Hello

I've just had an old Armitage Shanks toilet replaced with a new Heritage
Bathrooms model.
The AS cistern had an upstanding pipe which allowed water to run out the
house in the event that the inlet valve failed - which it did a few times
over the years. The HB cistern has no such external overflow and as far as
I
can see, if I hold down the float it simply overflows over the top of the
cistern.

Is this correct, or am I missing something here?

Many Thanks
Des

Modern cisterns/syphons are designed to overflow into the pan. If yours is
not there is likely a problem.
