Low Flow Water Pump for Truck Camper

Hi fellow camper owners. (New here BTW.) I have a Lance 805 truck camper, which is a super minimal and lightweight no-frills hard-side truck camper from '07 (edited model from easier typo) . The only water use and plumbing is the single sink. I'm replacing the Flojet 03526-144 water pump, with specs of 2.9 GPM, 50 psi, and 5.2 amps. I'm thinking that I could get by with something more minimal, like under 2 GPM, since all we have is this one sink which splashes at the highest pressure anyway with the existing pump.

What do people think? Should I stick closer to 3 GPM and what I've been using, or could I get by with something like the Seaflo Water Pressure Pump 12V DC 1.2 GPM 35 PSI 21 Series from Amazon? Anybody else using a low-flow pump?

    Is this to prevent others from wasting water?

    I've installed that slowest pump on boats to do just that. It works. There is no reason not to use it.

    I've also installed foot pumps for the same reason. That REALLY slows them down.

    Nothing wrong with your plan, but if it's just for you, I'd turn the faucet on less.

    I’m not familiar with that model. Did you mean Lance 650? That’s a pretty new camper, and does just have a wet bath with a shower, sink, and toilet. No galley sink.

    I don’t think I’d replace the pump if the only problem you’re having is at the sink. The faucet should have a restrictor in the aerator. If it has a removable aerator, you may be able to replace it with a better one from a hardware store.

    I don't understand the splashing except when the system is first purged of air. To prevent the splashing during purging, just open the faucet before the pump is turned on so there isn't any pressure. Once the air is removed, the water flow should be smooth and only at the volume the faucet is turned on which should be fgrom a trickle to wide open.

    Full psi should only be found before the faucet handle so it really doesn't matter if you are using a 50psi or 20psi pump. The difference is only how much water can be pushed through the faucet.

    If the splashing is occurring at other times, please explain when it occurs.
