Do you see the pressure relief valve? Why is it open? Unless you know the answer to this, I suggest you ponder the following:

You can do an awful lot of damage with a pressurised HW cylinder. Your one contains over a fifth of a ton of potentially boiling (superheated!) water. That's obviously potentially lethal. Qualified plumbers need special certification to be allowed to play with these.

So, as geoff says, get a man in.

I replied to this the first time you posted it yesterday... you need to work out which valve is defective and why, and then replace it.
