boiler feed & vent pipes

[mike]

Hi

system:- fully pumped H/W and heating

Due to builing works I want to move my H/W cylinder form upstairs, t downstairs next to the boiler. I will then be left with the situatio that the existing system cold feed and open vent pipes will be in th return pipe and not the feed pipe as they are now, will this cause me problem? I can't see why it should but then I'm not an expert.

Thanks for any help

Mik

I can't quote chapter and verse but I'm sure this would be wrong. The boiler installation manual is likely to be quite explicit about this.

The system may be converted to sealed?
