Question about Dishwashers

3 Answers

My kitchen sink stopped draining. Under the sink I found a provent would this be the reason the kitchen sink isn't draining. Already used a snake no clogs found.

Double wide trailer if that helps. No draining problems in the rest of the trailer. Just the kitchen sink not draining.

    It's really strange that your sink won't drain but you didn't find any clogs with the snake. I'm having a similar problem with the toilet in my master bathroom; it won't clear but a snake went all the way through and didn't find anything. there might still be blocked drains somewhere, so I'm going to call a plumber to take a look at it.

That's a check valve so to speak...Houses have vents to the top of house..Most trailers have those check valves..When water drains it allows air to come in so it will drain..If it malfunctions it could be the very reason it doesn't drain...What I would do is stop up the right side of sink then fill with water...Then plunge the other side...If something's further than your snake it will hopefully unstop it and make it go on down..Hope this helps

My friend is actually facing a similar problem. However, I'm not sure if she's tried to snake the sink like you have. Last time I checked, she was considered going to a service provider since she's not sure what could be causing the problem. I also don't see anything wrong with getting a professional opinion if you've done all you can.

You need to pull the plumbing under the sink to see if the trap is clogged. Snake after the trap.

My kitchen sink is stopped up and i cannot unplug it! I have tried everything from draino to acid to snakes...still doesn't work!!!

I've had a similar problem and used a full bottle of main drain cleaner. It's only available at hardware stores and stores like Lowes and Home Depot. It should work unless you have tree roots growing into the main drain.

Double sinks in the kitchen are not draining properly

You most likely have cast iron drains.They work fine for 20 or 30 years or so. Then they rust from the inside out, they scale up sometimes to the point that they close completly off .My point is that any grease or food matter that gets in the drain can stop it up. the quick fix is to run a drain snake throught it then after you get it to drain you might use some professional drain cleaner to further clean out the line. If I'm correct about your drains, you ll need to replace them in the near future.

Won't drain water and backing up in sink

You have a clogged sink. Do you own a snake? (do not use any "liquid plumber" type cleaners in a kitchen sink as you wash and prepare foods in it).

Water running out from under the washer

sounds like two seperate problems. firsst water running from under your machine might be a bad seal, or water could be backing up the drain line. i would guess that it is a plumbing problem because of theissue with water in the sink. have a plumber snake out the drain lines and the problem with the washer should disappear.
