Accumulator tank pressure??

I'm putting together a high pressure aeroponics system and having a difficult time finding info on accumulator tank pressure.

My question is what PSI should I pressure my bladder tank to if I plan to maintain aprx 80 psi to my misters?

I've seen some say 2-3 PSI below the pumps turn ON pressure and others say 2-3 PSI under the pumps turn OFF pressure. I'd appreciate some solid info on this if anyone could shed some light. Thanks!

Its been a while since I did HPA, but Im pretty sure its the lower, cut on pressure.

2 PSI below the pump cut ON pressure.

Get a thermal expansion tank from a plumbing store, they go up to 150 PSI for some model.

When I did HPA I ran at 120psi at the accumulator and then used a pressure-reducing valve to set my actual pressure before the solenoids. I found running too close to cutoff caused weird issues, so it was easier to run higher and have that extra pressure buffer.

Remember to adjust your automatic shut off switch on your pump. I think they are shipped out topping at 40 or 60 psi so if you want more than that there is a hex screw you turn clockwise to increase psi cut off

Yup definitely 2 below cut ON pressure
