Lowest flow shower on the market

Hi Sophie, We've seen 1.4 and 1.25 -- here's a 1.25 from Niagara: https://www.amazon.com/dp/B003UQ17O4/ref=emc_b_5_t 

Hi Sophie, A list of WaterSense labelled showerheads and their associated flow rates is available on the EPA's website here: https://www.epa.gov/watersense/product-search.  Some flow rates are as low as 1 gpm (3.8 L/min). 

We have had a ton of clients use the Bricor 1.0 or 1.25 gpm showerhead! http://bricor.com/products/ We actually had a university do a mini "experiment" and tested a bunch of 1.0 gpm showerheads in their athletic facility, and the Bricor came out as the favorite. 

Bricor even has a 0.625 gpm, the Ultra Max Ultra Low flow. Haven't tried it yet! 

Hello, Could you told me if it is forbidden by the LEED standard to put an infrared tap in the toilet? Thanks; 

Ditto on the Bricor 1.0 gpm showerhead.  AM Conservation Group shows a variable 1.0 - 1.5 gpm, but I've not used it.

Is the infrared sensor control for a project in the US?  If so, and you find one that is with a WaterSense labeled toilet, I believe GBCI would accept it.

Sara, an infrared sensor is allowed, but we can't say the sensor/ timer will reduce our water use. If you have a faucet that has less than 0.5 gal per minute (1.9 lpm) flow rate faucet, then you can show the savings in the Indoor Water Use Reduction Calculator (Excel spreadsheet).  But if it is 0.5 gpm/ 1.9 lpm that is the same flow rate as the baseline faucet, so there won't be any water reduction. Earlier versions of LEED allowed the sensor/ timer as a way to claim water use reduction for the credit. USGBC found it wasn't as effective in practice, so they no longer allow it as a strategy for showing water reduction. We can still use a sensor faucet, we just can't take say the sensor itself will save water.  

The Niagara Conservation N2615CH Tri-Max 1-Spray with 0.5-1.5 GPM  lowest flow is 1/2 gal per minute  

Nearly all (or all?) of High Sierra Showerheads' fixed and handheld models are available in a WaterSense-certified 1.25 gpm flow rate.

I work with them, so yes, I'm biased, but customer reviews on Amazon on their products using that flow rate have been excellent.
