I can see no sensible way of routing a gravity condensate drain from our
proposed boiler location into an existing drain. (The location would be
in a 'boiler cupboard' where the existing floor standing boiler would be
replaced by a wall mounted unit.) Whichever route would cut across a
doorway.

There appear to be two options a) a soakaway and b) a condensate pump.

For us, even routing pumped condensate would be awkward. So I am taken
with the idea of a soakaway. I have looked up the basic details on the
ODPM site and we appear fine. But in newsgroup archives I noticed that
the Environment Agency apparently have rules that inhibit use of such
soakaways in some places. Does anyone have more information on this
issue? Are there any general guidelines as to the areas in which they
are or are not acceptable? (Our soil is a heavy clay which is one
concern.) Do we have to do anything special to gain approval?

I imagine that I should ring building control but was hoping to make at
least outline plans over the weekend.
