IKO AV Vertical Rainwater Outlets

Application

Suitable for connection to continuous waterproofing systems using single ply membranes, mastic asphalt, high performance built-up felt and wet-applied systems.

Description

Vertical rainwater outlets, are designed for use with flat roof structures using either in-situ cast concrete, timber or lightweight metal deck construction.

AV Vertical Spigot or Threaded Outlets:

Provide anti-vortex performance within an economic range of general purpose outlets. Designed for connection to downpipes on a gravity system.

- Vertical Spigot Outlet - Domical Grate:

Suitable for direct connection to cast iron pipework to BS EN 877 and BS 416, high density polyethylene (HDPE) pipework and polyvinyl chloride (PVC) 'O'-ring socketed pipe to BS 4514 and BS EN 1329-1 (AV300, AV400 and AV600 outlets only). Consult literature for details.

- Vertical Threaded Outlet - Domical Grate:

Has a female socket with parallel thread to BS EN 10226-1 for direct connection to threaded tube conforming with BS EN 10226-1. This tube is supplied with BS EN 10255 taper male thread which ensures a completely watertight joint when screwed home into the socket outlet.

Threaded outlets are recommended where a connection to the outlet occurs within the thickness of a concrete slab. In such cases, a threaded connection will create a completely gastight seal within the slab. The outlet can be connected to socketed and socketless cast iron pipework, high density polyethylene (HDPE) pipework and polyvinyl chloride (PVC) pipework by means of the spigot adaptor with appropriate IKO coupling.

Flat grate:

For use if the outlet occurs in an area which is subject to pedestrian traffic. These grates are also designed for use with IKO Modulock Drainage System, where concealed rainwater outlets are used. Loading rating: 1.5 tonnes.

Terrace grate:

Designed for installation in terrace tiles or brick paviours. They should be used in connection with grate extension pieces which raise the grate to the level of the paved surface. The radius slots in the grate allow for movement through 90°, permitting adjustment to suit surrounding paving prior to final tightening. Loading rating: 1.5 tonnes.

Accessories:

- Grate extension pieces:

  • For applications where it is necessary to raise the level of the grate above the body of the outlet, such as in inverted roof construction.
  • Will accept domical grates and terrace grates but not standard flat grates.
  • The extension pieces can be cut down if necessary to suit the thickness of paving or tiles. This can be done easily on site with a hacksaw, or, if required, extension pieces can be trimmed prior to delivery.

- Threaded spigot adaptors:

  • The threaded spigot adaptor has been designed to facilitate the connection of IKO Roof AV and Detail threaded aluminium rainwater outlets to all types of pipe systems and provides an alternative to using a short length of steel gas tube to BS EN 10255 in the case of cast iron socketed or socketless systems.
  • Manufactured from acrylonitrile butadiene styrene (ABS) plastic, and supplied in 400 mm lengths with a taper thread externally at one end to BS EN 10226-1 and chamfered at the other end to BS 4514 and BS EN 1329-1 spigot dimensions. Sizes are available to suit 50, 75, 100 and 150 mm nominal bore pipework.
  • The adaptor is screwed into the base of the outlet using a polytetrafluoroethylene (PTFE) tape or silicone sealant to obtain a gas-tight seal. The spigot end of the adaptor can then be connected to the pipe socket. If necessary, the length of the spigot end of the adaptor can be reduced by cutting as required with a fine toothed saw.

Applications:

Suitable for connection to continuous waterproofing systems using single ply membranes, mastic asphalt, high performance built-up felt and wet-applied systems.
