The footprint of the house is 900 square feet. Less than half of standard for normal houses.
Exterior InstallationThe soil in Utah is normally dry.
There is a wet spring in near
nearby park. There is no pathway
gases from one hole.
We had to install a second suction
to get the levels down to below
2.7 pCi/L.
We the normal 501 fan the levels
was 5.7 and with a high performance
RN4 fan the levels got down to 4.4.
With a second hole the levels go to
to 1.1 pCi/L.
Hole number 1 West Side.Second hole on East Side
to get levels lower.
Over 99.5% of houses are taken care of two below 2.7 as the action level.
On previous slide show we reduced a 5a,250 with single fan!
