Leach and Drain Field Opener and the K57 Septic Tank Emergency Aid?

Roebic K570 is specially formulated to treat the leach / drain area and open the infiltration network that comes after the septic tank.

Roebic K57 is a problem-solving emergency product to vigorously treat the septic tank when you are already experiencing a blockage or slow-running system.

Treating the tank alone will not prevent sludge from accumulating in the main line or prevent build-up or blockages in the drainfield/drainage system.

Can I use Roebic K570 just after the septic tank has been emptied?

We recommend using Roebic K570 on a septic tank that has been in use for a few months and has not been emptied recently. The pipe that goes from the septic tank to the drainfield is at the top of the tank and not at the bottom. Therefore, your septic tank must be at a normal level for this product to have a chance to work.

What can affect the functioning of K570?

In the case of a septic tank or small waste water treatment system, be careful of cleaning products containing chlorine! These can seriously disrupt the biology in the tank.

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

Is the packaging of K570 recyclable?

Yes, the packaging is recyclable. We have chosen to provide more and more products with new environmentally 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.

I had an obvious clog between soakaway and septic tank. Completely inaccessible to a human. This solved the problem almost instantly.
