I don’t know if those wafers with a small hole in the middle are still there. They may simply make the shower heads with narrower passages these days.
You’d have to look. Some dis-assembly will likely be required.
You would have to use your best judgement, but you may also be able to drill out the small passage to increase flow.
The wafer looked like a washer with a very small hole in the middle. I just took it out. You might want to expand it by drilling a larger hole. It’s basically up to you if you want to restrict a little to cut water consumption and reduce your water bill.
I just wanted enough to shower off quickly.
What these enviro mellon-heads never seem to understand, is it takes a certain amount of water to clean off with. Reduce the flow and the shower takes longer.
Reduce the water in the tank, and you have to flush twice.
DUH!
“Reduce the water in the tank, and you have to flush twice.”
The bigger problem today is that most older homes have 4” cast iron main drain lines that were sized for the “high-flow” toilets of the day. Now with low flow toilets there is not enough water volume to create the needed flow velocity to move the “waste” out of your home, and the old cast iron is rusty and rough which only serves to catch waste paper and cause the drain to plug up.. New homes use 3” main drains to solve the problem, but they are more prone to plugging up simply by virtue of their smaller cross-section. That is “progress.”
