First cast iron job - Plumbing Zone

**Bill** · 09-14-2008, 12:15 PM

GC told me PVC waste and pex supply.
HO says cast iron and copper
HO footing the bill
Cast iron and copper it is.

Never done cast in a house, though I have done many outside drains with it. HO wants cast so he dont hear the water running. I talked to my dad and he suggested to do the horizontal and vertical with cast, but then switch to PVC at the traps. Makes sense, you will not hear the water running through the traps anyway. vents I will do in PVC as well. I am going to take some pix later on after its done.

First time for everything

We have done several residential houses like that. It looks pretty when you're done, black waste lines, and white vents.
It can help win bids to. Give a price for all cast iron then another price for cast iron/pvc with an explanation. If they bite on the PVC vents your price is pretty much guaranteed to be competitive. That is unless that is the standard where you are, around here we seem to be the only company that's caught on to that trick yet.

If you are using No Hub spend the money to get a torque wrench for it.

We use a cordless screw gun with a 5/16 (I think) socket in it. Using the torque wrench you can calibrate the screw gun to the correct torque. It's not a bad idea to check after ever five clamps or so that the screw gun is still correct or to even go over every clamp with the torque wrench. Saves a lot of time over tightening them all down with just the torque wrench.

That's a great idea.

I have a "T" torque wrench already. I always use it foe bands because if I use a 6 way screwdriver it ruins the end, or I overtighten the band.

Seekonk makes a beauty of a tee handle torque wrench!

When your running alot of cast its good to keep a few batteries on charge as well if your using your drill.
