Mine did that.

There was a piece of insulation or other gunk blocking the outlet.

Inserting a pokey thing caused the entire contents of the tank to
discharge.

Owain

Pokey thing gone to top of list.

When you use the pokey thing, and assuming it does its job, have a *large*
vessel into which the water can safely drain during the time (which will
seem like several centuries!) before you can screw the drain cock closed.
And then attach your hosepipe and drain it into the bath / kitchen sink /
flower beds.

Hope you didn't have to manhandle the *full* cylinder through 90 degrees to
access the drain cock (it was round the *back* - duh!). When the immersion
heater element of mine broke and needed replacing, I had to empty the
cylinder to remove the horizontal element near the bottom of the tank. And
the drain was on the back so after unscrewing the cold inlet and the hot
outlet, I had to "walk" the cylinder round on the baulks of wood that it was
resting on. Luckily I got a lot more than a trickle from the cock (oooh,
Matronnnnnnnn!), so no pokey thing was needed ;-)

I had to Google what a fortic tank was. I've only seen one before and that
was in my first house. For some reason the builders chose not to put a
header tank in the loft or to make it a mains-fed cylinder. Cost, I suppose.
