Seems like all the kitchen faucets are now flow restricted to 1.5 gallons per minute. Problem is, I have an on-demand hot water system that needs a higher flow rate to turn on.
Maybe someone has an idea where to get a faucet without this stupid restriction on it.
Looked at HD and they couldn't tell me which ones had this.

DIsassemble the aerator; flow restrictor is inside, fairly obviously (plastic washer, small hole). Enlarge with a slightly larger drill bit -- used as a hand tool, not in the actual dril. Reassemble.

Yep, that worked perfectly on my old faucet, the new ones not so much. I would hate to keep buying faucets to see what's in the guts. I'm going to have to return the one I bought today anyway. This one cannot be modified without destroying the pullout portion. It would then be unusable. Some faucets have the flow restricted by using very small diameter supply lines.

"ASME A112.18.1/CSA B125.1 standard for Plumbing Supply Fittings"
The WaterSense lavatory faucet specification sets the maximum flow rate of lavatory faucets and faucet accessories at 1.5 gallons per minute ... This specification applies to bathroom sink faucets or faucet accessories intended for private use...
Implication is that a "commercial" fixture would not necessarily be subject to this limit.
As usual, I'm mildly offended by the "one-size-fits-all" regulation which is basically irrelevant for the "off-grid country living" use case.

Well, I went to Ferguson and they found a faucet that was a 1.8 gpm. I installed it and so far, everything's working great.
Seeb, I forgot about McMaster-Carr.

Your problem could be caused by the limitations of your catchment pump,its location or restrictions caused by your filters.
You could add a booster pump.

ASME standard assumes 60psi, so yes, less might be a "problem".

My ecotemps have an adjustment screw (s) to set pressure - come set from the factory to not energize below 40 psi.....can be adjusted to operate as low as 20 psi. Some bosch units can be used as low as 4 psi for gravity fed systems .....Ive posted a link to the manuals - my hunch is many of the major china manufacturers use the same parts...just ordered a gas / water valve assembly with solenoid 27$

I'm on well water with catchment backup. My pump puts out 60 psi. I wonder of my water heater can be adjusted down.
