Mine works the same way. I just accepted it working that way. After my own frustration, I figure some guy sitting behind a desk on the 215th floor of a building in some country no one ever heard of had a brain storm of an idea! He's probably never seen an RV, let alone a campsite, but his marvelous new design sold! So here we are!
Hey! talking about toilets? did anyone see "Sunday Morning on CBS" this week! They had an article about Japaneese designed toilets. The thing that made me laugh was when they said, visitors to Japan get so confused when using them, they can't figure them out! Wonder when folks start putting THEM in their RV's! But at $20,000 a toilet, I don't think very many will be installing more than 1 in their RV! :B
