As is expected, we're fixing up all the problems it has (and the problems we've caused - I won't go into that).
I think you should go into the problems you've caused
Heh, well, not entirely caused by us. Apparently the last guy considered himself very handy, but still neglected fixing obvious things. When our inspector came through, for example, with zero effort he just pulled the spout off the tub deck in the master bath.
Well, the worst of it was that a toilet in the master bath apparently was running. The toilet got clogged, kept running, and overflowed all night. The water got everywhere, including one of the rooms in which we'd just installed (I'm talking three days earlier) brand new wood floors! Ugh. So one room and most of our master bath had to be removed. This has led to us gutting our master bath to completely redo it because the tub was cracked already.
Anyway, yeah, there are far larger problems in the house than an aerator, but it's still annoying
I'm assuming that you've removed the tap and looked on the underside? I can understand why the manufacturer might not put markings where you can usually see them, but...
You're talking about that main part in the middle? The spout? I don't know my faucet terminology
I haven't tried removing it, and I'm not sure how I would if I wanted to...
I've found that aerators tend to come in a standard and slightly smaller size. A quick measurement should tell you which. At less than $5, you can get one of each.
Yeah, that's what I might end up doing... The other problem with getting standard off the shelf parts is that most of them are chrome, so they'd stick out a good deal visually.
