How else do you know, other than when they overflow, that they are full?
You may be thinking of a pressure regulator for when you're connected to "city" or "shore" water. My Roadtrek
didn't come with one, so I bought one at a local RV Centre for around $15-$20. It keeps the potable water supply
from a campground tap from blowing up your plumbing with excess pressure when you're connected to it.
It's a flow through pressure valve that I can attach to the van's city water connector, and then attach a garden
hose to it. They have a male and female end and sometimes look like this (the one I have does).
If you're just filling your fresh water tank, you don't really need any kind of pressure sensor on the hose,
unless you can divert water from the city water connection to fill your fresh water tank. Roadtrek has a plumbing
valve setting/position that allows me to do that if I want. Or, there's a fresh tank fill hole in one of the door
frames for filling by a garden hose at home. When I fill that way, I just wait until it overflows, or I can listen for
it gurgling, or I can check on the monitor panel, so that I know when it's almost full.
Does that make sense?
