Damp Proofing

Transfer of driving rain water to inner leaf of cavity.

Hi I had a boiler condensate pipe running under the floor of utility room and out through the wall to a drain. This wall is at times subject to severe wind driven rain, which obviously runs down the back of the bricks when they are saturated. The opening in the wall for the pipe was just about at the height of the dpc. Because of frost risk, I changed this arrangement and ran a new pipe to internal sink drain. My builder replaced the bricks where the old pipe had exited the wall and pushed the pipe back behind the facing bricks. I’m now worried that if he didn’t think and pushed the pipe in at the wrong angle, it will transfer driving rain water to the inner leaf and that if the pipe comes through the inner leaf just below the dpc I won’t know anything about it until the breeze block has decayed and serious damage has occurred. Would this actually rot the block or would it just get a bit wet and dry again without any harm? I don’t want to make matters worse but I’m wondering should I remove the bricks and check what way the pipe has been pushed in behind them. Any advice would be greatly appreciated. Thank you
