not sure what kind of study you are referring to, i will read it tonight, but plumbers don't test new pipes with water in the p trap. they have to plug the ends and leave the air sitting for a period of time to measure the loss. that's why i hate reading studies that purport to address things i am very familiar with when they do it wrong. thanx for the info without a paywall.

i was hoping you had something to show me i was wrong. usually that's how it's done when correcting folks. i make the statement, and it's right unless you can show me it's wrong. if it worked as you said, then everybody is always right. hell, even my college professors knew that. i was right and argued with them unless they could show me i was wrong. it happened a lot, and i learned a lot. most important thing i learned was not to change my position unless proven wrong, then accept the error, learn from it, and move on. i'm not concerned with your ideas, unless you can prove them. i have my own ideas, no room for any of yours. facts are always welcome. have a great day.

so you say. without proof, i'm right. i'll gladly agree that i am mistaken if you have a link. i'd actually like to know, but not nearly enough that i'll go look for it. have to be at work soon.

sounds like unnecessary work to me. when they test the pipes they put air in and leave it. when they are used, the p traps have water in them, preventing any gas from entering the house. otherwise, they don't work and you get sewer gas inside, and that is fairly noticeable. after the original air that was used for testing is replace, the harmful gasses are gone, usually way before anyone moves in. it's a non-issue.

maybe not, but the magnetic record found in core samples can tell us. from what i've read on the subject, they do know that wandering happens both immediately before and after the shift. last time i checked i think it said it happened in the span of a century or two.

i didn't say it was or wasn't, i said if op was using a drywall anchor there something else was gonna happen. i don't know if they'll work, i use the correct things whenever i can. op also said tapcons were hard to come by down there. yeah, i read them all.

did you read the other comment? must've missed the part where it said "pls correct me if I'm wrong"...

also, if op is using a drywall anchor in brick, something else is gonna happen regardless of the tolerances.
