What is wrong if after replacing 3 sections of the cold water supply the toilet and tub don't get cold water pressure upstairs but the sinks and shower are fine and they're all on the same line?

Depending on the distance the pipe runs 3/4 inch pipe should be supplied to the Plumbing location with 1/2 inch lines branched off to individual fixtures. I have also seen incidents where to much solder could cause restrictions,and even break off inside the pipes and clog shutoff valves and plumbing fixtures.

What causes one bathroom upstairs to have very little water pressure in the shower and bathtub but the other bathroom has plenty?
Insufficient water pressure or incorrect pipe sizing
The water pressure in your upstairs bathroom is getting low you took the aerators of the sinks and found a white sentiment buildup on it you also removed the cartridges from your shower valve and also?
When the water pressure in your upstairs bathroom is getting low and you find a white sediment buildup in the aerator of the sink, it is the most likely cause of low pressure. You can also find the buildup in other fixtures including the shower valve and cartridges. Cleaning the sediment from the parts helps restore pressure.
The hot water pressure in the shower is still low after replacing the valve stem and seat?
Open up the actual shower head and remove the factory fitted restrictor.
Why does a ground level kitchen sink back up when the upstairs shower is turned on?
There is a clog between the sink and the line to the street or septic tank. The sink is the easier path for the upstairs shower.
Why would there be great water pressure in an upstairs bath tub and almost no pressure in the adjacent shower when both use the same access pipe from the basement?
Remove the shower head on the shower and see if it is plugged. Run the water with the shower head off and see if the pressure is better. Depending on where you live there may be a water saving feature on the shower head (mandated by law) for water consevation. Low flow shower heads often have a restricter in them. Delta has a brass washer with a very tiny hole in it and Moen has a rubber plug with 3 small holes in it.
How do I replace a showerhead?
Replacing an old or unwanted shower head is usually as easy as unscrewing the current head and replacing it with your new shower head. Simply screw the new shower head on and tighten it with pliers.
Why does downstairs shower drip but ONLY when the upstairs shower is used?
the pies are connected so when you turn on the shower the vaulve in the pipe going to the other shower might not be all the way closed thus causing it to leak
Why is the hot water pressure at the shower still low after replacing the valve stem and seat?
It is possible that a piece of the rubber washer or some material has slightly plugged it in the diverter.
Why does a shower curtain move towards you when you take a shower?

What causes a water pressure drop in the shower when someone turns another faucet on?
If you assume that the water entering your house in the mains pipe is at a constant pressure (this is a relatively good assumption) then the more outlets you give for it to flow from, the lower the flow rate from each one. Say you are supplied 1 litre per second and your shower is using all of this. Now, turn a tap on to 0.3 litres per second and there is 0.7 litres per second coming from the shower head. Showers are often upstairs and kitchens downstairs, so if the tap in question is in the kitchen then the effect will be greater than if they were both on level. The pressure of the water in the kitchen tap is made larger by the head of water pushing down from upstairs, and when both are turned on, the kitchen tap can "steal" more of the shower's water than a bathroom tap would when twisted the same amount.
Why does your upstairs toilet and drains gurgle and back up when your down stairs shower and toilet work just fine?
The drain is plugged somewhat between the upstairs and downstairs. Need to snake the drains.
What kind of drainage do you need for a downstairs shower?
Same as upstairs BUT LESS drainage piping BUT more vent piping.
