I'm replacing much of the plumbing in this project, which has a kitchen and bath. I've removed the old air pressure tank, the hot water heater, the toilet, the broken black waste tank, and an arm load of supply lines and some abs.
In phase I to get things going i'll install a new plastic water tank (20 gal max.) a new 6 gal propane heater and an on demand 12 volt water pump.
Using the existing lav. , shower and kit sink I'll tie the waste together to a hose fitting to fill a portable tank or out on the sand, depending on location. Will use porta-potty instead of toilet for now so now tank there.
Will plumb all new supply lines with pex. (no problem there)
So here's my question:
The water storage fills with a hose from a cap to the exterior, but when all is empty, how does water get to the hot tank?
Do you have to turn on a hot valve for the pump to push it to the hot tank or does it just over flow there? How does it get past the pump?
I've looked at the diagram at the start of this section and that is exactly what I pictured for layout, but I don't see how the water gets from cold tank to hot with out some kind of pressure. May be obvious if I had it all in front of me but I don't yet.
Thanks much.
