Looking for opinions on the severity of main vent corrosion/damage.

View scope video here:

• You can see what the cracks in the pipe from 0:43-1:19
• At 1:32 you can see he knocks some corrosion off and into the pipe and then from there he can't get the scope down into the 90-degree bend

Is this an absolute must-repair situation? How damning is this on a new home purchase? Pulling it out and replacing it requires pulling out countertops, cabinets, appliances, etc. Any experience with Nu Flow? Is this better or worse than I think it is? TIA!

Yes you will want to repair if the cracks are completely through the pipe. It will be leaking sewer gases into the structure.

Around here they have a company that lines the pipe rather that digging and removing. As I understand it, they send a grinder head through, and pull some type of fabric through at the same time. They then inflate the fabric, and it hardens. It costs about $100 per foot, but is cheaper than ripping out a concrete patio or stairs, etc.

Damn Jeff a 100 bucks a foot. It is time for me to start looking into the pipe lining business.

jeff is right reline is the best option may be a bit pricey but way less labor intensive and were it will last forever we have drains relined at work under granite slabs /6-8 feet below tile floor in a commercial kithchen

Thanks, everyone! Nu Flow is the company here in Phoenix I've found to do the relining option and they are coming out to quote on Wednesday. I think that will be our best solution here as well.
