I replaced the cell and housing on my RJ Classic SWG. When I placed it back on the pool plumbing it leaks slightly from the inside of the nuts on the inflow and outflow barrels. I have had the SWG for over five years and have taken it off many times to clean the element. I have talked to CircuPool and followed their limited instructions and I have changed the o-rings and used silicone lubricant. But the problem persists.
