When you turn on the pump for the first time all the plumbing might be full of air. I think you said the coach had been winterized. It is going to take a time for the pump to fill all the plumbing lines with water, including the hot water tank,.
You might need to purge all the air, from the lines to the bath sink, the shower, and the toilet. Our system spits air for some minutes after a complete drain down.
When we picked up our U225 that had been sitting all winter, I found that I had to take apart the shower drain down fitting at the wall. This is where the shower hose attaches to the wall fitting. Inside that fitting, I found debris that was blocking good shower head pressure. I then took off both sink spout end fittings and cleaned the screens.
The sprayer is best used to squirt into the toilet to clean the bowl, carefully.
Wasps love to go thru the hot water grills, and the furnace ones as well. They build nests, same with mud dabbers. I have added aftermarket screens to help stop them from getting in. Know you now will need to clean the flame chimney, completely from the burner to the top of the exhaust stack.
Don't think you have a manablock on a U300 in 1993.
