Clogged Drain Line question

Sorry for the long post, but I wanted to make sure to give some details.

I have a clogged drain line at my house (built 1966) which has kitchen sink, dishwasher, and washing machine draining to it (in that order, upstream to downstream). I have easy access to a cleanout at the washing machine. This is a secondary line which connects to the main sewer, which luckily is draining fine itself. We've had a plumber snake the drain many years ago and it worked well for quite awhile though gradually draining slower over time as to be expected. Recently, it stopped altogether. Knowing this day would likely come and hoping to not have to call a plumber out each time, my wife bought me a Ridgid K-400 drain snake a couple of years back. (Admittedly, had I used the thing earlier I may not be in this predicament.) I suspect that the drain is 1 " as the only cutting tools I can feed in the drain are 1".

Last night I used a "C" Cutter twice and a spade cutter once all for full 50' cable length, but saw no improvement. After each pass, I turned on hot water in the sink (about half pressure) just to see if anything would flush out. At the cleanout, water that was basically solid black would pour out for a bit followed by gradually clearing water (with some small black "debris") followed by completely clear water. When I used the spade cutter (the 2nd of the 3 attempts), it had some black "gunk" on it when I retrieved it so I know it hit SOMETHINGbut the clog still seems like I've had no effect on it.

My guess is that the 50' cable length isn't quite reaching the full length of the pipe. I'm thinking my options are either buy a longer cable at around $150 (but I will have it the next time this happens) or call a plumber out (assuming they'd have a longer cable or another alternative.)

Thought I'd see if any one here had any other advice or experience. Maybe this is one of those "on the 7th try, it worked like a champ" situations.

Go to Home Depot and rent a Drain Cleaner 75' x 1/2" for $50 for 4 hours. Much cheaper than a plumber or buyer a longer cable...you can thank me later!

sounds like it's time to run a camera in there

Pour a whole gallon of bleach down the most upstream drain and let it sit overnight?

Then snake again?

Thanks. I had looked at that but hadn't decided to pull the trigger yet. While only 1/8" wider than the 3/8" cable I already have, I wasn't sure if the 1/2" would still manuever ok in a 1 1/4" line. Maybe I was paying too much attention to the 'for 2" to 4" diameter drains' description on the HD website.

Garbage disposal on the upstream sink drain ?


You can try running a garden hose down the cleanout and if that doesn't work a drain bladder will usually do the trick.

Once it is flowing again I would recommend running a drain conditioner every 30 days like this one

They also have 100' 3/4" Clean out...FYI...I'm getting the info from their rental sheet that I got from them!

JP76 - I had already tried the hose with and without the bladder with no success. Not exactly sure what the pipe routing is but I couldn't get the hose down the drain very far at all. I figured the bladder would expand to the pipe diameter no matter the depth, but it never seemed to get a good enough "seal" and the water would just back up and out the cleanout.

Originally, there was no cleanout at the washing machine. When the plumber snaked it many years ago, he added a cleanout with 2'-3' of wider diameter pvc. This is all within the wall above the slab. I couldn't seem to get the hose beyond the transition from wider pipe to the 1 1/4" that happens at or near the top of my slab.

I work for Ridgid, the K-400 is great for small jobs in 1-1/2"-4" pipes but from all that you have said, I think you need to have a camera run down the line. If the old lines are cast iron you could likely be looking at a collapsed pipe at this point. If you want to run another line take note on our line suggestions. 3/8" cable is best for 1 1/2- 3" lines, 1/2" cable best for 3"-4" line no long than 75' in length.

Ditto what JuCo CH46 wrote. My house was built in '63. Your scenario is exactly what I encountered at my house three weeks ago. Kitchen sink wouldn't drain. Laundry/Utility room affected. The plumber couldn't get through the blockage. Black goop coming out of the cleanout. Slimy, greasy, mud on the bit.

Long story short...............a collapsed cast iron drain pipe under the foundation. Three solutions were offered: cut through the foundation in the utility room to access the damaged pipe; or re-pipe by digging a trench around the house to the sewer line (required cutting through quite a bit of concrete; or dig under the foundation to locate the problem and repair.

I chose the latter.

Good luck with this!

Do you mind if I ask about cost/quote? I think I am having the exact same issue...
