Wherever the drainage system is under sunk, we consider the following parameters:
- Noise levels
- Smell
- Maintenance
- Cost
Silent pipes are preferred to control noise level and a MultiTrap to prevent smell issues.
Drawbacks:
- Silent pipes are costlier
- Height riser pasted connection to the trap results in leakage over time
- The Trap seal cap can be removed
Superior option developed by Urja
As the client wanted an economic option, we designed an under-sunk drainage system where there’s only one silent pipe for the main header and connected all the type B pipes to it. This solves the noise challenge but also economizes the design. We also added an Ultra-silent MultiTrap with a 50 mm water seal with a fixed cap. And since the HDPE and UPVC connections are not practical in pasting, we proposed O-ring fitted connections for the MultiTrap and SWR pipe.
Advantages:
- Saves cost
- No smell because of added water seal and a fixed cap
- Reduced noise level
