I am re doing my bathroom (still) and since my original leakage problem being because of varying reasons I have taken up all the floor and found that all the plumbing is plastic. I have read many differing opinions on using plastic and copper pipes. I live in a farm area and we do have rodent problems. Gien that and the age of the house I would not be surprised if I have them under the house seeing as there was a couple of dead bird carcasses found there.
Anyway, I have decided to replace the pipes in this area with copper (15mm) and my question is the hot water supply. There are no visible isolation or gate valve shut off valves on the pipework into this area. I have a radiator at one end of the bathroom area and a hot feed going to or coming from a radiator in the adjacent room via plastic pipe through the originial sandstone foundations.
The cold water feed is already isolated and the cold taps and cistern are empty. But will I have to drain the CH which is upstairs and at the furthest opposite point to this bathroom which is downstairs and at the extreme opposite gable end, or is there an easier way, I am thinking to locate the hot flow into the area and put an isolation valve on it at point of entry then I can get all the platic changed?
And is there any other considerations such as regs regarding pipe fixing to joists etc that I have to be aware of?
Thanks
