I am proposing to change my bathroom radiator (installed 1970) for a towel rail, which will be in 15mm. Examination under the floor shows the flow end being piped with 1/2 inch copper; I anticipate no problem connecting here. The return end is piped in 1/2 inch BSP pipe (OD 21mm), with a female BSP connector on the end which reduces to 1/2 inch copper. It will not be easy to connect to the 1/2 inch copper as it immediately goes into a double bend (poorly done) and up above floorlevel.
Ideally, I would like to cut the 1/2 inch BSP pipe (and shorten it as the towel rail is narrower than the radiator) and fit a compression fitting round it which allows reduction to 15mm copper. However, I have failed to identify such a fitting, so first question is are they available? Alternatively, can one use a 22mm brass fitting?
Suggestions already made from a plumber is to cut the 1/2 inch BSP pipe and rethread, so that a new BSP fitting can be used to reduce to 15mm. I would have to hire the tools and access under the floor is poor.
Or try to remove the existing BSP fitting and replace it. This would involve a rather circuitous route for the 15mm copper but it would be possible. However, what are the chances of removing the fitting after nealy 40 years?
Any suggestions welcome.
