All the homes I been in that where built in the 1950's have XH cast iron, heck I think even most of the homes in the early 1970's has XH in it. Done a few stack replacements in homes built in the 80's and newer they have service weight cast iron.

I really think PVC or ABS should be the only thing allowed in waste lines. I even have my doubts about ABS. But that is better then cast.

if it was banned then many of my service calls would go away after a while... nah, keep it, and I'll keep servicing it and selling repipes

No Hub and service weight are not the same wall thickness, no hub is thinner. The biggest problem I see with the cast iron pipe made nowadays is poorly spun pipe that is not the same wall thickness all the way around, but rather one side is thinner than the other.

I got these figures from the soil pipe handbook for 4" cast iron pipe.
Hubless: nominal o.d. 4.38" nominal thickness .19"
service weight: 4.30 and .18"
extra heavy: 4.50 and .25
Reference used: 2006 cast iron handbook chapter 5,Table one,page 72.

when I started no hub was just getting approval around here.(it was all poured joints terricada(clay) ,orangeburg,even see some cement in older areas) and we had a few years (2000 to 2008?? I think, help me master) that we could only use ductile between the house and main(for sewers) even on residental that was an over kill IMHO but we are back to normal and use what ever we want now as long as its approved by our enviormental services dept.(cast iron , pvc ductile etc). It was so much better when we had a plumbing inspector who checked out all the plumbing not just the sewers, jefferson county alabama is a strange place to work but I guess all places have their ups and downs Out in rural areas they have one inspector for everything elect, plumbing , foundations etc. 1 job 1 inspector eccept the septic system its state wide

Ductile for a building sewer...That is radical. hope they had c/o .

I'll chime in. My first impression of no-hub was that it was just plain flimsy. I haven't changed that opinion.

I have replaced a lot of both no-hub and ty-seal pipe that was only 30 years old. The pipe was not just bad, it was really bad. You could put your hand through it just about anywhere along its length (horizontal).

Now, duriron, that's a different story. Good stuff.

Trades should outlaw ABS and PVC, it is the material of handyman across the nation.

I pull out cast that is 40-70 years old, I pull out ABS that is 15-20 years old.

Think abiout it. Besides ABS and PVC dumbed downt he trade, looks like crap installed, Cast iron in my book is harder to move, but looks better installed and is easier to install.

DOWN WITH PVC AND ABS!!!

How does abs and pvc dumb down the trade but yet you say cast iron is easier to install?
