Of the components that were part of plumbing, the development of a reliable and trouble-free water closet posed the most problems. A number had been invented by the middle of the nineteenth century, but all had shortcomings. The most common complaints were that they were troublesome to flush and were easily clogged. Perhaps the most offensive of the lot was the pan water closet. It was so named for the waste-collecting sheet metal pan that was designed to close off and seal the bottom of the closet bowl. When the unit was flushed the pan tipped aside, opening the drain at the same time water rinsed the bowl and the pan. The operating mechanism was intricate and because of its location easily became fouled; it also required regular attention. The most serious deficiency common to nearly all toilets of the time was the poor seal they provided between the bathroom and the soil pipe that carried away waste.

I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
