I want to remove a couple of radiators to decorate - I have done it many times and the (Twinfast) valve always leaks a little - but I put a tray under to collect the drips. However, this time we are getting a new, light carpet! I want to blank off the valve outlet where the radiator attaches to reduce the risks.
Question - what do I need to blank off the valve?
If they're like mine, the thread on the open part of the valve (which normally attaches to the radiator tail) is probably 3/4" BSP. I have some plastic caps with 3/4" BSP threads which protected the inlets to a washing machine during transit. I cut corks to fit the valves, and use the caps to hold them in. I think you can get brass blanking cap-nuts which do the same job - and you could use rubber washers rather than corks inside them.
