My kitchen sink recently clogged for the first time. I'm sure it will be easy enough to clear the clog by disassembling the trap and clearing it out. I might also replace the existing trap with one that has a cleanout. However, I'm wondering if anyone has suggestions on how to modify the trap to reduce the risk of clogs in the future. I've lived in my home for 2.5 years and this is the first time it's happened after an absence for 6 weeks when the plumbing was not used.
(Another thing I noted is that the dishwasher drain is located after the trap, which from my understanding, is a bad idea and should also probably be relocated.)
As was pointed out, this is an S-trap and not a P-trap. It seems like the easiest solution is to install a sanitary tee and replace the S-trap with a P-trap and an air admittance valve since I don't have a nearby vent pipe available. Does this make sense?
