EPDM Drain Outlets are used to connect EPDM membrane to internal rain water drains.

• The slightly conical shape enables fast and simple installation in rain water drains. The roof outlet has a smooth flange to improve adhesion to the EPDM membranes and has two rings on the shank which act as a drain trap between the outlet and the rain water drain. The resilience of the material used in its construction guarentees a long term seal.

• The shank in the upper section has a series of internal serrations which ensure that the leaf-excluder or gravel-excluder is fixed tightly to the connector.

• Resistant to deterioration by the sun, ozone and other agents or chemicals normally found in the atmosphere. They have excellent flexibility even at low temperatures. The mechanical properties are maintained in the long term.

• Must be used with Quickprime Plus & Elevate Flashform.

More information can be found in the installation guides, but to summarise:

• Ensure the EPDM is bonded first as required, & neatly cut the hole to the drain.

• Apply some Bond & Seal Sealant to the reverse of the drain face & slide in position, compressing the sealant.

• Mechanically fix with washes & fasteners as required.

• Cut your 18'' Quickseam Flashing to size, allowing 75mm overlap onto the EPDM on all sides, as well as the full face of the drain. Place in position & chalk around the edge.

• Using your Quickscrub Holder & Fleece, apply Quickprime Plus within the chalked area, plus an extra 10mm.

• Once touch-dry & tacky, apply the quickseam flashing, starting at one side, peeling the tape & smoothing into position as you go - taking care not to stretch or create air pockets.

• Work into position with Silicone Rubber Roller & Penny Roller. Apply shallow bead of Lap Sealant to edges if required. 

• Cut out the drain hole carefully, taking care not to damage the internal drain beneath.

  • Can the EPDM Drain be fitted under the EPDM?
    The EPDM drain must sit on top of your EPDM, with the necessary hole cut out. You then flash over the drain face with your Quickseam Flashing Items.
  • Can I cut the Internal Drain to size?
    The internal drain can be cut only if absolutely necessary. For example, if the drain feed is very close to a wall, you may need to trim the face to allow the fit. You must be very thorough with subsequent flashing though to provided the necessary watertight seal.
  • Can I seal the EPDM Internal Drain with Silicone?
    No, you can stick it down in place with a high quality sealant, though we advise a mechanical fixing. You must use seal the drain to the EPDM with the necessary Elevate Quickseam Flashing items.

Notes on the delivery of Elevate EPDM:

If you order EPDM with your items, the rubber will be delivered rolled up for ease of transport. As a result there may be some fold creases and wrinkles - this is normal. To remedy this, the EPDM should be laid to rest, or settle, for a minimum of 1 hour. In colder temperatures, the light use of a heat gun (not a naked flame) can be used to settle the rubber. Don't overheat or touch directly.

Starting your project:

We advise not booking in or arranging an installation team to begin works before the goods have been delivered & inspected. Delays or order mistakes are rare, but can happen. We can't be liable for any costs as a result from delayed or incorrect delivery or items.
