Waterfall Pump Question

[Jg13]

I’m new here and hoping someone can help me out. I’ve never had good luck with the pump for our waterfall. It’s connected behind the waterfall, something like 30 feet away.

I haven’t messed with it all summer and went to turn it on. The pump works but there is no water and it’s dry. It did work at some point last year and I honestly don’t remember how I fixed it. The o ring should be good. I have some grease I was going to put on it, but I figured it was something to do with the valves.

Looking at the plumbing for the pool side, I wasn’t sure if there is something I need to change there , or if it’s the plumbing /valves near the pump.

Can someone explain to me how the valves and plumbing work on this picture? Or how should it be working?

Thanks!

Hi, welcome to TFP!
Right now the valves are closed. Using this illustration for reference: Pool Parts & Supplies | Pool Pumps, Filters, Heaters & Cleaners Plumbing and Valves - Jandy 2-Way: Pool School by PoolPlaza Pool Supplies Pool Plaza

Thank you! I tried looking up the specific valves to see how they worked but it was more difficult than I expected. That diagram was perfect.

I’m going to adjust the valves and then prime it.

I appreciate it
