Goooood night those RO canisters are stuck

[crewdawg1981]

Changing out my filters today and man o man were those things on there?! I had to break out the rubber mallet, hold the canister down and have the woman tap the canister wrench to loosen each.

I see that there is some grease on the threads already... should I be adding something else?! I assume its deposits from the water that are cementing these canisters together.

Swwweeet jebus my shoulder hurts now...

Not being critical but I just hand tighten every time (like an oil filter on a car) and never had an issue. Maybe i've just been lucky????

Yep, and a nice coat of lube on the o ring, and you are good to go.

Haha!

I was like... "what the..."

I do hand tighten and then turn on the system... if they leak then I use the wrench to tighten them little by little.

I hand tighten and then turn with the wrench until it gets difficult. That's my stopping point

They can kind of seize up a bit. I only hand tighten and that has happened to me as well.

A nice thing to have in the fish tool chest is a pair of those rubber gloves you wash dishes/clean bathrooms with. You'd be amazed how it improves your grip strength with things like threaded PVC, pulling vinyl tubes off barbed fittings, and RO canisters.

Also, Ace Hardwae sells a lube that is 90% silicone, and is great for o-rings on calcium reactors, media reactors, unions, anything that has an o-ring/rubber seal. Can prevent leaks, and is also useful for hose/barb connections. A little on the inside of the hose and on the barb makes it go on easier and a lot easier to remove.

Mine were the same on AWI unit, its crazy isnt it...I even broke one the cannisters way back on my older RODI unit when trying to get them off

Well, I'm glad I'm not the only one that has problems with these things.

I'll have to run up to the hardware store at some point and get some of that lube you mentioned Dave.

Here's a pic of the Ace Hardware product. It is made to be used with potable water, and it is waterproof, so it stays where you put it. You should not have to use this lube with RO cannister o-rings. I haven't, at least. It makes water tight seals where they might otherwise leak, like in a slightly imperfect seal in a calcium reactor lid.
