We're looking at an old 1912 Victorian, which has been partially restored, but still has a number of needs. There are really 2 main plumbing issues we are wondering about, which I will post in two separate messages:

There appears to be no venting, using sinks/shower results in gurgling as water drains,etc. I have seen on here mention of mechanical vents that can be added to the sinks, but never installed one - easy enough? Also, how if at all would these apply to the bathtub drain? Since the house has never had these, my wife thinks we should leave it alone - so, besides the gurgling, what issues exist by not doing anything? Thanks

1912 Victorian we are looking at, I noticed it has old galvanized supply piping. The HI I went through with said it would likely need to be replaced in the near future. We also see rusting in the large cast iron drain/waste piping, and presume this will be a near future replacement as well. My question is, are these typically straighforward replacements? The are readily accessible from what I can tell. I'm trying to get some sort of ballpark on what to expect cost wise, or at least what conditions might influence cost when replacing these... Thanks

No repipe job is a straighforward replacement. It's all customized for your home and you can't "ballpark" that. You're going to hafta decide on what you wish to replace the pipes with. Copper or plastic. I would go with PVC and CPVC if it were me. Good louck, Tom

Without vents it's possible for the suction to pull water out of the trap so sewer gas can escape. To add a AAV,(air admittance vent) (see image) cut a upright tee in after the trap and install the AAV on the tees upright branch. Regards, Tom
