Welcome aboard! Let us know more about you and your set up. What are you towing and what are you towing with?

For the water pressure, it's possible that the source has low pressure. You might put a pressure tester on the spigot you're connecting to to test that first. We've been in parks with low pressure (30-35 psi) so not much else you can do except maybe fill your fresh water tank and use the pump. You might do that anyway to see if the pump provides better pressure as a comparison.

Are you using a pressure regulator? Is it adjustable? Where's it set?

That's where I'd start. Give us more details and I'm sure there will be some good suggestions.
