A New Dawn in DrainageLeaders in Siphonic Drainage

• Cost savings of 25 to 45% – Smaller Pipe Size• IPC 2015 compliant – All MIFAB® HYDROMAX® drains have ponding graphs and GPM of

the drain from testing to ASME A112.6.9• Ideal for primary & secondary overflow roof drainage.• Eliminate trenching under building floor.• Labor Savings

• Horizontal pipes installed FLAT, NO SLOPE, works in the BIM model and provides space savings.

• Less Ponding• Flexibility in routing – frees up building space.• Fewer downpipes with smaller diameters• Rainwater Management – easier routing to Retention Ponds or Rainwater Harvesting

IPC 2015 CodeSECTION 1105 - ROOF DRAINS1105.2 Roof drain flow rate. The published roof drain flow rate, based on the head of water above the roof drain, shall be used to size the storm drainage system in accordance with Section 1106. The flow rate used for sizing the storm drainage piping shall be based on the maximum anticipated ponding at the roof drain.

SECTION 1108 - SECONDARY (EMERGENCY) ROOF DRAINS1108.2 Separate systems required. Secondary roof drain systems shall have the end point of discharge separate from the primary system. Discharge shall be above grade in a location that would normally be observed by the building occupants or maintenance personnel.

A New Dawn in Drainage A New Dawn in DrainageLeaders in Siphonic DrainageIn order to correctly design a MIFAB® HYDROMAX® Siphonic roof drain system the following information is needed:

1. Design rainfall rate (inches per hour).2. Piping material: Schedule 40 solid wall PVC or Cast Iron (If PVC, specify sizes you have

access to).3. For quicker turnaround time (2-3 days).

Fully dimensioned Isometric drawing of each system with GPM’s at each drain location.4. For a standard turnaround time (no. of days dependent on complexity and size).

A. Plans showing or that can help us determine and fully dimension the following (In AutoCAD .DWG file format only. We can’t use .PDF files).

i. Catchment areas or the GPM’s per drain location (Roof Plans).ii. Preferred piping routes and discharge points (Floor Plans directly below roof.).iii. Elevation from drain to horizontal.iv. Elevation from horizontal to discharge.

5. Name, address, contact details including email address of Engineer of record or Design Build Contractor (Please include all contact info in order to set up access to HydroTechnic software).

6. Project title.7. Project address (City, State & Zip at minimum).8. Confirmation of below grade being designed to free flow or surcharge

(If surcharging, we need to know the height between the center of siphonic horizontal line at discharge to the manhole grate cover).

The provision of all the above requested information allows MIFAB® to assist with your siphonic roof drainage design.We will provide access to our MIFAB® HydroTechnicTM analytical design calculation software for the Engineer of Record, designer and contractor as directed by the EoR. Within HydroTechnic® you can access the hydraulic calculation, edit the design, print the design calculation report, BOM and drawing files. All dimensions, GPM’s, Routes, Pipe Materials, etc. should be verified by Engineer of Record.Please contact us at [email protected] at any time for assistance.

We offer full-time FREE design support. Our experience includes 1,000 Walmarts!www.hydromax.com
