Alarms are mandatory now on radon systems In MN where we can experience below zero temps for weeks. RE: Pipe size 3” or 4”, foam core, air flow makes no difference. They all usually end up with the classic snow cone at the top / exhaust end and a phone call from the homeowner. This is especially true on newer systems where the humidity leaving the pipe is far greater then on older systems. And installation of all interior systems is not a practical answer. So are we to tell the homeowner of an old 2 story home that your system will cost you 3 times the amount of $ so we can install a system alarm? 3 times the amount because of the disruption we will cause in your house to thread the pipe through walls and closets.
I and most mitigators in MN (see Randy’s original post) do not agree with setting off an alarm at 3:00am and waking up a homeowner because their system froze. A terrible idea to say the least and crippling to our businesses when the next day we will get run over by phone calls.
There are many low cost crm monitors available today that would be a great alternative to a blaring alarm. And I think most homeowners would agree.
A failed radon fan event does not need a blaring alarm event that instant. This individual standard needs more time to be thought through and more input from the ones being forced to install them.
After looking at the list of names that contributed to the ANSI/AARST SGM 2017 standard I find it troubling that the amount of mitigators on their are of a small percentage. And of the ones on the list - I would like to know how many actively install systems in a climate like ours.
I personally would also like to see a new method for including mitigatior’s in on decisions that effect our business’s like a system alarm. I would have love to have been a fly on the wall while the standards committee discussed such a controversial issue.
We are the back bone of the industry and I fell like we are getting pushed to the side while a small majority tries to insert themselves into what we built.
