    Default Reviews and critique for homemade ro

    I have pieced together the RO. No bells and whistles to it. I would love to hear back some thoughts and tips to improve it or just glaring errors you may see.

    I still want to add a flowmeter to recirc and change out 1hp pump to 2hp. Just curious on everyone's honest thoughts.

    Is that PVC rated for high pressure? 250-ish psi?

    1/2 is up to 600 psi
    3/4 is up to 480 psi
    Fittings are suppose to share rating if properly welded.

    To be honest that's my biggest fear. I would like to add a low psi switch before I glue it all up.

    330 with a 1hp. Wouldn't mind getting a 2hp to replace it. It did the job with 1 membrane but with 3???

    I ran 2 4x40's on a PC 330 on 1 1/2 HP the last 2 years. I'm lookin for a 2 1/2 or 3 hp 220V and upgrading to 660 Procon. I just got 2 new vessels in this morning, $79 & free shipping on Amazon right now, 3/4" feed ports and they come with the hangers.

    When I upgraded from the single post and gas motor, I ordered all 3/4" & 1/2" stainless, that chinese stuff sucks, it leaked like a sieve and I swapped out about half of it with Schedule 80 PVC- elbows & tees.

    You don't need a flow meter on your recirc line, just one for permeate and one for concentrate. I thought about putting on on the recirc circuit, but guys on here talked me out of it.

    Keep up the good work!!

    Mind giving your reasons for sch 80 vs 40? And did your 330 not do the job or are you looking for more flow to maintain membranes longer?

    Cj, do you have a feed pump running to your PC or do you have enough head pressure?

    Good deal. Did you end up taking it for a maiden voyage? I like the the PVC idea but glad to see you added the coupling for breaking the system down. Definitely curious to see how you end up with for a concentrate % on your first pass
