hi, My sister has converted her garage into a dining room and needs to fit a radiator in there. The closest pipe work is located in an upstairs bedroom which is 10 mm pipe connecting to a radiator which connected from 15mm pipework. my question is in two parts, can i feed the new rad from 10mm that is connected to upstairs rad or does it have to be connected from 15mm pipe and secondly can i used 15mm pipe to new rad whichever pipe I connect from,regards ste
