AFAIK they are only used for testing toilets. I’m not sure I see them as being accurate simulations of…real life. But there must be some reason behind it…right?
I replaced my electric hot water heater last summer. The hard part was getting it in the house and up the stairs. I did have the advantage of having seen my dad and the facilities guys at work do plumbing, so I knew how to cut and sweat pipes. I do wish the people who designed these townhouses hadn’t thought it was a good idea to put the hot water heater and laundry stuff upstairs.
Great job - that is harder than putting in a toilet! I didn’t have to get the torch out… 
Congratulations! It sounds like it came out much better than the sequential thread titles suggested:
In Which Una Installs her own Toilet
I’m Underwater
A New Experience (Possible TMI)
I may just use this a sig.
Thank you for a delightful thread on a totally surprising topic!

It almost makes me want to forgive Congress for making us use toilets that use so little water that trying to design a gravity-flow toilet that can properly handle #2 is like trying to design a car that gets 200 miles per gallon at 65mph.
Aren’t there also electric-assist toilets for those of us whose homes don’t have enough water pressure for pressure assist?
