What search term should I be using to find a *decorators blanking plug* for my CH system?



Decorators arrived unexpectedly yesterday and wanted two radiators off the walls. The TRVs seemed to be holding on the frost setting until



3.00am when the whole house resounded to a rapid 100Hz water hammer!

I had tried the 5 pence piece trick but they don't fit 20 year old Myson valves!

1/2" blanking nut?

The leaflet supplied with mine refers to the "manual commissioning cap"

Ah - the items that the installers throw away!

!! It would be a long while before I thought of that:-)

Screwfix have 5 1/2" blank nuts at St. Albans.

That's not a nice way to describe their staff...

with candle wax around it? funny old things water hammer. The flats where we have our studio suddenly started on which made the whole block sound like it was under attack from a very large hammer drill. Eventually traced to a valve in a shower room on the ground floor. Brian

Not sure I'd trust an old TRV to be totally leak free.

I'd use a stop end which should screw into the output of the valve and give a seal.

Other way for just papering is to slacken the rad and hinge it down flat, supporting it on wood blocks etc.

Only three now. Interesting location. Screwfix, Toolsatan, Wickes, Homebase. All within the distance I used to be able to throw a cricket ball.

OK Job done. The Mysons have yet to leak but they jam as well as anything else.
