Flow restrictor??
 

I have a 3 stage coralife ro unit the biggest they go up to is a 50gpd and i just bought a 75 gpd filmtec membrane does this mean i need a flow restrictor? If so where would i get one and how do i hook it up?

You'll be fine with your current restrictor. FWIW you can replace the restrictor with a ball valve and dial it in with your TDS meter.

Im new to this stuff so forgive me where is the restrictor on my unit?

It's a small valve looking thing on the rejection line. After you put the new membrane in as long as your reading zero TDS you don't have to worry about it.

It'll look like this:

On that coralife unit, the flow restrictor is built into the little plastic L fitting that comes out for the waste line. I'm not sure you can put a new flow restrictor on that unit.

I took off the piece on the waste line is this the flow restrictor? Also this white box was hooked up to when i first got the unit i was wondering what this was for?

Bump

does anyone know?

That's the flow restrictor down inside there. I'm not sure what the box is. Mine didn't have that.

Ok id really like to know what that box is for it was hooked up to the blue hose (ro water) when i got it.

Can anyone tell me what the box is for? this is how it was hooked up

I think the box is the auto shut off valve, that kills water flow to the membrane when the product water line is shut off, like when using a float switch. That way it doesn't continuously run waste water down the drain.

I removed the original restrictor and got an inline one to match the membrane size from bulkreef when I replaced my membrane.

Coolfish is right. The box is an auto shut off valve.

Just to avoid confusion - we don't recommend this approach.

The flow restrictor shouldn't be "dialed in" using a TDS meter.

Again - we don't think this is a good approach.

Just buy a $4 flow restrictor matched to your new 75 gpd membrane. Will take you all of 15 seconds to install.
