> We haven’t talked about toilets but this much is true: they used to work well but the low-flow model is vastly inferior. Combined with low water pressure, toilets clog and break down, to the point that you always have to have a plunger nearby (this didn’t use to be the case). Folks, we know how to make toilets that work: they need lots of water. Your constant problems with flushing are not your fault!

My experience is exactly the opposite. After replacing an 80's era toilet with a modern one, it flushes much better (despite using a lot less water). Water pressure also doesn't effect toilet flushes (excluding commercial tankless toilets), it just effects how quickly the tank refills.

Yeah, the early low-flow toilets weren't all that great, but they definitely got better pretty quickly.

The author also advocates for hot water heaters that go up to 140 or 170; at 140 you'll scald in 5 seconds and at 170 you'll scald 'instantly': https://www.energyguide.com/library/EnergyLibraryTopic.asp?b...

Here's a similar chart, with some sourcing.

At 170F a person would get a second or third degree burn in half a second.

Right, but there are regulations limiting the size of the tank, and the toilet flush is obviously effected by the size of the tank.

No, modern tanks are set often higher and the toilet has better flow.

What matters is how high the water falls and at what rate not the overall volume of the flush.

Modern toilets that flush about 7-9 liters for a number 2 flush are considerably better than the older ones that whilst flush almost double the volume do it over a longer period of time.

Toilet flush is basically a push if you do it with more force as in the water displacement in a given time frame is higher it would flush better than a higher overall displacement over a longer duration.

The other upside of modern toilets is that if they do clog they don't overfill.

That said over a lifetime of 30 years using only water saving toilets I never seen one clog in a residence I've seen a few public ones already clogged but who knows what they tried to flush there.

If you having so much problems I would take a look at your plumbing or diet you so won't need to use half a roll of TP to wipe your ass.

Yeah the 1.28 gallon flush Niagra Flapperless at my old warehouse could flush a god damned rhinoceros. In a year of ~75 workers sharing two toilets they never failed us.
