hi,
I have a plastic soil pipe internal to the house exiting through the roof through flashing into an external soil vent projecting around a metre above the roof. The pipe is reachable in the loft, albeit a bit of a headroom squeeze as its near to the external wall. The external vent is right slap bang in the middle of the optimal place for solar panels on the south roof of the house, so it needs to go..
I figure I have two options, both involve sawing off the pipe level with the loft floor and then:
1. fit an push-fit internal AAV to it level with the room ceiling / loft floor. will be reachable from inside loft for service. loft is never going to get converted (not a usable space).
2. use flexi's, elbows and extension pipe work to redirect the vent to the north roof and refit there, exiting through the north roof as a similar type vent to now , or a vented tile.
option 1 is pretty easy and diy-able. solar installers will just remove the vent , make good the roof and re-tile leaving a unbroken roof prior to their install.
the AAV would be around 2.1 meters above the nearest input to the soil pipe (a bathroom with toilet, shower and bath).
option 2 more fiddly/messy (air pipe run across the loft) and requires a new roof opening to be made. solar installers could probably do it but more cost. is there a reduced diameter pipe I could sensibly (by which I mean, size reducers exist) use if doing this as its simply dry air?
any reasons not to do 1?
thanks
