Information for some of you HI’s of Maine.
Besides what I have found and posted below, I heard today from my Plumbing Subcontractor Plumbing Foreman on the job, that the Plumbing code update taken a week ago, no longer admitts or legally approve Mechanical Vents installed in lieu of the regular vent through roof vents.
It appears this applies to Renovation, New Residential or Commercial Projects.
Have any of you Plumbing HI’s heard anything to this affect.??
