Could the brad have lodged in the drainpipe?

[snowjim]

Hello,

I've been installing some moulding today and started thinking that one of the brads might be in the danger zone for the drain pipe (thick plastic pipe). Here is my estimated drawing



This is how it looks behind the wall where the studs are. You can see part of the OSB board on the left side, and behind this, the drain pipe is located at the bottom by the floor.



With the studs in place, it looks like this. The stud screw shown in the drawing, which is in the danger zone for the drainage, is the angled screw (down towards the floor) that holds the horizontal stud towards the left wall. Behind the OSB board on the left, I know that this stud screw ended up about 10 mm from the drainage, so it's not a risk.


This is how it looks with everything in place. The brad that might be in the danger zone is the lowest one holding the quarter round in place in the left corner.



The brads in the floor moulding shouldn't be a problem since I've used shorter brads than what was originally there.

The question is, could the brad at the bottom of the quarter round have lodged itself in the drainage? I would say I'm 90% sure that it's not an issue, but I'd love to hear what you think.

It can't be a particularly strong nail if you've used it for a quarter-round molding, so the risk is probably minimal that it went into the drainpipe. It's not so easy to drive a thin nail into a drainpipe even if that is your intention.

38 mm nail diagonally through 32 mm material (10 + 12 + 19) does not go through the sheet material. That is, it is not long enough to come out on the other side of the wall where the drainage pipe is. (Assuming it is nailed at a 45-degree angle. It requires a > 43 mm long nail to go through.)

It is a Ryobi 18V 16G(R18N16G-0) nail gun that shoots nails with a diameter of 1.6 mm and length of 19-65 mm.

You can adjust the power quite freely on the gun, and in this case, the nail went in about 1 mm below the surface of the quarter round.

So far, it has been able to drive nails into everything I've tried, including concrete. But sure, I haven't tested drainpipes (hopefully).

Hope you're right

38 mm brad nail diagonally through 32 mm material (10 + 12 + 19) does not go through the panel material. That is, it is not long enough to come out on the other side of the wall where the drainpipe is. (Assuming it is nailed at a 45-degree angle. A nail longer than 43 mm is needed to go through.)

A bit unsure where you get 10 mm from? The quarter round is not more than 10 and probably not much longer diagonally.

Anyway, I think like this: The material in the wall is OSB + Tongue and Groove Paneling, which gives us 22 mm. Then the quarter round, which is maybe 11 mm diagonally, so in total, we have 33 mm.

So, if we shot it straight in, the brad nail would stick out 38 - 33 = 5 mm. In this case, however, we are shooting it at almost a 45-degree angle, and if my calculation is correct, the diagonal is about 47 mm on a square with a side of 33 mm. So it should be fine, yes.

Even if it were to stick out a bit, we still have at least 10 mm extra in front of the drainpipe, since the framing screw that sits in the middle of the stud (about 22 mm) had about 10 mm to the pipe. So you could essentially say that vertically in the drawing, it is 10+12+10+22 = 54 mm.

Seems to have slipped on the keyboard. But have reasoned/calculated like you.
