    I have this problem annually, ever since the local laws preventing the Hot Water system to the house go above 65°C for safety reasons. The hot water is just not hot enough to melt the fats and other particles, so they build up on the walls of the PVC pipes. I decided to buy the machine to clean out the drain and set about tackling this messy job annually. If you used near boiling temperature water when cleaning the kitchen utensils I am almost sure that the problem would disappear.

    Dump baking soda down the sink and then pour vinegar any kind will work. First try a plunger. Also they have these special pressure devices sold at lowe's or home depot that work great too. Good luck; welcome to home owners life.

    I use the baking sofa and vinega method. I let it sit a while. I flush it out wth hot water. If that doesn't do the job I employ a plunger. My sister was amazed as paint brushes came up out of drain!! My young nieces were the culprits.

    several ideas to try. When you use the baking soda and vinegar method flush with a pot of boiling water. If it is grease buildup Dawn will help break it down. Pour in a 1/4 cup and let sit before flushing. If that does not work use a plunger. In some cases something could be stuck in the trap. Place a bucket under the pipes and disconnect the pipe coming down from the sink,just above the trap. Then twist the pipe so it points downward and drain out anything there. If that does not work rent/buy a drain auger. Run it into the pipe; while twisting. Guide it in as far as it goes. Then pull back out to see if it picked up anything. If all else fails call the plumber.

    Ca you access the plumbing vent on your roof? When all other efforts failed, my hubby climbed up to check the vent stack to discover a bird was nesting there. With the vent plugged with nesting material, the sink was slow to drain.

    Bring about 1 lts of water to a boil. Then take salt and add a good amount into the sink (maybe 2/3 to 3/4 cup). Then add the water and let it wash the salt. After that, open the hot water and let it run for a little bit. Hope it Works!! =)

    I agree with the boiling water method. Take all your biggest pots & pans, set water to boil & pour boiling water down drain, as much as you can, until the sink is full.

      Yes, and the salt helps clean the pipes. Not baking soda with vinegar, just salt. ;)

    Our plummer told us to use bleach every now and then to keep the pipes free in our laundry room. I have been doing that about once a month....3+ cups and have had no more problems. Have used it in the bathroom also. I do agree with the vinegar/soda/hot water method also. My DIL uses it frequently.

    Buy a new toilet plunger for this sink and try that along with these other liquid ideas.

    Put a half a box of baking soda then pour vinegar down the drain and wait 10 minutes and let the hot water run and it should be clear.

    use what the plumbers use. A water bladder to unplug a drain. Cheap and easy to use. . get at lowes or any hardware store.

    I don't have an answer we've tried drano and even a plunger quite awhile after the drano. Plunger brought up Mud. I bought a 16 ft drain scraper thingy it didn't work. I'm waiting for your answer too
    • Deanna Nassar Deanna Nassar on Sep 24, 2016
      Marie, if you are getting back mud, the drano is you clog. It sometimes will gel like that. I recall uncapping an outside clean out after using drano and the whole plug slid out. USE GLOVES and disconnect the pipes under the sink and try again with the snake. Check the pipes you take out for any remains of the drano. It may be possible for Roto-rooter or similar company to run a power snake through the whole thing. They usually work through the main house clean out which is outside the house. Ever see a large piece of pipe sticking out the ground, with a cap, near foundation? That's the main clean out port.
