I am refitting my bathroom (ground floor) which will include a tiled wooden floor - the floorboards are being replaced by ply. I am replacing the old floor mounted towel rail for a new wall mounted one. I will be connecting to the existing central heating pipes under the floor and running the new pipes in the wall to where they will be connected to the new towel radiator. My concern is that being a bit old fashioned, I would prefer to have soldered joints under the floor because after they are covered by the flooring/tiles, they will be completely inaccessible and I think soldered joints would be more reliable than compression or push fit. The job would be considerably easier however if I could use plastic pipework because the existing CH pipes are iron and so I have to connect to where the existing connection is. The plastic pipes would not only allow a more flexible pipe run with far fewer joints but also I would not need to wrap them for where they run up in the wall. Am I right to prefer soldered joints or are the plastic push fit ones reliable enough for this job?
