Client Reviews

ARRON COOPER, PE, VICE PRESIDENT, HENDERSON ENGINEERS INC. (BENTONVILLE, AR)

“Henderson Engineers, Inc. has designed HydroMax siphonic roof drain systems for hundreds of buildings in the United States using the HydroTechnic calculation program. HydroTechnic is an excellent tool that equips the mechanical designer with an understanding of siphonic system operation and provides an excellent graphical interface.”

ENGINEERING FIRM (ATLANTA, GA)

“Just wanted to let you all know that on our weekly conference call today the contractor said that the price for the siphonic system came in “somewhere between $201,000 & $235,000 less” than the conventional system they had originally priced.”

DAN ZIMMERMAN, MECHANICAL MANAGER, THE WALDINGER CORPORATION (OMAHA, NE)

“We have been utilizing the MIFAB siphonic roof drain products and design services for several years. The HydroTechnic’s design team is very helpful and willing to assist us in meeting the expectations of our customers. The siphonic roof drain system is a great value engineering offer that we can offer to our customers and clients. The siphonic design is a proven cost savings over traditional gravity system designs.”

ED YELIN, CPD, ERDMAN ANTHONY & ASSOCIATES (ROCHESTER, NY)

“I have been a regular user of MIFAB’s HydroTechnic software since 2017. The program’s intuitive user interface, coupled with the world-class support we receive from MIFAB, consistently results in fully optimized system designs with significant cost and performance benefits.”

GENAINE BAILEY, PD, OCI ASSOCIATES, INC. (ORLANDO, FL)

“Working with HydroMax and MIFAB, is incredibly easy and convenient. You can layout your siphonic piping design as you would traditionally, send your routing to them, and they will size the system for you! They are an email or phone call away from getting me the answers I need when I need them, and they train the contractors prior to installation. I would recommend HydroMax and MIFAB Siphonic Roof Drains systems for all sorts of projects.”

FRANK WESTHOFF, PE, OWNER, WESTHOFF ENGINEERING (PLANO, TX)

“We chose to do a siphonic drainage system on a recent warehouse project because the client wanted all piping to be above the bottom of the roof joists. The MIFAB team were very helpful with the design process and were very easy to work with.”
