Water Leaking via 1st Floor Bathroom (sink leaks)

Hi,

I just had 2 new skylights put in yesterday. It rained overnight. This morning, when I got into the 1st floor bathroom (not upstairs bathroom), there is a puddle of water right under the ceiling vent.

Looks like water went right through the vent.

Any ideas of what is happening ?

You have a leak. You'll have to do some investigative work to find the exact source but since you recently had work done on the roof that's a good place to start.

The leak is around the vent fan to the bathroom ? Is there a pip on the roof to the vent fan in the bathroom and that needs to be sealed ?

Hi,

The guys came back and installed a flash on the vent pipe. Now, the very next morning, when I use the sink in the bathroom, the water is leaking via the sides of the bathroom vent. Not from the inside, but from the sides.

The water doesn't drip when I just turn the water on. But I need to put the stopper on in the sink and let the water accumulate. Then when I release the water, the water starts leaking. Not a lot, but enough to wet a mop.

Do you know if this is related to them working on the vent pipe on the roof ? Could they had cracked it and this is affectbg the bathroom sink upstairs leaking to the bathroom downstairs ?

None of this is making sense. Do you have a leak when it rains or when you use water in the sink? Is this a leak in the ceiling or a plumbing leak in the sink? You've mentioned a skylight, the vent in the bathroom, a vent on the roof, the sink, the bathroom upstairs, the bathroom downstairs???

It haven't rained yet since he fixed the flashing for the vent pipe on the roof.

Not sure if its related or not, but now when I use the bathroom sink upstairs, it drips water to the downstairs bathroom only when I use the water stopper in the bathroom sink.

Have you looked underneath the sink for a leak? It's probably where the drain pipe meets the sink.

No leaks under the sink.

Let me describe the problem.

The water leaks to the downstairs bathroom. Under the sink is dry. The leak only appears if I fill the sink with water and then remove the stopper.

If I just turn the water on without using the stopper, no leaks. The handyman said its high pressure buildup in the sink drain line ?

Any ideas on how do I fix this problem ?
