Rainwater Outlets

Rainwater outlets for flat roof refurbishment and new build projects

ProDrain Rainwater Outlets are a range of versatile units that are available in a large range of sizes for new build and refurbishment applications.

The large flange provides excellent coverage and is available in various waterproofing membranes to suit the relevant roof covering. This flange is factory bonded to the spigot of the outlet which ensures a reliable watertight connection. The spigot is manufactured from high quality, corrosion resistant stainless steel and the 'O' ring provides an excellent seal whilst still allowing for movement. A variety of leafguards are available.
