Okay PoA plumbers...

Curiosity has the best of me.

Go into any Commerical business and usually they have industrial toilets that could suck down a basketball.

But they also don't have tanks.

Why do houses generally still have tanks on toilets, other than these industrial things being hellaciously noisy?

Is there some Commercial higher water pressure thing I'm unaware of as a generally clueless plumbing non-aficionado, that makes these things possible?

Replacing flappers and chains and doodads seems relatively silly compared to just pushing the lever and watching whatever awfulness was trapped in any particular colon, go whooshing away.

:-)
 
Hellava question. I haven't a clue, but I'm betting $$ has a lot to do with it (although, under the right ( wrong?) circumstances it would be worth quite a bit....
 
We have some flushless urinals. They always get backed up and stink. I hate them.

Those are nasty.

Nah, I'm talking about the industrial whoosh makers you see in say, a McDs bathroom... if you dare go into one of those. Ha.

Do they need some sort of high pressure tank somewhere else? I don't think they do. But I don't know.
 
Gotta deliver a gallon or two of water quickly which means larger diameter plumbing than is used in a typical residential bathroom. Yes, the problem could be solved by using an accumulator in the bathroom. Instead people just use a tank and gravity.

If you have problems with toilet maintenance or performance just get a toto drake or drake II. The sanigloss finish is worth the few extra $$.
 
We had a Pressure assisted toilet. When the pressure vessel failed no replacement parts were available. We had to replace the whole toilet.
 
Love the sound of those rocket powered toilettes.... hang on to your tie when you flush....

Except in my house. Give me the 5 gallon per flush quiet toilet in my house.
 
Someone just mentioned it, and I'll confirm. When designing/sizing the plumbing layout of the pipe, the fixture unit "value" that you give the flush valve toilets is larger than the flush tank. Sure, you could put it into your house, but you'd have to up-size the piping that is providing water.
 
They are expensive

They require more mx then a simple flapper style tanked residential unit

Everyone in the house will hear it when you flush, kinda kills the atmosphere.

And it's a commercial toilet, for the same reason I don't have fluorescent lights in my house, I don't want a institutional corporate feel to my home.


Now in a business, where you may have the dregs of humanity coming in and launching god awful things out of god awful places in your restrooms, yeah, I'll take the stainless steel, warp speed toilet that has enough power to suck your soul out.

Ahhh that hits it. Bigger pipes. More flow. Got it.

Or worse, in my case, probably the pressure tank at the house entrance wouldn't be able to keep up with that anyway, coming in from the well.

Well anyway, was just curious. I guess those pipes running to those things do look pretty beefy.

Another item for the "if I ever build a custom house" list. Ha. At least one monster toilet for those days you know you shouldn't have eaten sketchy Mexican from the food truck... LOL!

I still remember high-tank toilets with the pull chain. They were still common when I was a child. They made a nice whoosh when you pulled the chain. Flushing twice was rarely necessary when you had one of those babies.

We also had water tanks (usually called "towers") on the roofs of all buildings that were higher than six stories, which is still the case in New York City. When I was a really little kid I got curious about them and snuck up onto the roof of a nearby apartment house to check one out. After staring at it and listening to it for a while, it dawned on me that it was just a bigger version of the flush tank with the chain that was used in the head.

I excitedly ran home to share my discovery with my mother, who promptly beat the **** out of me for being up on the roof. I guess she didn't share my enthusiasm for science.

You ever see a toilet in Australia? The out-pipe for lack of a better term is much larger than what you typically see here. I don't think a mere mortal man could clog one of those things.

Have to have somewhere for the dinner plate sized spiders to hide. ;)
 
Look up zurn pressure assististed toilets. 3 to 5 hundo...loud but will practically flush a redwood.
 
Hey I found a video of one.... and apparently they sell them in the US.


Now I'm wanting a new toilet...

When I was in Iraq (I was ATC in the Army) we built a state of the art control tower at COB Speicher, right outside of Tikrit.

The flusher they used for the crapper was the tank and pull chain type for the squat-over-the-hole-in-the-floor crappers. One of the girls pulled the chain and the damned thing came down on her head! That was in 2011.

The other thing about flush valve toilets (tankless) is that they normally use more water than residential tank toilets, so they don't meet code for residential installation, which is typically 1.6 gpf by most standards.

1.6 gpf standard ... 2 to 3 flushes required to achieve satisfactory results ... but don't argue with the standards - they're good for the environment! :)

I'm telling youse guys, Toto Drake toilets with sanigloss finish are the only way to go. No, they can't be bought at the orange or blue stores...that is a good thing actually.
 
These style toilets are also common in larger NYC apartment buildings. My mom's apartment (where I grew up) is on the 16th floor of a Manhattan building. Her toilets were the industrial style. When I was little they scared me - they flushed with gusto.

They were basically maintenance-free.
