Your kitchen drain is clogged, and you don't have the money to call the plumber. You've tried using the plunger, but you're not having any success. What are you going to do, no money to hire a plumber, and the plunger doesn't seem to be working effectively?
If you own a shop vacuum that can be used to suck up water, you could save yourself a couple of dollars. The first thing you're going to need to do, is to remove the filter from the shop vacuum. The filter is normally used when vacuuming dry materials like sawdust or dirt.
If you don't remove the filter, there's a good chance that you will ruin it, once it becomes wet. Make sure that you clean the shop vacuum out thoroughly and turned it on outside to make sure that it doesn't blow any dirt or dust out the exhaust vent.
With all that done, it's time to bring your shop vacuum into the kitchen and try to unclog your kitchen drain. I would imagine, since your kitchen drain is clogged up, that there is water in the sink. Simply place the shop vacuum hose end to the drain that is clogged and turn it on. Get as much of the dirty water out as possible and then refill the kitchen sink with clean water, enough to cover the clogged sink drain opening.
This time you will place the end of the vacuum hose into the sink drain, while using your hand to block off the rest of the kitchen sink drain opening. This will allow you to cover as much of the opening as possible. Now you will need to turn the vacuum cleaner on, while blocking the opening to the sink drain off, to the best of your ability.
This might not work the first time, so continue to add water, and repeat the process. If this doesn't work, and you have a double kitchen sink bowl, you might need to cover the other drain opening and try this again.
The purpose and objective here is to try to reverse the clogged object that is located with in the kitchen sink trap or pipes that take the kitchen waste to the sewer.
If you do this more than four times and it doesn't work, you tried, now it's time to call the plumber. However, if it works, you saved yourself a couple dollars. Don't forget that you can use this method for unclogging drains on bathroom sinks, toilets and even bathtubs.
