Review on 😎 Valterra F02-3106CL EZ Coupler Valve Cap with Handle - 3.9" Clear: Convenient and Durable RV Accessory by Alan Massey

I appreciate the handle but the 4 slots are more difficult to work with than the normal 2 when it comes to removing the landfill cover. In fact, I can't get this cover off even with huge cable ties! Good thing my black tank only has liquid and NO PAPER. I also replaced the end of the tubing when purchasing this item and used silicone on both surfaces before connecting them. Just too tight on my end of the hose. Too bad, because the pen is a good idea.
