What is a retrofit drain?

What is a retrofit drain?

Retrofit roof drains are designed to replace existing drains in reroofing applications. Installed from the roof surface, Retrofit drains are engineered to be installed without removing the existing plumbing or fixture while providing a watertight connection to the roof system and the existing plumbing.

What is a wall scupper?

Description: Scuppers are used to provide an outlet through parapet walls or gravel stops on flat and built-up roofs to allow drainage of excess water. They can be used in conjunction with gutters and downspouts to divert the flow to the desired location.

How do you install a retrofit drain?

Installing Your Retrofit Roof Drain

1. Remove the broken drain from the drain pipe.
2. Attach the seal to the roof drain accordingly to prevent water leakage and other debris from entering the drain pipe.
3. Insert the retrofit roof drain into the existing drain pipe and tighten the protective seal.

What is a scupper on a roof?

This drainage system looks like an opening in the parapet or wall of your flat commercial roof. Some scuppers have a simple spout that pours water down the side of your building, while others are connected to downspouts that send the water directly to the ground level.

Is a scupper a drain?

Roof scuppers are not the same as roof drains. Roof drains channel water through the deck of the roof into a piping system that carries water away, while a scupper allows water to drain through an opening in the side of the roof edge.

How do scupper drains work?

In short, a scupper is a detail that provides drainage to a roof system by allowing the water runoff from the roof to exit the roof through a metal edge, parapet wall or through the deck into a downspout or leader not run through the interior of the building.

How much does it cost to install a roof drain?

Installing drainage runs most homeowners between $1,961 and $6,015 with an average cost of $3,982. Small, simpler solutions could be as low as $500 and more complicated projects could get as expensive as $18,000.

How does a flat roof drain?

Gutters are the most commonly used drainage system when it comes to flat roofs. Just like the gutters installed on sloped roofs, these marvels catch rainwater and divert it into a downspout, which carries it away from the foundation.

What is the difference between olyflow retrodrains and u-flow seals?

U-Flow Seals exceed the ANSI/SPRI RD1 standard for back flow prevention. OlyFlow RetroDrains are designed to replace existing drains in re-roofing applications. U-Flow seals help to provide a watertight connection to the existing drain leader.

Why do I need overflow roof drains?

With the advent of sloped roof decks and tapered insulations, it has also become necessary to include Overflow Roof Drains to relieve dangerous overloading of the structural system caused by heavy ponding water

What is the purpose of a U-flow seal?

U-Flow seals help to provide a watertight connection to the existing drain leader. Due to manufacturing variances and jobsite inconsistencies, these figures are to be used as a guideline and are not a guaranteed fit in “tight” situations.

What type of screwdriver is used to install U-flow seals?

U-Flow Screwdrivers are used to install U-Flow Seals. The long 317.5 mm shaft ensures ease of reach when tightening the U-Flow Seal connection screws, and all U-Flow screwdrivers come with a loss prevention bar. U-Flow Seals exceed the ANSI/SPRI RD1 standard for back flow prevention.
