Great way to start you third thousand posts thanks John b.

John you sly fox, were you a mason in your past life? ha. ha.

I can’t choose correctly with what you posted. I’ll explain when you give the answer.



Great. I’m always willing to learn. At this point and time I only see one correct answer, but a man with your experience will surely enlighten me.

Can’t wait and am looking forward to the additional information that you have.

Mums the word, right Marcel :wink:

Remember…This question is relevant to Brick Veneer Walls and not solid load bearing brick walls.

I am with Marcel on this one

I’m with Marcel and Charles on this. Please disregard this question because it is in error and I have been corrected.

There is a minimum size requirement for weep holes. The 2000, 2003, and 2006 IRC all stipulate:

**R703.7.6 Weep holes. **
Weep holes shall be provided in the outside wythe of masonry walls at a maximum spacing of 33 inches (838 mm) on center. Weep holes shall not be less than 3 /16 inch (4.8 mm) in diameter. Weep holes shall be located immediately above the flashing.

Thank-you Marcel and Charles for forcing me to investigate further.

Your welcome John and I did not want to spoil the game prematurely, because this is how we all learrn.

For anyone looking for a basic on brick veener.
Sorry about the lousy diagram as it was my first.

John, it is pretty rare day that I don’t learn something:D and I am pretty stubborn:D

I think that John’s minumum might not be small enough. ha. ha.

Marcel :stuck_out_tongue: :smiley:

Ha Ha …Good one Marcel.

Hi. Bob;

Here is the other half. ha. ha.

I thought that was a pretty good commercial on the product.

Marcel :slight_smile:

One of the better product commercials and I noticed that the second one didn’t say that no humans were harmed during filming. Thanks, Marcel. :smiley:

I like that one even better as he sounds like Sean Connery

:smiley: It was late you are correct , Have not seen a code built in yet… Have a nice day!

Brick Veneer requires weep holes and flashing review basic brick construction techniques.

Take care,

Marcel, thanks for an informative and LOL commercial.
