I am installing a water heater in the second story of a residential home. Can I run the water heater pressure relieve into a nearby toilet vent stack?

Why is the vent pipe from dish washer over flowing ?

I wrote in another thread about my slow draining tub. The consensus is that I need a vent, preferably downstream from the sink ( many mentioned an AAV just beyond the trap) now my issue is that I have a pedestal sink, and the plumbing is not really accessible around the sink to put in any kind...

I have noticed water flowing from the water vent outside our apt, it has been running practically all day. Tried turning off the main water supply but it still runs. However, if I run the bath for a while it stops. Anyone know what the problem could be? Syngin

Hi, I think we have a leak in the main stack,there is water at the bottom of it and it smells like toilet water. Can this be fixed or do I have to have a new one installed, and is it expensive
