    I have a leak from a 4 inch cast iron vent pipe in my basement. It appears to have rusted through and it is dripping. It is very smelly. I am not sure what can be done to fix it. I am guessing it is just rain water that has collected in the pipe that is rusting it out. Since it is just a vent is...

    is it OK to leave a vent pipe open in an unused attic (just really a gap between the ceiling and roof, too small to be used) if there is a sizeable side wall grid vent, maybe 4x10" within a foot of it or so? i just don't feel like drilling through the roof and sealing it and all. currently...

    I have a silly question. I have 2" ABS DWV vent pipes penetrating the roof. My roofer will waterproof everything. But I don't know how to properly terminate the pipe over the roof. Put a metal cap on it? Thanks for any suggestion.

    We are desperate for some help! Our one-story house was built on a slab in 1974 and is in Arkansas on a very flat piece of land. There's been a lot of precip for the last 2 years, and the drainage is lousy, so often our yard has spots of standing water or is squishy to walk on. Our septic tank...

    Can I combine multiple vent pipes into a single vent pipe in the attic? I am in the process of installing a metal roof. Currently there are 5 vent pipes exiting through the roof (1.5 to 2 inch pipes) and I would like to combine the pipes into a single large pipe that will exit through the...
