We're in the middle of that right now. The manual is not for our WH specifically, so DH has to actually take a look. We used our new TT from May to Oct - darn short season with a new TT - and while it doesn't look terrible, and we could probably be perfectly fine for another season, it'll be replaced. Of course, first gotta get the model #. Amazon had some decent prices....depending on the model #.
Has anyone included the WH Rinse to their set up? There were a couple of comments on the Amazon page noting that they did a dandy job and how surprising it was to see how much crud came out. Any thoughts?? Seems like it was about a $10 or less investment. Maybe worth it, maybe not.
