How are metered roof drains used?
Metered roof drains are installed on flat roof systems. Their primary purpose is to allow a small amount of water to drain through them, and allow for water to pool on a roof top. This pooling allows for the sewage treatment plants not to be overwhelmed by the rain water. The metered roof drains must be spaced 50 feet from the roof edge and 100 feet from another metered roof drain. Each metered roof drain has 4 weirs built into its body. By removing weirs you can control the amount of water that will drain. The more weirs removed the faster the roof will drain. The roof must be engineered to hold the weight of the pooling water. More information can be found on the web sites from the manufacturers of metered roof drains. Zurn, Mifab etc.
