I'm putting in central heating (for the first time) in a flat and I am
thinking about what to do to enable me to drain it if ever the need
In other flats I have seen this accomplished by running a pipe through
an outside wall much like a cistern overflow.
However as I'm on the top floor if I take this approach I don't think
it will be possible for me to put the pipe at the required height
(i.e. below floor level) and then be able to reach it outside in order
to seal round the exit hole properly.
However someone in the past has gone to the trouble of doing this with
a cistern overflow, and what I am wondering is whether I can tap into
this for my heating drainage?
i.e. make a connection from the cistern overflow pipe to the central
heating loop via a gate valve.
Any issues with this? I think the overflow inlet in the cistern is
higher than my rads so I don't envisage the inlet turning into a
geyser when I open the valve. Also presuambly the water will take the
easier route out the end of the overflow pipe anyway.
Is this reasonable to assume?
Also any probs with the building regs?
If there is a better way (or standard way) of providing a drain point
please let me know.
Thanks for you advice.
