Toilet Bowl Seal:
If your toilet bowl does not hold water for an extended period of time it means
that the seal is not working properly. If you have been using your RV for some
time (i.e. two plus years full time), there is probably a build-up of hardened
waste deposits on the rubber seal. The repair is surprisingly simple and easy
to do. All you need is Phillips and flat blade screwdrivers.
The toilet is comprised of three primary pieces: the bowl and seat, the
pedestal with water flush valve, and two wide rubber/synthetic gaskets
mounted between them. If the seal has been damaged it will need to be
replaced. This is unlikely however. All that is needed is a good gasket
cleaning to remove the crusted waste deposits on the seals. Though not a
pleasant job, it can be easily taken care of:
• Turn OFF the toilet water supply.
• Remove the plastic skirt around the pedestal accessible from the rear using
the flat blade screwdriver.
• Loosen the wide stainless steel clamp that captures the "C" rings which
secure the bowl to the pedestal
• Lift off the toilet bowl and put it off to the side. Depending on the length of
water hose that runs between the water valve at the foot pedal, you may need
to loosed the hose clamp securing the water supply to the bowl.
• Separate the two wide gaskets that located between the bowl and pedestal
and clean. Be careful not to damage the gaskets when cleaning. I found the
edge of the screwdriver blade was sufficiently sharp to break and remove the
crusted residue which has been causing water seepage past the seal. Clean
the gaskets thoroughly.
• Clean the throw valve which the pedal operates during the "flush" cycle.
• Clean the water intake ports on the pedestal if there is any hard water build-
up.
• Clean the pedestal top and bottom of the bowl mating surfaces.
• Reinstall all items in the reverse order aligning seals and bowl with the post
"key" on the pedestal, making sure that the hole in the gaskets align with the
water supply port in the pedestal. Do not overtighten the stainless steel clamp
as it will hinder the proper return of the closing foot valve.
