Infared automatic faucet - Tilted Forum Project Discussion Community

Can anyone please help?

I am interested in purchasing a touchless faucet for my kitchen sink from "itouchless.com" (not spam). It lists the water pressure from the faucet at 0.5-7.0kgs/cm, 10-125psi. I want to know if the pressure will still be sufficient to wash dishes or other things beside my hands.

Thanks in advance.

Youre lucky if your house even has 10psi of water pressure.........

That unit should be fine

If you have "normal" water pressure, that faucet will work. I think you are misunderstanding what that pressure rating means. Of course the outlet pressure from any faucet is always 0 psig (atmospheric pressure). The rating you mention has to be the allowable inlet water pressures for that faucet; then depending on what water pressure you actually have, higher inlet pressure will usually give you higher flow rate from the faucet. I say "usually" since some faucets have a "flow regulator" which gives the same flow rate over a wide inlet pressure range; the regulator is actually an elastomer orifice, the higher inlet pressure squeezes down the orifice while lower inlet pressure allows it to remain more open, resulting in a consistent outlet flow rate over a wide pressure range.

"normal" water pressure in most residential plumbing systems is close to 50psig, I'd say something like 40 to 70psig depending how far you are from the pumping station. I've seen 120psi at work when we were next door to the pumps. Unless you have a totally inadequate plumbing system, the pressure must be over 30psig; one exception would be a very rural low-tech system feeding from a water tank or reservoir giving only "head" pressure due to elevation of the tank, about 1psig water pressure for every two feet of elevation.
