Decided to try and upgrade my NextGen RO to a 2 post 4x40 in series system. Its basically a prefilter housing into a Procon Series 4 pump running on a 3/4hp motor.
With some help from fellow Maple Traders I came up with my plan on how I was going to proceed.
I bought a new SS housing from Amazon

and 2 new Dow XLE-4040 Membranes
https://www.amazon.com/gp/product/B0...51M99A6BKVGZNT
Overall the upgrade was not too difficult, after finding the correct position I wanted the new housing to be in on the dolly I drilled 4 holes for the supports.

and attached it.

Next came the plumbing. I wanted it to run in series so this is my only concern at this point with the whole setup. I got braided PVC hose to connect my concentrate from the 1st canister into the 2nd. The hose is rated for 200PSI, I generally run the RO at about 210-215psi. I know the hose can handle a bit more than its rated for and I certainly dont want to push it or risk any damage. Ive got my eye on potentially purchasing a steel braided 48" hose from McMaster-Carr https://www.mcmaster.com/flexible-braided-hose its about $115 plus shipping.

I want to clean up the permeate lines so that they look more symmetrical. they will connect to a T and dump into my permeate tank.
Lastly I will install the new filters tonight and run some distilled water through the system to rinse out the membranes, but I think I should be good to go.
If anyone see's any issues, please let me know.
Thanks!
