For most people, seeing a ring or another object circle the sink and then go down the drain is an extremely frustrating moment. While many people believe that the object is irretrievable, it is not impossible. In fact, the first thing you should do once the item falls into the drain is turn off the water!
If you would like to take a stab at retrieving the item, here are some things that you can do before you seek the aid of an emergency plumbing company:
Stick a coat hanger down the sink.
Even though it sounds improbable, some people have found success with using a coat hanger to retrieve their items. The only catch is that it might be able to remove larger items as opposed to a smaller one such as an earring.
Attempt to take the sink apart if you are savvy with plumbing systems.
If you know the ins and outs of taking pipes apart, go ahead and try to retrieve your item!
However, remember that you need to turn off the water BEFORE you grab a wrench out of your toolbox and start unscrewing your pipes from the wall.
