    Main Stack No Hub Connectors
    2 issues here...

    1. The plumbing inspector told me that the 2 no hub connectors show here are not code. This is the main vent stack, 4" cast iron to 4" Schedule 40 PVC. What is an approved connector that complies with International Plumbing Code 2003?

    2. The 2" cast iron vent pipe you can barely see on the left has been cut off. It vents a toilet and a sink. It used to connect to the main stack. When someone added a bathtub drain, they cut this vent and never reconnected it. How can I connect the 2" vent pipe into the main stack? Does this connection have to be above where the bathtub drain connects?

    Ask the inspector what connecters would be acceptable to him and let me know. Regards, Tom

    As I mentioned in the "Reducing PVC from 4" to 3" thread yesterday, the accepted transition from 4" Plastic to 4" Cast iron is a CP-44.

    The stainless 'Crinkle' bands on a No-Hub band are made from a thinner walled material, while the stainless bands on Mission or Fernco CP-** are considerably thicker.

    Thanks for the specifying which transition to use. I will replace the no-hub connectors w/ the CP-44's. I'm still trying to figure out how to connect the vent from the toilet and sink into the main stack. Here's a picture from a different angle. Can you tell me how and where to tap into the main stack?

    *SIGH*

    I'm thinking you may have bitten off a bit more than you can chew, O_R.

    I'm not sure what your finances are, but it would really be in your best interest to hire a Plumber to walk you through this project on a consulting basis.

    Keep this in mind -- Every improper fitting you've installed that will need to be cut out and replaced is costing you a great deal of money, money that might be better spent learning how to do it correctly the first time from a Professional.

    My plan is to do the items that I can and hire out the rest. It sounds like this job may fall in the "rest" category. Let me ask you this, though.

    The 1-1/2" you see that's connecting to the main stack drains a bathtub in an apartment in the floor above. Could I wet vent the toilet and sink on the first floor by connecting to the bathtub drain?

    I'm the wrong person to be asking about wet venting -- We don't wet vent anything in my neck of the woods.

    If you're asking if you can connect the toilet and lavatory to the 1 1/2" bathtub drain the answer's NO. What vents the bathtub? Regards, tom

    I'm going to autovent the toilet and the sink. That way I can avoid tapping into the main vent.
