Aerocyl plus unvented cylinder

[bobron]

Hi Guys, just after some advice if someone could help.

I have a Aerocyl plus unvented cylinder in my house, Heat pump external (no gas)
I have a steady flow of cold water though the pressure relief tundish. Its constant as far as I can tell.
Going to call out a plumber tomorrow but in the meantime should I be shutting off the water and electric to it? Or should I leave it as is. Not sure how long its been doing this as me airing cupboard is full of crap and see or hear the tundish.

Any advice would be welcome

Cheers

I'd be tempted to shut it off. Make sure the plumber is G3 qualified
