Evening all.

Its just occurred to me that I've got this RO unit which came with a freshwater tank a few years ago. Problem is... I've no idea what GPD it is... or anything about it for that matter! I haven't got a wrench so i can't get it open to see if there are any labels on the inside about what membranes it has in it.

Can someone advise me on what to do to get it up and running... or whether it looks usable?

Also, is the units GPD determined by the membranes or is it something else that determines that too? If I get 100gpd membranes then will it make it a 100gpd RO unit?

I will need a booster pump and tubing but beyond that im a bit unsure.

Thanks in advance!

Nice find, definitely usable.
All the filters will be scrape though as they will have dried out, so buy what ever membrane you want and buy a booster pump and flow restrictor to suit.

The filters are still full of water :) nevertheless i think they'll be pants after 3 years of sitting in stagnant water. Might try it out and see what happens.

Judging by your comment, am i ok to buy whichever rate GPD membrane i want, so long as the flow restrictor matches the membrane?

Cheers

I wouldn’t risk it, the pre filters need replacing after 6 months regardless of use.

Yes that’s correct, can you see any numbers on the flow restrictor? Or is it missing?

Good point :)

I don't see any numbers anywhere on it. I think the top canister might be another filter but I'm not sure. I haven't tried to open that top one yet.

Looking at the picture from the front, right bottom is sediment filter, middle is carbon block, left is a di pod wich is plumbed in last and the top tube is your membrane housing.
The flow restrictor goes behind the membrane and is about the size of your thumb.

Those brass valves aren’t standard and I wouldn’t use them. Also looks like the bypass valve is missing too

Good eyesight! I'm looking at the photo and struggling to spot the difference between pods.

The brass valve is just a Y valve to split the water from the tap in 2 directions. The person i got it from said he used it so that he could still use the tap while the filter was running. Must have had good pressure.

There isn't a flow restrictor so Ill get that on the shopping list. I may be asking for help with plumbing it later on  haha :)

Thanks all
