Product range RV SYSTEM ®

Bottoms of inspection wells and street inlets, manufactured from polypropylene, introducing homogenous wall and high ring stiffness, excellent in heat resistance of up to 95°C. This is the basis for building inspection wells for home sewage connections and yard inlets as parts of rain drainage systems.

Maximal operating temperatures can be found in individua catalogues of waste and sewage systems and sealing.

Sealing Area of application- temperatures
SBR (at the producer /within the range of Work) cca. -50°C up to +100°C
EPDM cca. -50°C up to +150°C
NBR (can be ordered separately) cca. -30°C up to +100°C

SBR Improved abrasion resistance and age resistance, good resistance against operating liquids
EPDM Excellent fastness to abrasion, ageing and fastness to most of operating liquids
NBR Versatile material. Sealing for contact with mineral oil or fuels. Poor resistance against ozone and weather resistance.

Our KG-System (PVC)® products are manufactured in classes SN 4 and SN 8, KG 2000 . Polypropylene® products are manufactured in the class SN 8 and MAGNACOR in the class SN8.

The sealing of systems BL, DD and Euro L Spezial are resistant against water with maximal volume of chlorine 0,6 mg/l.

„Placement in the area of ground water is possible only if it is ensured that the embankment material is not dislocated and shifted (e.g. embedding the fine gravel in concrete to the filtration layer)".

„During works in the area of ground water it is necessary to ensure that the bearing/supporting layer of placement does not contain water during the construction work implementation"

„The zone of pipework must be protected against each predictable change of bearing capacity, stability or the bed when such change can be a result of the ground water action for example".

Be so kind and contact us if you have doubts about suitability of the sewage piping placement. In such case we will carry out an analysis of structure.

We have the “leak tightness at external over-pressure” test record of the manufacturer of sealing rings at our disposal. The manufacturer is the firm M.O.L. and the test record is dated 14th July 2004). The test was conducted against the external pressure action in the height of 0,5 bar (5m of water column).

No, it cannot. 
Among other things, this provision serves for elimination of the backwater formation and formation of retained amount inside the system.

No, it is not. It is not allowed to take the piping of the rain water and sewage water inside the building together. The piping can be directed into the joint piping only outside the buildings (near the connecting channel on the boundary of the property).

The exception will become valid if the border development is concerned. In such case it is permissible that the rain water piping and sewage water piping is drained together inside the building.

The pipes with slide-in sleeves / couplings are usually placed in such manner that the sharp end is in direction of flowing. The sharp end is sliding into the sleeve / coupling.

The quote from Manual of plastic pipes (4th issue, paragraph 3.4.4 Construction of the sewage water channels and piping, page 463)

Thus the piping placement in direction of flowing is clearly defined.
