I'm understandning what you're suggesting...but wouldn't those aeras in question be accessible to the flow of water passing them by? I'm tryign to do this on my own and cannot remove a sink and disconnect driains, etc. Think hard on this...is there ANY other little likely thing that I can do that might work without dismantling the entire set up.
Let me take another look at this, Anatomy 101 under the sink/drainage apparatus. Am I dismantling the "U" shaped pipe under my bathroom sink?
I don't have the tools or know-how to remove the workings under the sink. But before I venture into that wild world -- what about if I were to take a shop vac, but it on exhaust (block the small overflow in the sink basin) and let the hose rip. Wouldn't at least in theory blow anything in the line away? If now the shop vac, then how about a power washer. That's certainly powerful. Just askin'
Got it...more later.
I've removed everything and understand what I'm doing and why I'm doing it...but I don't have the proper tools. More later. No one's around -- they were all planning on the Belmont Triple Crown today.
Wait -- there's more. You know I just NEVER give up easy. So in a blinding last effort I poured Oxy-Clean (peroxide) down the drain and added a huge pot of boiling water. Let's see. It drained beautifully -- the problem is not about drainage. It's about that odor.
Continuing, so I took a champagne cork and jammed it into the sink drainage hole. It if perfectly. I then took a mini cork and jammed that into the overflow drain -- so now there is NO odor, because there are no open drains. Seeing that I'm alone here anyway, when I have occasional to use that sink I'll just pop out the cork. Maybe by next weekend I can borrow the tools to do this job. Any OTHER ideas? Let me know. But remember -- there are not four teenage boys shaving over this sink. It's only me. I always have the little mesh add on strainer in the drain.
There is no last effort truth be told. I went to Home Depot. Bought a new Drano in a gel formulation. Pour in 1/2 bottle, wait 1/2 hour follow it up with a huge pot of nearly boiling water, heave-ho. Good. But this is not about drainage. I'm hoping that this will grab the offending plaque build-up and whisk it away. There's a real-life correlation with arterial build up. They should invent stents for plumbing lines. Anyway I just did this about 20 minutes ago. I'm closing the door and will await the diagnosis in the AM. I'm still looking at the shop vac. Why wouldn't that work? With the hose tightly affixed to the drain then power it up, vacuum out the already gummy material. I've used this same shop vac to remove wasp nests, etc. Worked great. Just another application.
