Leaky RO/DI canister

So I just recently replaced all the membranes and filters on my old Coralife RO/DI unit. I got all of the stuff including a flow regulator from Spectrapure. I am very happy with my purchase and it is like I have a whole new unit. The middle clear canister is leaking. At first it was just a drop or two and now it is a little worse. I took the unit down teflon taped it and that made it worse. I have unsrcrewed and screwed the thing back a half a dozen time thing maybe the carbon block wasn't seating right. I read somewhere to use vaseline on the threads, can any one confirm? Thanks in advance!

I would not use Vaseline. You would want to use a food grade Silicone Lubricant.

 

is there an o-ring in canister or on the unit itself? if so, may be bad, can buy replacements at lowes homedepot menards and the like

 

There is one on the Spectrapure canisters, and I think that would be the problem as well.

 

The O ring is on the inside of the container and doesn't seem to be pinched or cut. I will go to HD and check the o ring situation. Thanks

 

A little coating of silicone grease usually seals them up. You might check the sumps or canisters for hairline cracks, not always apparent but they do happen.
