The 1605 and 1005 Full-Bore Siphonic Roof Drains promote the
principal of full-bore flow within the engineered siphonic roof drainage
piping system. These drains use Siphonic action created by a patented
internal baffle to have superior volume and velocity performance compared to
traditional roof drainage.
Other than the baffle, a siphonic roof drain has the same features as a
traditional roof drain including a drain body, flashing ring, dome strainer
and fastening hardware.
| Features |
Benefits |
| 1) Siphonic action is independent of pipe pitch or gradient |
No pitch is required, thus interior overhead space can be reduced; Building height may be reduced saving on construction costs |
| 2) The point of rainwater discharge for the roof can be at a single corner |
Below slab installation costs are reduced due to fewer points of discharge; Extensive, costly trenching for external storm drain piping may be reduced |
| 3) Siphonic roof drainage systems with single discharge points reduce rainwater harvesting costs |
Aids in achieving LEED’s points to qualify for green building projects |
| 4) The siphonic drain removes air from the water creating a full bore which results in smaller pipe diameters |
Smaller and lighter pipe diameters and pipe hangers reduce material and labor costs |
| 5) Stack and horizontal pipe locations are highly flexible |
The lack of drainage piping pitch provides for maximum use of interior open space |
| 6) High velocity full bore flows |
Higher velocities promote self cleaning |
*A siphonic roof drainage system can achieve 40% to 50% savings over conventional roof drainage. The actual savings will depend on the specific roof size, rainfall amount and overall drainage layout. For more information, please see the Siphonic Roof Drain Presentation or

Design Software for Siphonic Roof Systems:
- We are please to offer the siphonic design software, SiphoniTec®, developed by Rainwater Management Systems (RMS), our partner in siphonic roof drains. This software greatly aids in the design of siphonic piping systems that will be compatible with Jay R. Smith Mfg. Co.® siphonic roof drains.
SiphoniTec® is an easy to use and is beneficial in roof drain piping system design for large roof applications. It is suitable for all siphonic system
project requirements. It was designed by an engineer for engineers.
Some of the features include:
(1)
Calculation details and imbalance tabs,
(2) MS Excel report features,
(3) GUI tree design, and
(4) the ability to load and remove multiple projects.

Online Training Course for Siphonic Roof Systems:
- Online Training Courses for Siphonic Roof Drains from www.pdhonline.org
Available on www.phdonline.org are the Siphonic Roof Drain Systems and the SiphoniTec® Sizing Software continuing education (CE) courses. These courses were developed by the writer of the ASPE and the ASME standards.
These courses can be downloaded in a PDF format and participants earn hours towards a PE license or CPD renewal. Both courses require a fee and successful completion of a quiz in order to receive a “Certificate of Completion.”
To take either course go to www.phdonline.org, then enter “M256’ for the Siphonic Roof Drain Systems course and “M268” for the SiphoniTec® Sizing Software course.
