I recently had a pipe break in my powder room downstairs. The pipe
was fixed rather quickly.

This room is being renovated now, so there is no running water in
there.

However, we are experiencing mild water pressure related issues in our
upstairs bathroom.

1 of our 2 sinks in our double vanity has low water pressure.

Additionally, our toilet has been flushly strangely (take a second or
2 longer than usual).

The other sink and shower, as well as the rest of the first floor has
no water pressure issues.

The contractor is going to look at it today, but I was wondering if
anyone else has an idea.

I am clueless with this stuff.

Thanks.
