I previously used the incorrect faucet connection, which resulted in a not-perfect seal and a very tiny leak when the water was turned on. It's really tough to find a hose barb to 1/2 NPS connection - key letter being the "S" in NPS, which means straight thread. There's lots of connectors for NPT, which is tapered, but faucets use straight threads (sealed by a rubber gasket / washer).

Old setup that leaked...​

Note that part #8 was a female NPT thread, which was the problem. The faucet stem is male NPS (straight-thread). So while female NPT somewhat threads onto NPS, there's no gasket to seal it, and even plumbers tape didn't seal the gaps.

New setup that doesn't leak​

The only place I could find a 3/8 hose barb to 1/2 female NPS was from Brew Hardware: 1/2" Female NPT/NPS x 3/8" Hose Barb. Kinda annoying having to buy a single part from a store and pay shipping, but literally that was the only one I could find.

And it worked!! No need for plumbers tape, the included gasket seals! Plus, it's a two-piece part, so it's easier to unscrew and re-screw it in the future (since the tubing doesn't have to spin).

Removing the old leaky setup...​

Yes, there was plumbers tape the whole way down. I took this photo after I removed the plumbers tape since the new fitting didn't need it.

Installing new correct fitting​

Look at that nice rubber gasket! And how it's a two-part connection so the barb part can spin separately from the hex part!

I have the Seaflo 21 Series water pump in my camper, connected to a LiFePO4 battery (which is up to 14.4V when fully charged or charging), and it was NOISY. It sounded like a jackhammer.

On Reddit, ihaveavanquestion pointed out that you can use these pumps at different voltages, and the manual did confirm this too, and it was right! It's significantly quieter running at 10.0V, and still has plenty of water pressure!

This is the DC Buck Converter I purchased: https://www.amazon.com/dp/B078Q1624B

It has high enough amp output for the water pump, and is adjustable, and works well with my existing power switch (it remembers what it's set to when I turn my power switch off, and when I switch my switch on, it comes back to the same voltage I previously set).
