For a pump-fed system, the recommended pump specifications are:
Minimum flow: 1.5 GPM (to match or slightly exceed the spray valve's demand).
Operating pressure: 30–80 PSI (50–60 PSI is ideal for strong performance).
A pump with 2.0–3.0 GPM is also suitable, as long as the pressure is regulated within the faucet's operating range.
A pump rated around 1.5–2.0 GPM at 40–60 PSI is generally the best choice for consistent high-pressure rinsing.
