I've looked at the other "What pipe is this?" questions, and none of them that I've found seem to match...



I don't know what the large metal pipe is (on the right side). Can anyone identify what it's purpose is (or was)?



Roof with Pipes



It does not seem to be connected to anything; from what I can tell, it terminates right above a shower on the ground floor. There's been a fair amount of renovation done by previous owners and I suspect that this is a left-over that is no longer in use.

          Most likely an abandoned fireplace chimney, if evidence supports the theory that the bathroom under that area has been added recently. Otherwise they may have re routed a bathroom exhaust fan into it. Take the cage off and look down it with a flashlight.

          • Yup, if you look closely there is a inner section of pipe of a smaller diameter, meaning this is a variation of A vent or L vent. Lining the space in between the large and small diameter pipe will be a fire resistant concrete unless it's a custom built chimney and they only used air space as fire protection. In that case thank God it's decommissioned.
