Right Iv made a start on the speed fit droppers for this heating system. After knocked some plaster off i found the depth of the plaster was only 12mm. I was originally going to run the speedfit in 10mm trunking but found this sticking proud of plaster. I opted for some electrical sheathing and tacked this over it, works well I think. The pipes are now well below the plaster, only thing is really wanted to be able to pull the pipe out if it ever got damaged.[/list]
