Stuck drain cock on DHW
 

I just tentatively had a go at the drain cock, mainy to test my booster
pump in the inverted position - unpressurised water is hard to find in me
hovel - and found it's jammed fast, as far as I can see with a mirror the
suare bit is rounded, and I can't really get to it because it's 1/2" from a
side wall on about half a ton of brassware left over from the war.

That's a great start to the project.

My only thought is perhaps I can siphon out with a hose in the top after
I've drained the loft tank.

I don't want 114 litres of water over me floors, anyone help me on
minimising the flood?

The traditional DIY way of emptying your system is by accidentally
drilling through a pipe

can't you got some mole grips on it ?

I havent got any - I'll see if I can borrow some, but I've got some pretty
good force on it with a small wrench before it started slipping off and
it's _very_ tight

Unscrew the hor draw-off pipe at the top of the cylinder. Insert a 15mm
copper pipe that reaches the bottom. Have a hose pipe clipped to the copper
pipe. Now suck and siphon the water out.

If you are that desperate, try one of those washing machine taps with the
punch hole style fittings. You can attach a long hose to those with the
right bits.

You could try applying some heat to it too - the bottom line is, like
England being 2-1 down with 2 minutes to play, you have nothing to lose,
although you might be successful

Maxie, it is nice to see you back. Did you have a great time getting your
rocks off? Fabulous.

Do you mean the sort that clamp on to pipes? trouble is the only pipe is
22mm, and I think the pipe ines are 15mm.

Or is there a sort that will cut int the tank itself.

(I hope to siphon it out, but just in case I can't move the other
connections, though I guess I can cut the outlet pipe and stuff a hose
in... I need to cover all me bases)

Thanks to all contributors - I never managed to unscrew it, but got the H/W
pipe off and siphoned it out through the hole.

When I got the tank out I found the drain cock had the squarw bit buried
about halfway int the body, and the bit left poking out well rounded, so I
was never in with much of a chance.

Bit of easy C/H pipework improving to do, then more queries as I put the
new cylinder in....
