In order for the Sinicon Comfort Plus sewer system to last as long as possible, the following points should be taken into account at the design and installation stage:
1. The sewer riser must be ventilated.
2. The riser connection must be one of the following types:
Direct outlet at angles of 87°-88.5° - this type is the most recommended, as it promotes air circulation, provides a low flow rate of wastewater and the lowest noise level.
Retraction at smaller angles, such as 45°, results in higher flow rates. This type of riser connection is not recommended as it restricts air circulation and increases noise levels.
Corner outlets with a reduced diameter should be avoided if possible - in this case, the risk of siphonage increases and the noise level increases.
3. Connection to horizontal pipeline
A 90° (87.3°) elbow should be avoided when the riser is transitioning to a horizontal pipeline - the use of such a elbow increases the risk of siphonage.
The use of two 15° bends in series reduces noise and excessive pressure, but this method of connection is best used only in cases of space constraints.
This option is the most recommended - a 2D length of pipe is installed between two 45° bends. This installation allows you to significantly reduce the pressure and noise level (at least 30% compared to the first two options).
4. If the horizontal pipeline is monolithic, the noise level is reduced by approximately 70-80%.
5. Pipes should be passed through interior partitions and floors in elastic sleeves (made of porous polyethylene or other elastic materials), which allow temperature movements and deformation of pipes without forming through cracks.
6. When installing the pipeline, only fasteners with a soundproof inner layer should be used.
As a rule, the insertion of noise-reduced fittings and pipes into a conventional sewer does not lead to a significant reduction in noise levels. That is, the entire pipeline system must initially be designed and installed as a system with increased sound insulation.
For maximum efficiency, it is necessary to use Comfort Plus pipes and fittings together with the new Comfort Plus clamps with increased sound insulation.
