The Froet Drain® Roof Drain Froet Standard Drains Froet Flow Sensors Roof Drainage Business Rethought
• The Froet Drain® roof drain designed like no other roof drain • The industry’s original patented bi-functional roof drain and drain with vent
Froet Drain® roof drain • • • Cast Iron Fully cast one piece sump Powder coated finish Labor savings Roof penetration reduction Roof drainage simplified Most stoutly built roof drain on the market UPC and IPC Listed 25 Year Warranty Available
Superior Quality • Cast iron construction for all parts (no plastic) • Powder coat finish exceeds the industry standard • Superior quality will provide decades of service
Reduced Cost • Half of the roof penetrations • Less labor cost not just from the plumber but from multiple trades • $300. 00 to $500. 00 savings per roof drain location • Reduced project cost now and for life of building at every reroof • Durability prevents the need for drain replacement at reroof time. $1000. 00 to $2000. 00 possible cost per drain
Froet Advancements Largest bosses in the industry Anti-seize pre-applied to drain ring bolts 1 ½” drain ring bolts and 1 ½” tapped bosses Smooth sump no obstructions Integral gravel stop on drain ring (used to be an industry standard, what happened? ) • Lowest height free area drainage in the industry it starts ¼” above the membrane • Integrates with all roofing membranes and designs • • •
Roof Drainage • Location and elevation of overflow drain? • How often has your design not been correctly installed? • It’s always as you specified it with FROET
Flow Characteristics • We flow test our drains • Our published flow tests show superior flow with less head compared to standard drains and a primary system that reaches full capacity prior to overflow • This provides the designer with a proper functioning drainage system

P. M. flow rate when the overflow drain is elevated by 2”. This flow rate does not even meet the 1/8” slope requirement of 231 G. P. M. An overflow height of 3. 2” is required if this drain is used on a 1/8” slope rating. Greater height is required for higher flow ratings.

Is It Safe? • An overflow drain that runs all the time is nothing more than another primary drain. Which leaves you with no overflow protection. • A properly designed and built drainage system will work, an improperly built system may not.
Froet’s “MONGO” 8” Roof Drain Ø Froet is at the forefront of roof drain flow and durability Ø We offer a 25 year warranty, which no one else in the industry offers Ø The Mongo is the World’s largest 8” drain. Ø With its 3 rd party flow testing our roof drain is verified to flow 1700 GPM like no other drain Ø Competitions 15” 8” drain fails at 900 GPM (third party testing)
What You Need • • Quality products Information on how those products perform Simplified designs Easy to understand installation Cost savings A company that stands 100% behind its products A design that is minimally affected by roofing membrane manufacturers drain detail requirements
Why are only some of these drains ponding?
This is why! Sumped installation Flush installation If drain installation is such that it causes water to pond around the drain it will catch debris and cause drain blockage
Froet Primary drains Ø Are built to the same standard – exceeding requirements as our 100 C Bi-functional drains Ø The primary drain is designed to intergrade into any roofing system or design Ø So, when your project has a gravel stop perimeter or thru wall scupper for overflow protection, the Froet primary is the correct answer for your project
Green Roof? • We feel that the green roof box is the only safe means of installing a roof drain into a green roof. • It can be a 10, 000% increase in free area using a green roof box over a drain with the perforated S/S applied directly to the drain. • Perforated S/S requires 3 times the strainer free area to flow the same GPM.
Green Roof Box with Drainage Mat
Maintaining Flow • This blockage happened in 20 minutes under ideal conditions, what would happen on a actual roof?
Froet Black Box • • • Easy job site adjustability Fertilizer resistant Lower cost than stainless steel Many Lid options Even 10, 000 LBS rated lid Proven material for subsoil use
Froet Flow sensors Do you need to monitor for water and be notified or monitor for water and actuate a valve? If so then this is your answer.
Froet Flow sensors Low cost sensor 24/7/365 operation and notification when tied to a BMS Battery Back up to sustain operation during power outage Easy customized to your specific needs Overflow monitor, rainwater harvesting, Back flow preventer relieve valve monitor, water level monitor, etc… Ø If you need to sense water and turn valves this is your low cost option Ø Ø Ø
