    Radon Control Methods

    Correct whole-house ventilation would eliminate this issue and resolve many others simultaneously for less money. Unfortunately, scare tactics have been used to embellish this issue.

    Radon Control Methods

    I am not disputing that radon is not really real. If I install a mitigation system with barriers, a fan, etc., and radon from a shower on the second floor comes out of the solution, the system will not remove it as designed. It will dissipate with passive ventilation. 2021 to present has led to...

    Radon Control Methods

    may, might, possibly,could have, etc. along with no certainties in code required mitigation to perform, is questionable at best. EPA's own documentation states that their findings are based upon uranium miners over forty who are exposed to high levels during an 8-hour shift. Taking a shower for...

    Clothes Washer DWV and IPC and UPC Comparison

    I believe you will find that the premise of the 2-inch stand pipe's maximum height and the connection to a three-inch or larger branch of stack is based upon the velocity of the discharge water, which causes siphonage of the trap and any other fixture in close proximity.

    Fuel gas code - distance between elbows

    Unfortunately, manufactures do not want to be overly prescriptive in there installation manuals unless it is critical to the performance. This manufacturer could have suggested 45 degrees instead of 90 degrees. A significant change in the HVAC industry was reducing the space from obstructions...

    Stacking the Deck at ICC Hearings

    CFM at register

    Look at ACCA manual D for duct design. Each room requires X amount of CFM to feed the occupied zone of the room. The air velocity will dictate the throw into the space and the CFM will control the volume.

    IRC M1503.3/4 and kitchen range exhaust vibration isolation

    Your exhaust temps at that connector with make up air is probably going to be around 100 degrees F if over 400 cfm or more. without makeup 140 ish. A good quality exhaust fan direct drive properly installed will have negligible vibration.

    Just the Concrete Encased Electrode

    It was available at the time of design, and if it was consequentially covered over it should be dug up.
