My housings are standard 10 inch blue made by Ametek.
I am trying to put in replacement filters for my RO system, but I can not open the blue housings. I tried using a filter wrench to grip the housing body and then twisting the housing cap (lefty loosey, right tighty, correct?), but it just will not budge:madhell: . Am I doing something wrong, using the wrong tools, or is there some other way -- aside from smashing the housing or buying new housings?
TIA for your time and suggestions.

I'm assuming your incoming water to the filter is shut off...
Is there a pressure relief button on top of the filter?
Sometimes those standard filter wrenches do not have enough torque to loosen the housing. A strap wrench works great in those cases. They run about $8 at the hardware store.
Good luck.

Could you have tightened the filter housing with the wrench the last time you put it on?
To release pressure, shut off water coming into the filter and turn on a faucet till it runs dry.
Then take your filter wrench and put it on the filter as snuggly as possible. Take your left hand and firmly hold (anchor) the left-hand side of the pipe connected to the filter housing. Do not turn the filter wrench but impact it lightly with the heel of your right hand with short, sharp blows.
This will cause the filter to come off more easily without putting undue torque on the pipes by 'turning' it hard. You really don't want to jeapordize the integrity of the pipes.
I hope you don't have to cut it off.
When you go to put it back on, do not use the wrench. Hand tighten it making sure the o-ring is securely in place. Use silicone and not any petroleum product on o-rings and housing threads.
Hope this helped.

Is this RO under a sink? In the garage? In a crawl space?
As already stated, you have to shut off the water and release the pressure. If the RO is under a sink then the supply is likely a PE tube coming off a shut-off valve tied into a cold water valve. You can turn off the feed and open the faucet till the water stops. If there's a "T" and shutoff at the top of the storage tank then you can shut off the tank (saving the water) and open the faucet to release the pressure.
If your RO is mounted to a cabinet wall it will be easier and the best way is as Andy said, kind of a "shock & loosen" procedure. If the RO is free then it will be more difficult. BE VERY CAREFUL not to damage the connected tubing as Andy warned.
If the installer didn't mount the RO then maybe he/she had a heart and left enough tubing to pull the RO out in the open where you could slip a tube or something over the wrench to increase your leverage, get someone BIG to hold the RO and tap on the wrench. MAKE SURE YOU'RE TURNING IN THE CORRECT DIRECTION! Picture looking at the filter housing from the BOTTOM UP. Loosen will be counterclockwise.
When reassembling use a little "food grade" silicone on the o-ring and HAND-TIGHTEN. You can find it a Lowes under the GUNK brand in a little white plastic "tin" for about $4. To identify FOOD GRADE look for "NSF" on the container. If you don't see that logo then it's the wrong stuff.
Let us know how it goes
