sooo... just bought a home, we've been living in it for about 6 months and we now hear a drip between the first and second floors. The drip occurs only when the kitchen taps are running The second floor bathroom shower is in use The second floor bathroom taps are running Someone flushes the toilet in the second floor bathroom The drip occurs once a second roughly... and I think I might have heard a smaller second drip. So... does anyone have any recommendations on what I should do? I considered calling a plumber but I'd feel a bit better knowing what might be the problem before calling. Ken.
