Check valves

“RTP” Sewer check flapper valve made of stainless steel with a reed seal, maintenance cover and connection Hole size into // outlets for PP-R, PVC flared pipes suitable for a flap fixing in the closed position through the hand lock with the safety cutoff preventing spontaneous closing.
Sewer check valve RTP-10 (grey) and RTP-110 (orange) is installed true-horizontal either in the basement (before transition of the internal pipe to the external) or in the outdoor sump. Thus, the sewer valve separates the indoor sewerage from the outdoor one. Inlet and Hole size into // outlet valve connections joint any PP-R/PVC flared pipe. If steel or cast-iron no-hub pipe is used for sewerage, transition from PP-R – PVC to cast Iron/steel shall be done.

 

Pipelines and fittings for the indoor sewerage

Nowadays the plastic pipes used for sewerage are applied habitually not occasionally. Their advantages result in better cost, as well as performance parameters versus the cast-iron pipes. Plastic sewer pipes meet all requirements of the modern indoor and outdoor sewerage.

The plastic sewer pipes are the most cost-effective solution for any real estate item. The assembling of such pipes requires no optional equipment; the transportation is costless due to the material lightweight. Reliability and long service life are the key advantages of the plastic pipes, which are resistant to a corrosive medium impact; sustain heavy mechanical loads. Besides the plastic pipes are completely leaktight and possess a high capacity.

The polypropylene pipes are considered the most perfect among all plastic sewer pipes. The polypropylene pipes are corrosion-resistant (unlike polyvinylchloride and polyethylene) and sustain high-temperatures (more 90°С) of effluents very well.

The polypropylene pipelines serve longer. Considering the minimum costs for maintenance their service life achieves at least 50 years. The undeniable benefits of the polypropylene pipes specify their choice during utilities systems arrangement
