What is it with these low flow plumbing products. It must be the law that you can’t have more than a light drizzle when taking a shower.
A while back I bought a Moen hand held shower head. I wanted the equivalent of a super soaker. I bought the highest flow rate model available. It was the only one, all the others are low and lower flow. Brought it home, it was pretty bad. Turned out that the hose end fitting was acting as a water restrictor. Drilled it out and it was way better.
Last weekend I bought another shower head, this one mounts on the pipe coming out of the wall. Bought the highest flow rate, again it turned out to be pretty low flow. Looked inside, found a restrictor insert and ripped it out. Works like a charm now.
