DRY siphon with silicone membrane
TUBE-TUBE installation
Dry siphon without water to replace traditional siphons and save space in the facilities, this type of siphon can be installed both vertically and horizontally.
Inside it has a silicone membrane which acts as a non-return valve, opening when water passes through and then closing when the water has stopped, at the same time preventing odors and the passage of insects.
- BSP Female Inlet Nut x Universal Compression Outlet
- The membrane opens under water pressure to allow discharge to flow freely and then closes to form a seal to prevent odor or sewer gas from entering the building.
- Can be placed horizontally or vertically
- It can be installed in a facility where a check valve may be beneficial to the plumbing installation.
- No water seal, so it can never dry out through evaporation or lack of use of a device as the membrane remains sealed
- Not recommended for use with shower trays unless there is access for maintenance
