Your 30WFKSS is the twin of my 3008W, so I am guessing your water pump is under the bathroom vanity. If you have not already, remove the screws out of the flimsy divider on the right and you should be able to see everything. As stated above, city connection ties into discharge of pump and any check valve would be right there. I keep my TT at my rural property or I would look and report.
