150gpd Upgrade

[paulben]

Just brought a 150 gpd upgrade from RO-Man but no instructions question is :

do you fit the flow restrictor on waste of first or second membrane and  does pressure gauge measure pressure going into first membrane or do you measure pressure entering second membrane

if anyone has a pic that would be great

 

[Dave B]

Got a pic of yours mate?

Easier to tell you from a pic

I am sure there are a few bits on YouTube that show how to do this. If not RO -MAN should be able to email instructions

I can definitely answer the question with a pic as i built my own ro and understand them

Just need to know what I'm working with

The 2 waste pipes need to be connected together then the restrictor and flush valve

The 1 input from the pre filters also needs to be split to feed both membranes 

I'm not sure but from memory i am sure ro man have the membranes in series which is no good they need to be in parralel to work efficiently

The pressure gauge needs to be before both membranes 

This is just from memory of ro man though so @spruce may know different

Definitely needs to be in parralel though

Your right @Dave B. Need to run them parallel so those both do the same amount of work.

Got an email from ro/man says flow restrictor needs to be on last membrane in the series and should have sent a flow chart but when I tried opening attatchment only got pic of upgrade parts big help .

Your way sounds better as both membranes are working on fresh water and not water that's been dumped by first membrane Thanks for your help .

You may need to buy a couple more 1/4" JG t pieces.

Also if your adding a booster add it after pre filters

If you will only have the 2 membranes then 2 x 1/4" t pieces or y pieces which i personally prefer for no other reason than i like the look better is all you need to connect them in parralel

Shop around on ebay and get a couple of these
