Emergency help! Leaking pressure vessel!

[Ajbrox]

Hi my zilmet pressure vessel has rusted out on top of my boiler and sprung a major leak. I need some advice on what to do. I've shut the boiler down electrics side. The pressure vessel has been weeping for a good 90 mins now, do I need to turn mains water off too? Or open hot water taps to drain it quicker, any help much appreciated.

Close the cold water inlet isolator at the bottom of the boiler (5th from left) and open a tap to let the pressure off. Make sure you use a spanner, the slot is to show direction, not for turning it.

You mean this??

Yes, the one below the Pressure Reducing Valve. (The one with the grey bit).

Done it, worked a treat! Many thanks, big sweat on here!

To anyone else, those valves are OFF when the slot is at 90 degrees to the line of the pipe!

Since its an unvented cylinder and the blue vessel is the expansion one for the cylinder, so technically it should only be charged with air and fitted by someone holding the G3 qualification.

Contrary to some DIYers expectation, they do NOT come ready air pressured for connecting without setting by the installer.

Aj, just in case you were tempted ..... please don't try and replace the EV yourself, it is part of the unvented safety systems and must be repaired and signed off by a qualified engineer. Get it serviced at the same time
