Hi,
I think we have a few plumbers here and I'd really appreciate it if someone could help.
I currently have a tiler in doing the floor downstairs and also half height in the WC, as well as fitting a towel radiator. He's Italian and speaks broken English but is doing a very good job. The basin is out and the pipes are capped (no shut off valves) and the bog is also out.
Tomorrow he'll be tiling the walls of the WC and fitting the towel radiator. He asked me this morning about draining the central heating system. I wasn't quite sure if he was asking me how to or perhaps more likely where from. It's a new build (I think it's a closed system? I have a filling loop to repressurise) and I'm fairly certain I've seen one of the house builder's plumbers draining it down from the top of the boiler when a leaky locksheild needed replacing but I might be mistaken.
However having read a few websites it seems the process is to shut off the boiler (on a fused spur) and then find the radiator with a drain valve and let all the water out. Then when you've done whatever it was you planned on doing, refill the system via the filling loop, switch the boiler back on and check each radiator to bleed air initially (starting downstairs) and also again when warm, and then top the system up again to account for any lost pressure from bleeding.
Does this sound right? It may be he just wanted me to point out where the drain valve was but always handy to know.
Thanks,
Ben
