The Wild Dog wrote Question about these city fill inlet valves... Have you ever seen any that have an option for a locking outside cap ?
All I see on these are just pop off caps. I'm kinda concerned about people putting stuff inside them while the trailer is sitting at night,
Why would anyone want to drag a hose to your trailer and hook it up and pump God knows what into your fresh water tank?
That isn't going to happen so don't worry about it.
Chef Bubba wrote Or you could use one of these,
many HD's require this type of fill system. No one can tamper with the water tank, and you wont be sticking a dirty hose end down the fill pipe. The only bitch is, if you loose the fill end, and your on the road, .........you better have a spare!
Chef in my opinion that rule came about through someone that sells these units. But that said they look like a common quick connect fitting that you can buy at Lowe's or and good hardware store, for much less in fact about 10% of your fitting total cost.
The only rule we have is you must use a non back flow device so that water from your fresh water tank can't flow back into the city water system, while your pumping water from the city into your trailer or truck.
Which is kinda silly also since the city water pressure is always higher than your fresh water tank pressure. But what they are concerned about is creating a vacuum after you stop pumping water into the tank, and the water being sucked back into the water line.
Still silly, with all due respect.
