The ReadySump™ RetroDrain® is a pre-fabricated roof drain sump and integrated OMG retrofit drain in one easy-to-install product for enhanced rooftop productivity. The ReadySump is designed to eliminate the labor-intensive, multi-step process of field fabricating a drain sump, and re-working or installing a drain on TPO membrane roofs.
Features & Benefits
- Installs in about one-third the amount of time vs. making a roof drain sump and installing or re-working a drain for maximum productivity.
- Heavy duty cast aluminum strainer dome features OMG’s exclusive Vortex Breaker Technology which helps improve flow performance and gets water and excess weight off the roof faster.
- TPO sumps are made with durable closed cell polyurethane that provides an average R-Value of 6.5, compatible with most TPO membranes, and UV stable for long-term roof performance.
- ReadySumps feature a standard 9.75-inch drain stem and the proven U-Flow Mechanical Seal, which exceeds the ANSI/SPRI RD1 Standard for a secure, watertight connection.
- ReadySumps are flashed at the highest point of the sump and not around the drain for improved rooftop quality.
ReadySumps are pre-fabricated TPO drain sumps with integrated OMG retrofit roof drain in one easy-to-install product for enhanced rooftop productivity.
ReadySumps are designed to eliminate the labor-intensive, multi-step process of field fabricating a drain sump, and installing or re-working the drains.
A standard 9.75-inch drain stem accommodates most field conditions and can be shortened if necessary. The proven U-Flow Mechanical Seal, which exceeds the ANSI/SPRI RD1 Standard, can provide a secure, watertight connection to the existing drain leader.
The following is accurate for all ReadySumps:
Drain Body: .187 TPO formed thermoplastic
Dimension: 4- x 4-ft. Perimeter with 2-in. tall perimeter edge
Body Cavity: Closed cell polyurethane. Average R-Value is 6.5
Drain Seal: Proven U-Flow mechanical seal.
Strainer Dome: Cast aluminum, yellow powder-coated with integrated Vortex Breaker and Twist-Lock seal
Drain System: Standard 9.75-inch length.
Drain Sizes: 3-, 4-, 5-, and 6-inches for most applications.
Slope: 1:12-inches (nominal)
ANSI/SPRI RD-1 – is a national performance standard for retrofit roof drains which requires the seal to hold a 10-ft. column of water for 24 hours without leaking.

|TEST STANDARD||TEST DESCRIPTION||MEASUREMENT/TARGET VALUE||LOCATION|
|ASTM E108 Spread of Flame Test||A fire-test-response standard that is used to evaluate roof coverings in both residential and commercial roofing applications for materials used on combustible or noncombustible desks. Measures how quickly flame will spread once the roof assembly catches fire.||The ReadySump meets or exceeds the requirements of a Class A fire rated roof assembly.||Third Party|
|ASTM D6978 Weathering & Visual Inspection||Advanced weathering simulates years of UV and heat exposure as well as wet dry cycling. This specification covers flexible sheet made from thermoplastic polyolefin (TPO) as the principal polymer, intended for use in single-ply roofing membranes exposed to the weather.||The ReadySump meets or exceeds the requirements of the ASTM D6878 Visual Inspection.||Third Party|
|ASTM D412 Tensile Strength and Elongation at Break||A common standard for determining tensile properties of vulcanized (thermoset) rubber and thermoplastic elastomers. Sump drain material was tested post weathering.||The ReadySump material tensile strength =2480 (psi); Elongation at Break = (46%)||Third Party|
|UL2218 Impact Testing||Impact resistance testing for the evaluation of low slope roofing systems. The test evaluates the effect of impact from a steel ball at locations on the assembly selected to be most vulnerable, such as (but not limited to) edges, corners, unsupported sections and joints||The ReadySump meets or exceeds the requirements of the UL2218 impact in 40 drop locations. Drain impacted with and without membrane attached as well as in both flat and material creased areas.||Third Party|
|ASPE/IAPMO?ANSI Z1034-2015 Flow testing||Test Method for Evaluating Roof Drain Performance and conducted in accordance with Section 4.1 "Vertical-Pipe Roof-Drain Test."||See Flow Rates Table||Third Party|
|ANSI/SPRI RD1||A national performance standard for retrofit roof drains that covers many design considerations inclusive a leak test. Drain bodies with backflow seals shall withstand a continuous test pressure under the equivalent of a 10-foot head of water or 4.33 lbf/in.2 (30 kPa) above the elevation of the backflow seals without any visible leakage after 24 hours. Laboratory test method RF-1 shall be used to test the backflow seals.||The ReadySump meets or exceeds the standard.||In House|
|Membrane Weld Study||OMG Performed extensive testing that included welding new membrane to new sump material, tested immediately; welding new membrane to new sump material aged together and tested; welded new membrane to aged sump material and tested.||The ReadySump material is compatible and welds to all major brands of commercially available TPO roofing membranes.||In House|
