leaking tundish

[ejm]

We have unvented heating system, the overflow is blocked with ice and we have been getting slight leak at tundish. Will obviously unblock the overflow pipe but was wondering if there is anything further we should be doing .
I have read about recharging the system? was worried there may be more to the problem than the blocked overflow.

Cheers

You seem to have a leak on a safety valve.

Depending on which one it probably needs to be dealt with by a qualified person.

I hope the tundish will never freeze up! If it did then you could have an explosion!
