One slow drain is probably a local clog — a hair trap in the bathroom, grease in the kitchen. Two or more slow drains simultaneously means the problem is further down in the main line. That's a sewer issue, not a fixture issue. At this stage, a $175 hydro-jet clears it. Leave it another 6 months and you're talking about camera inspection, possible excavation, and a bill that starts at $800.
Gurgling means air is trapped in the drain system — which means water isn't flowing freely. This is almost always a partial blockage in the main line or a venting issue. Either one gets worse, not better. The gurgling is the drain telling you something.
You flush the toilet and water rises in the bathtub. You run the washing machine and the kitchen sink backs up. When water from one fixture appears in another, the main line is compromised. This is an emergency waiting to happen. The next step after this is sewage backing up into your home.
A bad smell that returns a few days after cleaning indicates active buildup in the line — biofilm, grease accumulation, or the beginning of root intrusion. Pouring drain cleaner on it doesn't fix the source. It masks it temporarily while the buildup continues.
Cast iron drain lines from the 1980s and earlier corrode from the inside. The inside of a 40-year-old drain line looks nothing like the outside. Grease, scale, and biological growth accumulate over decades. A camera inspection on a home this age almost always reveals something that should be addressed before it fails — usually at a time and in a manner that's far more expensive than preventive service.
