I just want to check that I'm doing the correct thing.
I'm having solar panels fitted and the soil stack is problematic owing to it casting a shadow over some of the PV panels.
To resolve this, I'm thinking that I can cut the soil stack short in the loft and put an air admittance valve on it. Then, I repair the felt and tile the gap ( placing new tile(s) under the solar panels and putting old tile(s) with their patina where the soil stack was ).
I have read that there's a rule of 5 for mains ventilation. Of the two houses either side of me, 3 have their soil stacks as normal and one ( immediately adjacent to me ) probably has an air admittance valve ( no soil stack poking through the roof ). So, from the rule of 5, I seem to be ok.
Is this OK? Have I got wrong the idea or missed something?
Thanks.
