Unable to change bulk reef supply rodi

[AC1211]

I am unable to unscrew my 200gpd rodi from bulk reef supply to change the filters. What should I do?

What part? Prefilters canister? Are you using the wrench? Is it mounted to a wall?
The membrane housing? Big channel locks or pipe wrench should do it.

What are you using to try to unscrew it? Strap wrenches are handy for stuff like this.

You could try a canister filter wrench: https://www.bulkreefsupply.com/wrench-for-reverse-osmosis-canister.html

Or an oil filter strap wrench will work too.

I am using the wrench provided and trying to get the sediment filter canister done. It is not mounted to a wall.

I also lubricate the O rings whenever I change anything, to help keep it from getting stuck the next time: https://www.bulkreefsupply.com/dow-111-o-ring-lubricant.html

That is what I have been using.

Mounting to the wall will help you get the leverage on there properly. Or try having someone else hold it while you wrench it. Sounds like it’s over tightened.

I put the wrench on it and tapped it with a hammer the first time. I didn't put them back that tight.

They can be really tough just keep at it and eventually it will loosen up .if it is mounted on the wall it is much easier

Unmounted creates a set of its own problems. NO leverage to work with.

yea I didn't have mine mounted and I had the hardest time unscrewing the carbon one. Had my wife sit on the bracket and I put their wrench as high as it could go. I eventually was able to loosen it. I am building a mixing station and will be mounting the RODI system to wall when I am done
