Drain Plugs

The ULVAShield system is completely water tight. Should at some point in the life of the system, the insulation become open to the atmosphere due to incomplete maintenance or mechanical damage then there is a risk of water ingress. Should this occur then there needs to be a path for this to escape.

ULVA recommends the installation of drainage ports for all hot systems which should be positioned at all changes of elevation and every three metres on straight pipe runs.

For open cell insulation ULVA recommends the use of its drainage patch, for closed cell insulation ULVA recommends the use of the NORSOK type plug.
