I wanted to try and get some advice on the best way to pass 15mm plastic pipes through under floorboards.
I have plumbed in two manifolds - upstairs & downstairs and need to connect 5 rads to each one. The manifolds are central in the house and most pipe runs will be about 3m upstairs and about 4m downstairs, although there are a couple of longer runs to small rads. Pipe to the manifolds is 22mm and to the rads will be 15mm plastic.
Upstairs I have 9inch joists so plan to drill 30mm holes in the centre of the joists and feed the pipe through. This sounds simple but on my first one I had some trouble I think because of misaligned holes. Any other tips - vaseline perhaps?
Downstairs I have a suspended floor with a foot and half cavity under floorboards. The joists are only 4 inches. I was planning to insulate the pipes and then try and pass them under the floor and clip them to the underside of the joists using builders band. I have two problems though. One is that perpendicular to the joists there are lattice brick wall supports which I need to thread the pipe through. Also there is an area of parquet flooring I hope not to have to lift up. I was thinking of perhaps trying to get a wire through and pull the pipe through, or using a hook on the end of a broom handle to help. I was wondering if there are some easier ways of doing this.
I planned to use 25mm wall pipe lagging for the downstairs but am worried that the size of this will make it more difficult to pass through. Would 19mm or 13mm be easier?
I did try and get a couple of quotes from plumbers to hang and connect up the 10 rads but both refused to take on the work and only wanted to fit the boiler. They said they had never used manifolds for anything other than under floor heating – made me worried I was doing something wrong. From discussions with the plumber’s merchant and searching online it seemed that this kind of thing was standard practice now.
Does anyone who’s done this kind of thing before have an idea of how long it will take to hang and connect 10 rads? And given the fact that I have done all the other work do you think this is why a plumber doesn't want anything to do with piping in the rads?
Many thanks for any info you can let me have - its much appreciated.
