That’s what it sounds like, but - if this is a new issue, there’s something else. Unless maybe after all these years, this is the first time both showers were in use simultaneously…
We have only owned the house for 5 years, two of which we lived there. We rarely showered at the same time as our kids and this was not something I was aware of. Until having 4 adults in the house, all young women with long hair, it’s never been brought to our attention. They go out together and all get ready at the same time.
They were not so much complaining, (they have rented for 2 years,) just wanting to let us know in case we wanted to address it for the next tenants. Sweet kids and I will miss them.
