Those are models I wouldn't be interested in purchasing.Many shower heads today achieve the 2.2 GPM ( some now even less) by internal design, not a simple restrictor at the inlet.
If you choose not to work within the framework of the law and the water conservation needs of your community, you are on your own.
Well, you didn't mention the shower head was for the pigs. I imagine the farm supply stores must provide such products? Problem is, if you want to buy it at the human store, it will have human rules. And back to the basic question, I don't recall any shower head today which uses a restrictor at the inlet. There probably are some. You could go to the store and look at them.
Well, I am sure that someone will need a shower if they only take one every two weeks after working on a farm.
But I, and most people, take our clothes off before taking a shower, but if we did not, a garden hose with a good jet nozzle would knock the dirt off, and then we would put them in a washing machine, not keep them on while taking a "normal" shower.
I don't blame them for being initially hostile to what sounded like an unnecessary attempt to operate outside the law. Had you stated the purpose differently I doubt the initial response would have been the same. I've not noticed an environmental bent among the mods.
This is the first time I am hearing that it is illegal for us to change the shower flow. can someone give me more details about this?
