    Was at house today with a pellet insert running upstairs in the living room and a pellet stove running in the basement. I set up the Magnehelic gauge and it was pushing .80 WC in the basement and nearly 2.31 WC upstairs. YIKES! I asked the customer if her or him (the husband) was irritable or augmentative all the time and the answer was yes...

    So is the life of folks living in a "sick house" constantly under negative pressure....OAKS are important.

    Hi Scott

    augmentative? Do you mean argumentative?

    It is interesting about the pressure. Where did you connect the guage? What should the normal reading be?

    The normal reading should be very close to zero.
    Scott, a woman is always going to answer that question yes.

    What?!?! Did they have a while house fan running and all the windows and doors closed? That seems excessive. Certainly coming from more than a dinky little pellet stove exhaust fan with no oak.

    At least...
    Edit. Maybe an ERU and the outside air fan is not running?

    Just for a reference, when doing a blower door test on a house, they usually pressurize to 50 pascals which equals 0.2 inH20.
    And
    0.8 inH20 = 199 pascals
    2.31 inH20 = 575 pascals
