Howdy-ho, Sports fans!!

Looking for info on toilets hoping someone might know.

Our 36 yr old toilet has about had it and I don't know if I want to replace just the valves and assemblies or the whole dang thing.....

questions....

1) Are they universal fit/seatings or brand specific?

2) Are there any brands/styles I should avoid?

3) What should I know before taking on this project?

Thanks, All.....!!!

The Newer porclean stools with foot valve are very reliable,,,, I personally have a Thetford model. and its been very reliable with no problems..

Hi Robert,

You don't specify what brand your unit is, so I'll just wing it here.  I have a Thetford 901 with a porcelain bowl and plastic base (1977).  Several years ago I had problems with the rim flush holes clogging and then a problem with the flush valve.  I have a bathroom sink adjacent to the toilet so I installed a heavy duty sink sprayer adjacent to the sink faucet and I use this to flush the toilet.  I installed a old fashioned faucet washer underneath the spray head and drilled a 3/16" hole in the middle of the spray head.  The washer covers all of the little holes and now the jet stream is like a Super Soaker (will shoot about 30').  The return spring on the water valve had broken so I attached a lever arm and weight to close the hemispherical dump valve.  If you try this be careful when tightening the spray head down on the washer (I cracked mine).   I've used it with this set up for about four years now and I think that it is better than new!  I use less than 1/2 cup of water to flush #1 and usually less than a cup for # 2.

Good Luck,

RWC

I have an older Thetford.  all plastic and pretty stained up.  I would rather just replace the whole unit.  I'm seeing a few in Craigslist in good shape for less than what a rebuild kit would cost.

But, the question still remains:  do these have a universal mounting or am I going to have to do lower pipe/tank conversions to fit something else?

99.9 %  of RV toilets are plug and play so to speak,  2 bolts, and seal. and attachment of the water line.

Well, now you've got me remembering!  My china bowl Thetford was actually out of my older RV (1971 Mini-Winnie).  I was using the older RV while I remodeled the newer one.  The toilet in the 1977 TQ was all plastic and although it was in good condition, I knew that it would not wear as well as porcelain; so I exchanged them.  What I remember about the plastic one was that there is a third tie down bolt that is accessed with a socket on a very long extension.  There is a removable plastic plug somewhere at the rear area below the seat.  I remember that I almost broke the toilet before realizing that there was another tie down. 
Hope this helps.

p.s. The newer one will probably have two bolts, and you may want to consider a rubber seal or at least one with an extension slightly into the toilet flange.

  Myself and the good wolf man answered a similar question a few days back if I recall?? 

  Ive replaced several toilets of different brands in many RV's, and all were a standard universal type fit down into the plastic floor flange. All had ONLY the two vertical flange "johnny" bolts/nuts and you also install a new soft rubber flange gasket/seal (should come with new toilet).

  Of course, you have to move the water line from the old to new toilet/location but the flexible polybutelyne or PEX tubing is so easy to deal with and any RV house has all the parts you need and they are generally NOT brand sensitive i.e. it dont matter what toilet you use, but you do need the correct fitting so the water line can attach to the new toilet.

 The new toilet should match the old height. The standard/regular height is if you have a raised platform on which the toilet sets and the so called "high rise" is for a toilet that mounts at floor level.

 My latest purchase was for a china bowl which I highly recommend and they weren't much more (if any) expensive. Mine is a Dometic but Dometic or Thetford is what Id use as parts are so readily available for either.

 Its NOT rocket science to install a new one, not to worry mate.

NOTE*******  It is very wise to EMPTY the waste tank Prior to changing the toilet, This said from prior experience. That way the wafe of the aroma isnt overwhelming.

  Yo Good Wolf Man, to add a bit to that)... Not only empty, but drain and flush n fill n drain n flush flush and then I refill and add some bleach then drain again. NOTE don't however add bleach to a black holding tank in the normal use and operation as it can react with some of the toilet chemicals we use.
