Hi. I need to replace the central heating pump. There are isolation valves on either side so when I went and closed one of the valves it started leaking. I have the leak controlled now but I need to replace the valve (and I might as well replace the other one while I'm at it). I followed the copper piping looking for another isolation valve but there's none before it turns into old gun barrell piping. I can't figure out how to turn off the water (or isolate the valve) in order to replace the isolation valve. Any suggestions? Thanks.
