I have 4 BB housings for prefiltering 2 watersofteners. Every time I change out or clean the filters inside the housings I have problems wirh the o-rings not sealing correctly. I was told I need to use a special lubricant. The lubricant that dealers sell me in not cost effective. And it seams to not always stop the leaks. I am now using canola oil. it works great and does not cost a fortune. Is there a problem with using canola oil?
How do I order new o-rings if 2 of my housings have no information for model # or manufacture? All I can tell you is that the housings are 100% white. 20" X 4.5" size. The o-rings are a different size then the other blue housing units that I have.
