HD site says the stream is 2.2 gpm (gallons per minute). Kohler site says this model is 1.8 gpm at 60 psi. How do you owners find the pressure?

The pressure is great. This is a very functional kitchen faucet and easy to use when rinsing dishes or filling pots for cooking. No complaints.
1855302
The pressure is fine, although I haven't had occasion to measure actual gpm.
1855303
It seems decent. Slightly less pressure than we had prior. But a small enough difference that we quickly got used to it.
1855304
I find the pressure as good as any other faucet I've had in that sink. It's certainly sufficient for my needs.

I was wondering about that myself. I figured that with CA's crazy EPA regulations, faucets coming from there would be restricted in their flow.

Sorry, but I can't help. My contractor had replaced this item once and then had to replace the workings inside the handle twice. We finally replaced the entire unit.

The best way to find the pressure of your home water supply is to go to the home improvement store and get a water pressure test gauge, at the Home Depot near me it's a little over $11. You screw it on to an outside faucet, it has a garden hose connection. Turn on the water, and it will tell you the pressure. 1.8 gpm @ 60 psi is a water saver flow rate, industry standard is 2.2. I looked at the HD website and it says 1.8 for this model, so they must have fixed it. If your pressure is higher than 60 psi, than your flow rate wil be higher.

GPM Depends on your water pressure. However in my house it is about 1/3 of a gallon per minute. It has a standard threaded aerator.

I'm not positive on all this, but I believe the water pressure coming to your house from the city is around 120 PSI, but once inside your house it is reduced by a regulator. Depending on where your spigots are in line to the regulator you may have 40-60 PSI, or closer to 100-120 PSI. Perhaps the water feed to your hot water heater is before the regulator?

Occupants has nothing to do with this question , it's gallons per minute{ GPM} The hot water flow that you need is what you need to know, Input water temp. has little effect when buying like I do, With a bucket measure the water flow at a shower if it's 1.5gal a minute then buy a 3GPM unit and you will love it like I do mine. Remember over kill is best

Unfortunately, we are not able to provide a GPH estimate, as there are too many variables involved (water pressure and flow rate, system configuration, hose length, and so on). Sorry!

I also wondered about this when I first bought this shower head. We live in the country, we're on a well, and we have lower water pressure than you'd have in most cities. I have our pump set for 40 (lower) to 60 (upper) psi water pressure. I'm perfectly happy with the performance of the Speakman at this pressure, and I never removed the restrictor.

I have re-read the documentation that accompanies the pump and nowhere does it state PSI or head (height) capability. My experience with draining a 500 gallon holding tank: discharge is not high pressure, less than a hose connected to the house; it will pump at least an 8' head. The pump did not deliver 2500 gph.

I don't know if that's normal or not. All I can tell you is the owner's manual states 2.8 gpm @ 3200 psi, and it requires a 5 gpm @ 20 psi supply.

Hi Robert, sorry it took so long to answer your request. I've been in the process of switching out computers and I had quite a few problems. First of all, we love our KOHLER shower head. I didn't know there was a restrictor in it. I just thought our water pressure was low. If you find that there is one in it, please let me know. Good luck. I never thought to call KOHLER and ask them.

I had a problem with a 2.0 GPM showerhead and my Rheem 13 instant on heater. If you don't demand enough hot water (.5gpm) the heater will not even come on and I had a problem with the water temp switching hot cold hot cold. I went up to a 2.5 GPM shower head and it works fine. I personally would not recommend under a 2.5 GPM showerhead. If you're just using hot water it will be fine, it is true that the lower the flow the hotter the water. But if you're trying to mix hot and cold, if you anywhere near one-third hot and two thirds cold it won't even come on with a 1.5 gpm fixture.

I don't know. It is fairly low pressure but I don't know the psi. It is definitely less that San Antonio residential water system pressure.

At 8 feet the 91330 & 91335 model will pump about 30 GPM. You can find the "PERFORMANCES" chart in your owners manual on page %. If you don't have your manual, you can download it at http://www.superiorpump.com/Manuals/utility.manuals.html.

I have read elsewhere that it is 2.5 GPM, which is the legal limit, no matter if one or both are on, because the water pressure decreases when both are on.

The pressure on ours is great! Not sure about the specific GPM, but I would not say it is anywhere near low flow!

The pressure doesn't seem high to me unless I twist the unit to engage the "massage" feature, which I never do anyway. My home water pressure is between 40 & 60 psi, which is the most common range in the US, so you should be good to go unless you have unusually high pressure like people sometimes get with public utilities when they are very close to a water tower.

While I can't tell you the gpm the faucet has excellent water pressure. We are very pleased with it

The GPM for the shower head is 2.5 GPM but it does depend on your shower PSI
