Ok, I'very been reading my manuals and on here. When I bought my 28BHBE, it was already winterized from the factory (picked up in Jan), so I haven't pushed water through it yet.
I've gone through for the hot water heater and installed the plug, and turned the valve to "inline" and ready for flow. And this valve is a PIA to get to in the small crawl space!!!
In this pic of the water pump assy, I see the bottom valve is "inline" and ready for flow.
Is there anything else I need to look at before hooking up water? I've read where to turn the cold on first and flush, then the hot. And once the hot water heater is filled, I can light it and test for hot water.
I didnt get a chance to look and see my low point drain area though.
Thanks for y'all's help.
