    Hello, can you convert your regular tolet to a tankless tolet?
    Thank you , York

    You DO NOT. There is no way to make that conversion. And, since "tankless toilets" need a lot of water, your tank toilet does not have an adequate supply line to install a "new" tankless toilet either.

    You know.....I considered taking a urinal adapter with the bolt slots and the 2" fip outlet and reducing the outlet to 1". To this 1" reduction pipe it through a vaccum breaker and finally to a 1" 80 psi water line. using a spud gasket and bolts attach this to a regular toilet bowl that would be used with a tank.

    To use it just manually turn the 1" ballvalve on until the toilet flushes to your satisfaction. LOL

    So think it would work?

    Also heres an idea I wanted to run past you. Have you ever seen a toilet tank made out of a 5 gallon bucket? All the holes are drilled with a regular bit or a hole saw. Mount the parts in the bucket and bolt it up to a toilet bowl.

    Ever seen anything like that?

    Toilets on submarines are flushed with manually operated ball valves (both supply and outlet), works great.

    Seems to me this thread has gone into the "tolet". The only real answer to the original question was given by HJ. No, you can't convert a regular toilet to tankless. Tankless toilets require a large supply line that will furnish the necessary water for the flush since there is no storage capacity. The submarine analogy is interesting, but hardly applies to a home and probably not to a commercial facility either.

    If you replaced the toilet and have large enough supply lines, yes, you could use a tankless toilet. You could possibly also use a wall-hung toilet with a tank in the wall, or if you like Rube Goldberg, you could put in a big bladder tank somewhere with a 1" outlet and supply that to the toilet. Might work.

    The limiting factor is of course, the size of the supply line. Residential homes do not usually have supply lines sized large enough, and retro fitting would be a very expensive proposition.

    Some of the towns around where I live figure your water base charge on the size of the supply line. One condominium I'm aware of was built with sprinklers, designed around 2" pipes! As a result, the complex is charged a significantly larger base price (before they actually use any water) for the potential demand. Many homes do not require such a large supply, but all tankless toilets require a large volume of water instantly. As said, if you installed something like a well water storage tank that had at least a 1" outlet, and ran that to the toilet, it would have enough volume to flush the toilet...lots of trouble for minimal gain. A good gravity flush toilet will work as well, and if you're looking for a wall-hung, that's not a problem. But, the bowl must be designed for the supply.

    Yeah here its basically the same way. The minimum monthly bill for a 5/8" meter is cheaper than the minimum bill for a 1" water meter. They charge a premium for the 1" meter and above.

    The ball valve is full port 4", so you can really plug that bad boy! We used globe valves, though, not ball valves, to run some flushing water.

    Sounds like something you heard about but never actually saw. Unless it was an "oval" bucket, you would have to work around the bucket to sit on whatever part of the seat that was till visible.

    I have it in my garage. It's an everyday 5 gal bucket. The bucket takes the place of the tank.....it does not block any part of the seat.

    Maybe I'll post it.

    Well, since a 5gallon bucket has about a 6" radius and a tank opening is about 3" back from its front, that extra 3" has to come from somewhere.
