It needs to be 2" pipe, (not sure what you have now)
Never use a drain cleaner just use a snake. Will a snake cause a cast drain to flake off rust? Yes, will it plug anything up, no.
Should all cast iron and steel supply pipes be replaced with PVC yes. If it's not leaking now it will at some point.
Gurgling is caused from a pluged up or nonexistant vent. When water goes down the drain it's trying to suck air out of the traps.
Take a straw and dip it into a glass of water, now put you finger over the tip of the straw and lift up, what happens? Same principal.
Some times when the main line backs up or a septic tank fills up the sewer backs up into the lines and can plug up the vent line.
There's a trap. Follow the PVC pipe to the far end; black trap is toward the bottom of the picture; barely visible, but it's there.
2" white / black PVC was added by a plumber many years ago, just before we purchased the house; day or two before settlement...and just prior to township enacting new electrical, plumbing, etc inspections for house sales (found this out after the fact). Anyway...
The 2" from the washer and dishwasher (far end of picture) both flow into the cast (2"?) at the bottom of the picture.
Also, this may be something...may be nothing -- township was working on sewers in front of the house a few days ago. Had some kind of huge vacuum, I think. Heard the gurgling when they were working. They somehow sucked all the water out of the basement toilet -- sewer gas filled the house then (twice) ... Went out to talk with them; neighbor was walking back and told me he'd just told them the same thing. Someone up the line was having a problem. They moved up the street and opened another sewer cap; did the same thing.
