A lot of them aerators have a plasric thing that looks like a washer.
Has a hole about 1/8" in it. Just remove that piece and reinstall the
aerator. Or drill the hole bigger in it.

Removing that washer looking thing will increase water flow. Ugh,
I hate them in showers.

When I moved in 1983, it was before anyone saved water, but I took out
the regular spray head and put in a high volume spray head. It's very
nice, but I almost never take showers.

Before I move out, I'll put the original one back and leave the new one
in the mediciine chest.
