I need to remove a radiator for decorating purposes. I am OK with the
'normal' valves and locksheilds, but this one is a TVR, the only one in
the house don't ask why I don't know, probably the baby's room of the
previous occupier. The system is a sealed system, filling loop on the
boiler etc. How do I isolate this radiator in order to remove it? I
have visions of the valve opening during the night and flooding the
house! In this warmer weather will turning it down to the frost marking
Do you have a "cap" for the TRV? Probably not if you didn't fit it....
This will close the valve right down! I don't know if the Frost setting in
summer will be sufficient.
I removed a rad (to send back to Screwfix) and left just the TRV on the
closed position - it emptied the system down to no pressure and boiler
didn't come on on coldest night of the year when I wasn't around = unchuffed
Sorry I can't be more positive - but I can warn you against leaving the TRV
unattanded for any period of time.
Here's the thread where I got pointed in the direction of the "cap" - says
you might be ok if there's no "cold snap":
When you buy the valves they come with a cap to turn them off, just
remove the thermostatic head and use this cap. I guess you don’t
have the required cap, so you could try at the plumber’s
merchants and ask there if they have one. You will need the make of
valve, as they are all different. Try posting the make on here perhaps
some kind person will send you one. I would not try just turning it
down, that sounds like a possible disaster in the offering, other wise
drain the system down. Rob
Yes it should be but you can always put a temporary cap on the outlet pipe once
the rad is off. About a quid from your local plumb centre.
