removing a radiator

[TONY144]

do i need to have a shut off cap when removing a radiator with a thermostatic valve as unsure if by just turning valve off will stop flow of water to the radiator?

You need a cap, well I do on my Drayton tr4`s here

 

[TONY144]

mine are honeywell any idea where i might get a cap from as i dont want to have to drain system down

You just need a 1/2" cap and washer to go on the TRV outlet to rad connection. Alternatively a 15mm compression fitting blanking disc and nut will seal it.

you could just turn the thermostatic to 0. But if we get a frost it will probably open and water will **** out everywhere.

Should use a "decorators" cap

 

[TONY144]

what is a decorators cap please?

 

[chrishutt]

Tony, forget about decorators cap - read my post above.

This is a white plastic cap which replaces the thermostatic cartridge on the valve body. The big thermostat is removed by turning the threaded ring at its base anti-clockwise.

However Chrishutt's method will work as well, if not better.
