System Features
- Waterproofing with synthetic membranes preventing structural leaks
- Constant, optimized static water pressures at all terminal outlets
- Sophisticated vertical venting stack layouts eliminating structural sewer gases
- SABIC and approved DIN standard PPR and PVC pipeline architectures
Common Installation Mistakes
- Conducting concrete casting over wet areas before double-testing waterproofing coats.
- Failing to install trap vents, allowing sewer gases to siphon back into occupied rooms.
- Using incorrect pitch slope angles in horizontal sewage runs, inviting solids sedimentation and clogging.
What We Need to Start
- Complete plumbing layout sheets including bathroom and mechanical room configurations
- Sizing parameters of primary water reservoirs
- Specified pipe brands (PPR/PVC) and valve standards
- Project structural drawings
