Ridiculous question about reverse osmosis

[andylee]

How do you unscrew the cap from membrane canister to change it? I mean specifically. I've taken it off the bracket; I've tried using an adjustable strap wrench, having my kids hold one end while I twist and scream at the to of my lungs. Any suggestions before I give up and order a new one?

With one of these http://www.bulkreefsupply.com/store...d-clips/wrench-for-standard-10-canisters.html

I've got those. This is for the membrane housing.

I think you also need to open up the out put valve, where the final water comes out, and let the system run out of water. At that point, with the wrench that was posted above, you should be able to remove the top.

Once you get it open the real hard part, at least for me, was removing the membrane.

Thats not the wrench for the membrane. If you have turn very hard you could be pressing the 2 plastics together and it can be hard to get off try not to squeeze them together.

Ahhh my bad for mis-reading. Try soaking the end that opens in hot water for few a minutes? Did the trick for me when I was swapping mine out. Think I had a large channel lock pliers nearby too when I was replacing mine.

 

[NewfiDog]

Yeah make sure theres no water pressure on it.

 

[marrone]

I think once the pressure is off of it that you should be able to open it by hand. Like I posted, the bigger problem I had was removing the membrane. I needed to use pliers to remove it.

 

[andylee]

I've already disconnected it, so no pressure. I will try the hot water tonight. I think the membrane can be pulled out with needle nose pliers once that housing is open (assuming that's I get that far).

Make sure you own a brand of RO/DI filters that accommodate replaceable membranes. There are some out there that cannot be changed and require replacing the entire canister with a new membrane. If yours is supposed to be replaceable, then the hot water trick should work.
