Kitchen Sink Clog HELP!
Ok I have an older home. 100+ years. I have a kitchen sink that all of the sudden when I put on the disposal the water would not go down. I looked below and i see water coming out of the trap. The pipes are metal down there. It comes from the disposal to the trap then and U going up then to the main pipe down.

I can't figure out where the clog is. I put draino in the trap and nothing. I tried a hand auger but would not curve around both bends. I am thinking i should just cut the metal tube and replace with PVC?

I am no plumber.. I am pretty handy so have tackled light plumbing as far as fixing pvc pipes and replacing toilets but never had a clog like this. I tried plunging but it is so slow to go down if it goes down at all. I am afraid to push it to far cause the pipes are so old. I am looking for some help. Any thing you can suggest I would greatly appreciate. Thanks.

I removed the trap and the other U. There is not clog in the trap at all. I am going to assume it's further down the pipe. Is there anything else I can try besides liquid clog removers and augers?

Although you said that you had tried Drano, DO NOT USE CAUSTIC DRAIN CLEANERS.
IMHO, the best thing to use for clogs is a good non-caustic enzyme-based drain cleaner like DrainCare. It won't harm fixtures, pipes or you, unlike caustic drain cleaners.
You just run warm water into the drain and pour in DrainCare. Let it eat out all of the organic gunk (grease, food particles, etc.) overnight, and then flush with very hot water. I always start the flushing with a kettle of boiling water. If the clog is really bad, you may have to do it more than once, but it usually works when all else fails.
Good Luck!

Mike's suggestion about enzyme cleaners is a good one. I have a clog-prone slow-running main line that runs under my slab the length of my house, and the enzyme stuff keeps it running. I use it every couple weeks and it works great.

Thanks guys I found the copper tubing to be pitched at an odd angle. We put a new bracket on it and poured some more cleaner in the drain. I also tried to shove a power auger in there but I don't think that thing did anything. The clog opened up a bit and water started to pass through. I put on a new trap and I can run the kitchen sink now. I am going to the enzymes I will have to find where to buy them. I didn't see much at Home depot or lowes. Thanks again I will keep you posted. The main on this house where the the sink goes into is a real mess. I was going to cut the copper pipe at that part and try and auger it right there but I am not going to mess with it. I will try the enzyme first.

Lowes sells a product called Roebic K97 main line cleaner. That's what I've had good luck with. Last time I checked HD didn't have much other than the caustic stuff.

Find a real plumbing supply house. They should have the stuff you need.

Just chiming in on the drain cleaners. Draino really can hurt your piping, and as you've seen, usually doesn't work too well. Try the enzyme and then you might want to auger the line. If you can get it fairly cleaned out it will be much easier to keep it clear with the enzyme based products.

What is the problem with Drano exactly??? I used it before asking :censored: We have an old house, not sure of the drain pipes, I would guess cast iron?

What's the problem with Drano?
I'm not saying 100% that Drano and other caustic chemicals will damage your piping, but it is certainly possible. This is especially true of older, thin brass and copper piping, like a tub waste and overflow. Drano is also not good for the bacteria in septic tanks.

I guess my take is that I have had lots and lots of people over the years tell me that they "tried Drano, but it's still stopped up" so I figure why bother if there is even a chance it could do more harm than good.

If you used Drano and it solved your problem, great! If it didn't, just make sure you try to avoid getting any on you if you decide to take the next step and unstop the drain yourself manually; which is often something that most people can do.

it didn't solve the problem, go figure.
