Fluid Leak at Slide-Out Reservoir

I'm experiencing an oil leak at the base of my 5th wheel slide-out reservoir. It appears even without moving the "Slide" in or out. Has anyone had this problem or know how to fix the leak?
  • When mine leaked, I found out the fittings were loose, was not leaking from the fluid tank as it appeared to be.
  • I have this problem as well. Trying to limp it along till the season is over. Then I will get time to fix it properly. Sure is making a mess on the bottom of the trailer though.
  • My sister had the same leak with her trailer. Ordered a new fluid tank with o-ring and replaced both.

    Only reservations I have using any silicone sealer is the next time it happens you have to remove all the silicone in addition to replacing the o-ring and without using silicone you can fill and use as soon as you're finished.
  • I just fixed the same problem on my fiver. Just do a search on the RV message boards for the details. Basically remove tank and clean it out good; check o-ring and replace if needed (my looked good -- so reused it); put a bead of Permatex RTV silicone around the oring and around inside seal area of the tank and put back together. IMPORTANT: let set at least 36 hrs before filling with fluid. Good Luck
