Review on 💦 Valterra R920TW Telescoping Gravity Water Fill: The Perfect True White Solution by Mike Wieneke

I was expecting this to have an o-ring or something to prevent water from running back during filling. It was disappointing that this was not the case. My build is a van conversion that had this on a cabinet panel in a sliding door and would cause water to run down the panel and pool in the slider step area. Unacceptable. May be suitable for outdoor installation on a van, but water will still leak when filling. A good idea for a telescopic dam that just wasn't thought through at the design stage.
