Amazing set up. Ok makes sense. Is there a particular regulator you recommend.
What is your concern with pex ? I was planning on using pex on mine. Also how do you suggest i secure the fresh water lines to the sump ? Over the top and in ?
Im also confused on the amount of regulators/emitters i would need.
No particular regulator I would recommend. Just make sure whatever you get is of decent quality.
Securing is pretty simple. Try to avoid putting pressure or bends on quick disconnect fittings or they can leak. A simple pvc elbow to hold it in place is easy/cheap.
The regulator is just the one. It’s to set the pressure of the whole system.
The emitters are per tank. I can’t tell you how many to use but I would recommend only one until your confident with drip systems. They come in 1, 2, 4 GPH and pretty much any other if you search online so using only one emitter should be easy to do.
Decide how much water you want dripped per day, devide that by 24 and buy an emitter close-ish or precise to that flow. The whole system is pressurized. The emitters allow a certain GPH from that pressure. Example: 50 gallons per day / 24 = 2.08. A single emitter at 2 GPH will hit close enough.
