I'm building a little pond [8x12 or so] & have been toying with the idea of making a geyser adjacent to it. It doesn't have to be huge and dramatic- a 1 foot spurt/gurgle every minute or two would make me happy.
I'd like to hook it into a branch line off the same pump that will be filtering/circulating the water. It is a 2000gph, low pressure, pump. Pipe will be 1 1/2" PVC. [is there any way to calculate water pressure when all you know is it will push 16' of head and the top rating is 2050gph?]
I was thinking of a very low pressure pressure-relief-valve- but then realized that the pressure would be fairly steady. So I need to figure out some [simple] way of gradually increasing pressure on an isolated line, then releasing it.
Or should I just go with a separate little pump and a timer?
Thanks, Jim
