What is the purpose of the flow restrictors?

For each Koehler product they are designed for a flow which in turn creates noise. That flow/ noise is why they create the flow restrictor to fill the reservoir completely but quietly.

The only flow restrictor I saw was the thick black washer which slow the water flow a lot. After removing entirely the water pressure was good.

did not seem to reduce water pressure or flow, did not notice any restriction

Yes, it has a flow restrictor, but the flow rate is very good. I'm extremely pleased with the quality and functionality of this faucet. It is everything it is described as being and looks as good or better than the picture. The flow rate may not be quite as fast as an "open" faucet, but it's a tiny trade-off for having the pull-down spray function and a beautiful, heavy-duty laundry room faucet. My husband said the install was easy and everything is included. We were both totally pleased with the purchase. Hope this helps.

I don't remember. I think there was a plastic washer that I took out, but I'm not sure. Our does seem to have good flow, so it does not feel like it is restricted.

I restricted the flow on the 2 pumps I bought, it did not damage them. The pump did not work any less just a slower flow of water.

Quite possibly it is for short circuit deflection. Used as a way to stop a spark of static electricity from flowing back to the A?V receiver. Consider it a bit of extra protection in either case.

It does NOT restrict the flow, unless you turn the dial to restrict it yourself. This valve can be adjusted to full on, or off and anything in between.

Flow restriction. Rip it out with a pair of pliers. It's a little tricky to get out.

In the product manual, it says, "There is a water-saving flow restrictor which restricts the flow to a maximum of 2.5 gallons per minute (gpm)."

It will slightly restrict the airflow just because it has parts sort of in the way, but air can easily flow past those parts. If you need to block airflow more thoroughly, you will need a separate mechanism to do this.

This item does not come with a flow restrictor. Meanwhile, the waterflow is around 2.4 GPM.

I do not know it's purpose, however I am confident it is part of the unit design/function.I would not remove it. It almost appears to be a filter for the unit fan. Again not sure.

Yes it can and I suspect that is intended use. It does restrict the flow about 20% however.

Removing the flow restrictor is absolutely necessary for good pressure. Directions are included and it's very easy. I am very happy with this combo.

To my experience all flow restrictors are easily removed, probably because they are only required in the USA and therefor a quick and dirty add on. I just stripped one out of a Hansgrohe hand shower easily with a pair of needle nose, although it might have fallen out with a good shake, but the holder that threads on to the pipe had one that was installed with a one way push in clip. Easily destroyed and removed with a small screw driver, not quite as easy as usual.

The purpose of the valve is to prevent back flow into the house...it is a one way valve so it cannot have flow in both directions.
