Ever hear someone complain that no matter how they try they can't unscrew the housings on their RODI system? Maybe you've run into this as well. Assuming that you've relieved the water pressure already, I'll bet you a dollar that in most cases:
1. The housing orings have never been lubed, and
2. The housing was tightened with a wrench.

Remember that when you tighten the housing, the seal IS NOT made at the housing threads (so no need to wrap the threads in Teflon tape as we sometimes see). The seal is made by compressing the rubber oring. If you find you need more than just a slight little (less than 1/4 turn) help from a wrench to get a seal, then it's probably time to lube, or even replace the orings.

It's good practice, every time you change your filters, to:
1. Remove the orings
2. Wash (soap and water) and dry the orings
3. Lube the orings with food grade silicone grease (see the last item on this page: http://www.buckeyefieldsupply.com/showproducts.asp?Category=205&Sub=109

4. And then put the orings back into their positions.

If you do this you are much less likely to have issues with leaks and your housings will be much easier to remove/loosen.

Remember that you have one or more orings in the RO membrane housing lid as well. Follow the procedure described above with these orings as well. See our BFS-5128 Double wrench on this page: http://www.buckeyefieldsupply.com/showproducts.asp?Category=205&Sub=109 for help with removing stubborn RO membrane housing caps.
