Water Pump and Battery Question
While sanitizing my fresh water system and running water through the cold and hot supply lines, we had the lights on and when I opened the hot water faucets, the lights flickered and the water pump wa...

I don't know if the voltage drop is a problem. If only 1 battery, that doesn't sound too far off.
As far as the hot versus cold water, I think it was hammering a little on a head of air as it fills the water heater tank. Most RV systems will hammer a little at first, until the system purges air, or at least compresses the bubbles of air.
You might want to adjust the pressure regulator on the pump downward just a little. I've learned that when running on battery power only, the pumps sometimes struggle to reach the pressure setpoint with the voltage available. Less of an issue when hooked to shore power with a strong 12v converter keeping the voltage up. More of an issue without hookups as the voltage tapers down. A slight adjustment of the regulator makes it all happier, and the pressure you feel at a faucet is not even noticeable.
