My boyfriend went to fix the little plate that says hot and cold on our bathroom sink as it was crooked. He pulled up and the whole top came off and our bathroom became a waterfall! It took us forever to find the water shut off. We tried to put all the parts back together, but every time we turn the main water on it still shoots out.

Replace the faucet assembly with a new one...

I was trying no to do that, but I guess I will have to. I didn't see any parts that were missing, so Im not sure why its not working! We have a very old house, and in order to turn the main off we had to go outside by the water spicket. So we can't use any water in the house. I was just going to try to fix it before he got home so I can use the water. :(

No parts that contain the pressurized water should come apart with a pull or a tug... and if they did they simply won't go back together.

They have simply worn or corroded beyond their service life.

There should have been two shutoff valves for that sink... under the sink... one for the hot and one for the cold.

OK thank you! :)

Any shutoffs under the sink?

No there wasn't any main shutoffs in the house. We went a replaced it. Later after we turned the water on, we found a piece hiding in the shower. It must have flown in there during the explosion! So, if this happens to someone else, search the whole bathroom for any stray prices before you go out and replace it. Lol
