I am trying to plan ahead a bit here, in the case of a condensing boiler when my current bermuda baxi fails, and the possibility that a new tarmac driveway gets done first. Some of my concerns apply which ever project gets done first.
Soooo.....if I did set a condensate soakaway, it would sit under the tarmac. Pedestrian traffic would require the >500mm horizontal run just prior to the soakaway to be also under the tarmac (to avoid a trip hazard).
My questions are....
1) Do the limestone chippings require replenishing or are there inspection requirements that would mean an access cover is needed (e.g. by the relevant RGI)?
2) How and where might I suitably cap the outdoor vertical condensate pipe (until needed)?
3) Apart from digging a pit (i.e. by the groundworks people for the driveway), is the rest of this a DIYable job?
4) Is any of this not permitted, or not a good idea for other reasons?
5) If a soakaway is not permitted under the driveway, is there a horizontal maximum distance limit?
Hopefully needless to say, other options are also being considered. Access to the foul drain would require complex external routing. Internal routing would involve tiled-floor bathrooms or solid-floor kitchens. A condensate pump would work but would require up-and-over pipework.
Thoughts welcome.
