• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

What I have fixed today

What were your radon levels? Our's fluctuate between 18 to 34. A level not to worry about.

Here the government recommendation is to mitigate if levels are above 4 pCi/L. Ours were about 8 when it was measured in May. The previous owners installed the system at our request as a condition of sale. We also have an ERV which I have set to keep a slight positive air pressure inside the house which should also reduce any infiltration. I will be re-testing the levels this weekend.
 
Could you not dispense with the fan altogether? The pipe would work like a chimney or a stench pipe, the wind at roof level would be enough to evacuate the pipe, would it not.?

Probably that wouldn't work. I say that because the system comes with a simple U-tube manometer. If I turn off the fan the manometer equalizes: negligible difference in atmospheric pressure. With the fan it pulls 6 inches of water. There are smaller and presumably quieter fans but this is the one the installers recommended. I don't know how they choose what size to use.
