My problem is that instead of circulating the mixture out the top of the cell, into the reservior and returning back into the bottom of the cell, it also pushes some fluid/hydrogen out of the bottom hose of the cell which flows up into the bottom of the reservoir, filling it to overflowing, leaving the cell with almost no fluid in it.
Interesting - I don't think it is gravity (though it helps having the reservoir higher), it is increased pressure from the act of making the HHO. When the plates start producing HHO there is a pressure build up within the Dry Cell. This will let the pressure try and escape through any possible outlet (top and botom)
I am no expert, but you might like to do two things.
- Increase the diameter of the pipe going from the top of your cell
- Decrease the diameter of the pipe refilling the cell at the bottom
Whatever pressure is established will find it easier to go through the larger pipe at the top.
I did a bit of Googling for acid resistant one way valves but only found expensive pressure valves.
There are HHO One way valves made for the gas but I was not able to find any for the electrolyte.
My reservoir has always been higher with a small pipe to the cell and i have never had your problem.
Try changing the pipe diameters - let us know how you go.
PS - If you have a pic of your setup it could help
