Picking up our new 328ts next week

[k3wtf]

Ok out this weekend before our trip to fla and can not get any water in the black flush. Like there is a blockage. I tried half pressure and all that and this is a new coach!! 1 st time emptying the tanks. What can I try??? It's a 328 2014 model.

Thanks
Joe.

What's happening? Do you have black tank drain open and hose attached to black tank flush and no water is coming out or do you have the black tank drain/valve closed?

Blade valve open hose hooked up and no water running in flush. When I take off hose water goes everywhere

We had same problem, the check valve is installed backwards. Best to have a dealer fix it. It requires special tools for the water lines.

Where is the check valve?

Sorry, mine is a 360xl and they are very good at hiding them. Mine were under the sink in the bathroom way up high out of site and the other was under the shower. My old one was with the washer/dryer prep hoses. Hope someone has a 328 and can tell you where yours is.
