How to unstop double kitchen sinks?

+5
Answered

My sinks have water backup so I tried a plunger, then draino, a six foot snake that would not reach 3 foot without kinking up, used acid from Lowes, and then replumbed with all new pipes under the sink to the pipe going under the house. I don't have any problems with my 2 bathrooms or my washer just the kitchen sink not draining. It was draining over time but has stopped doing that now

    Are tree roots the problem? Broken or collapsed sections of pipe? How old is the piping, and what is it made of? Cast iron piping is notorious for decomposing over time, and may have crumbled. You most likely need a qualified plumber with a camera. Be sure to warn them about the chemicals you've tried. Most plumbers advise against Draino, etc.

    Belinda,

    It is time to bring in the professionals, we had the same problem with our double sink. Tried the whole gamut of things to do to it...hot water, the snake, baking soda and vinegar, plunger, just like you did, no luck.

    They have the tools to do a visual with their camera to see what is going on down there, hopefully your is a minor clog.

    We were not so lucky, the problem with ours was a big deal, the exit to the street sewer was blocked just after the wall of the front porch, the old ceramic tile finally gave out and broke (house is 60 years old), of course there were "items" stuck there too. The front lawn had to be excavated and the line replaced.

    I don't mean to scare you, hopefully you'll get through this with minimal problems.

    Looks like you have a clog further down the line in the pipes. I have a variety of snakes for different rodding jobs. A 1/4", 15 foot hand held drum snake would do the job. Only $15 at Home Depot. You need to remove the P trap and J bend from the wall under the sink. Rod directly into the wall.

      I took the trap off and went into the wall but I guess my snake was not heavy enough to do the job next is call the plumber. Thank you for all the help I really appreciate it.
