Here Are Some Useful Roof Drain Installation Tips

  1. The sump receiver does not lower your roof drain below the deck and may cause it to sit slightly higher. This is not a problem if the roofing is sufficiently thick, as in the case of an insulated roof. (or 1″ or more). If not, you run the risk of causing heavy ponding rainwater.
  2. Pressure test and flow test the entire installation for at least 15 minutes after installation.
