Rad valves

[dancinplumba]

Really what? I'm struggling to keep my eyes open.. What am I saying?

arent rad tappings 1/2" not 3/4" ?

 

[PlumbBobBob]

were the valves leaking?

yes they are, you then have either 3/4 or 1/2 connections to the valve

Sometimes. Just buy a rad spanner Radiator Spanner | NoLinkingToThis

If it's the tails with the flange that use a larger nut, then they are usually an Allen key to remove, though some old types have a couple of lumps inside. A set of grips on the edge of the flange on the tail will remove them if they're on with ptfe (& you are scrapping them). Some have a O ring seal as well as a taper & will perish. Replace whole lot.

Most rads & valves are 1/2" but some rads & valves are 3/4".

Ok thank you. I will try find my Radiator Allen key.

If you're not using the tail again then you may be able to loosen it by inserting one jaw of your water pump pliers in there and turning it that way.

Or if you have the valve off as well, tighten the valve back on and spanner on the valve will turn the tail out.

I find if the the "Allen key" bit has been worn out 2 big flat head screwdrivers shoved in can do the trick or as mentioned before tighten the valve back on
