Hey guys, I ran into a slight hiccup while hooking up 2 potable water tanks for my home.
One tank holds 600 gallons and the other 400 gallons. It was my thinking that because the 600 is taller that I needed a check valve on the 400 so that it does not over flow when both are filled due to the height of the water level on the 600 being 16" higher. Both tank outlets are plumbed together and lead to a main pump that supplies the house.
The problem that I'm having is that the 600 empties out all the way and the 400 remains filled, I was under the impression that when the water levels out in both tanks or is a little lower in the 600 that the valve should have been able to open letting water out and allowing both tanks to empty at an almost even rate.
The pump shuts off when the 600 is emptied because the float switch for the pump is in there. Below is a simple diagram of the water connections and the valve used.
The inlets have floats on them that shuts the water off when filled.
I currently have a spring type check valve in use and was under the impression that 10" or so of water should have had enough pressure to open the valve. The water level in the 400g tank is about 60-65" when filled.
Any ideas??
