      I have Gerber toilets that were installed in the mid 80’s. I recently had problems with the tank internals not working properly on two of these toilets, so I bought a universal replacement kit. When I install the universal kit, the tank holds water fine, but the problem appears when I try flushing the toilet. Water starts leaking from the two bolts that hold the tank to the base. It almost seems that the water refilling the bowl from the tank is leaking from the rubber gasket between the two. Any advice? Is a universal kit compatible with this type of toilet or do I need a very specific part? THanks.

      the gerber close couple gasket is very thick the one that came with the kit is probably not thick enough

      When I put the bolts in the tank I put on the washer and put some stainles plumbers putty around washer and put a level on the tank and tighten it down, have you got the right washer between tank and bowl.Try this site. http://www.gerber.com
      Ask them for washer number.

      There ares several styles of “universal” tank gaskets. You’ll need one that is the right diameter and thickness for your toilet.
