does it actually adjust the water pressure or just the opening size?

It doesn't appear to adjust water pressure- shower head behaves the same just has less volume going through. Its possible that the water pressure is rising with the reduced volume of water. I installed one of these and my wife never noticed- I'm guessing I reduced volume by at least 40-50%. Win win for everyone!

It adjust the flow rate through opening size therefor adjusting the pressure as well. I've got mine working finally but you have to wrap the threads several times with teflon tape to keep it from leaking at the connection.

I hope this is the answer to the question you are asking..... It seems to me that it reduces the flow or volume of water that emerges from the shower head. Before installation I had a high volume with strong force.... water splashed out of the shower stall door. After install the water flow was greatly diminished. As I wrote to another person... I installed this in the guest bathroom at my summer home with two goals.... 1) to reduce the mess 2) to provide an unsatisfactory guest shower so that they leave on time and not linger for "a few more days". Both goals achieved.

The gardena has two knobs that adjust the water jets, they that can be adjusted to make a wide or narrow "rain" outcome, the length that the water eaches alsoa can be easily adjuste. you may get beeter results if you install a sort of small watrt pump to raise the pressure until 18 psi, mine gardena works perfect anafter several trial I found the settings I nned to watering my garden. hope this answer be useful Eddie

It is adjustable based on the nozzle you use and the water pressure to it. Make sure to buy the hunter key tool for installing nozzle and adjusting head. I have 4 on the same zone all going 20 feet or so.

These do not change the water pressure. These are shut of valves that reduce the volume of water and they can be used partially open or fully open. There is a big difference between the two. These are 7/8" fittings.

Its an oval opening and it is 7" at its widest front to back and side to side, I really like mine, but you do have to clean it regularly, and you really should buy a regulator to cut the water pressure down, I have a regulator on mine and its going on 2 years old. I dont believe it would last very long if you hook it up to house water pressure.

Not really. The only way that I have found to play with the width it to lower the water pressure. You can adjust how far it travels from side to side however. Hope this helps!

It does have an adjustable flow nozzle although I've never had to use it. Once the system is laid out level and pressure equalizes in the hoses, I personally haven't experienced a noticeable difference in pressure. If a difference in pressure does occur, it's an easy screw-type adjustment or you can make up for it with the layout of the hoses.

It's really a function of the nozzle you put on it. The diameter of it seems to be narrower thanthe normal hose and I have no problem than with the pressure.

No it isn't adjustable. However, my family and I find the pressure to be just about right. I have one in every bathroom in the house.

Doesn't need much, uses a small amount of water and it makes it's own water pressure.

No. It does work to smoothly open. Was fairly difficult to adjust, as it came with no directions for adjustments. But, it was cheap.

there is no water flow adjustment, it basically streams water until hot water is detected and almost cuts the water flow completely down to hardly anything, until you pull the lever and then you get full pressure for the remainder of your shower

I haven't noticed any pressure. It's also adjustable so even if you believe it does, you can adjust it to where it doesn't.

The water pressure is good, will be close to the actual pressure that you have with maybe a little bit of improvement. nothing noticeable for me.

For those who say that the pressure is adjustable, please explain how. The only place I can see that you could possibly adjust the pressure is at the water intake vale at the base of the toilet. I guess you could adjust the pressure there, but it seems a bit bothersome when my family and I find the pressure is just fine. But, to each their own.

No they are not adjustable. Some "play" in amount door can be opened with pressure.

There is an adjustment valve on the handle. It allows for pressure control also.
