This is my first post to any forum ever, so I apologize in advance if I'm overlooking posting etiquette that I'm not familiar with. I have read DIY forums for years and this one is by far the best for plumbing, so I come seeking your advice.
My question is - should replace all of my original cast iron pipe as I remodel and have better access to it.
My home was built in 1957 and has the original cast iron drain pipe, in a crawl space / partial basement. The pipe is marked "SOMERVILLE AV WT42 lbs".
I've read that average cast iron pipe life is around 50 years (and can be much longer) and mine is almost 60.
I'm remodeling the first of 2 bathrooms and had to remove all the cast iron under the first bathroom because I'm moving all the fixtures. I cut it all out yesterday and it is HEAVY!!!! I thought it would break up as I cut it but it didn't, they were playing for keeps in the 50's. It was like cutting through....well, iron.
The first 4 pics are of the main 4" cast iron pipe leading away from the first bathroom. The wall thickness is slightly less at the bottom left but still seems pretty good. It's hard to evaluate the interior. I don't know if this looks bad or not.
The last picture is of the interior of 3" vent pipe up towards the roof. It's in remarkable shape and I intend on leaving it. It give a good reference point to what the original interior of this cast iron pipe looked like.
Does anyone have experience with old cast iron and any advice on if I should leave the rest in place as I remodel or go ahead and replace it all as I go since it's so old and I'll have better access while I'm remodeling?
I can provide more details and pics if someone knows their stuff and can help answer this or at least speak from experience.
