I just ordered my new submersible pump and pvc drop pipe for 358’ foot well, but I’m still uncertain about number of check valves and placement. Supplier was recommending additional check valve after pump and then one every 200’. On this forum I’ve read discussions that advocate for using only the one that comes with pump. Should it be factored in that I’m pumping into storage tank @0 psi? The 42 year old pump I just pulled didn’t have any additional check valves. Should that count for something?
Thanks
