I just recently purchased a used Bay Hauler BH3360. The trailer is in immaculate shape, but there is very little info on it. The brochure for this model shows it has 80 gallons of fresh water capacity. And it has 2 freshwater fill points on the outside. I am trying to figure out how they are plumbed together to the pump, etc? And how they are plumbed to the freshwater drain? Basically, I am trying to figure out if they are connected together somehow, or how the pump draws water from one or the other?
Usually one connection is where you connect to provide water under pressure to the RV and the other is the place that just runs a pipe into the water tank to fill it.
Connect to one and see if it just flows into the water tank and the other should pressure up the faucets in the rv.
Some RV's, like our HR, have a valve also that will fill the tank when the outside water is connected to the presuure side.
Nope, we have had RV's for over 10 years of many shapes and sizes. But there is two separate fills that go to the two seperate water tanks. There is also a city water connection in addition to those two fill points (gravity fill ports). I am just trying to figure out how the pump gets water from one tank and the other, and what happens when one tank is empty? This is a toyhauler, so it carries alot of water.
On our previous motor home we had 2 tanks, each under the dinette seats. There was a hose at the very bottom of each tank that connected them, covered up buy a pice of wood running under the dinette, along the wall. I always filled the tank that was farthest upstream and did so slowly.
Hope this helps...

This is kind of the way I would imagine they are configured. Since I cannot see a three way valve at the pump with 2 lines going to it from the tanks, they have to be connected together at the bottom of the tanks, unless they have some creative way to switch from one tank to the other, or use some type of air lock system? I guess the real way to test this would be to fill one tank to the top with the other empty, verify this with the sensors, and then wait a day to see if one lowers, and the other raises???
