no
What is the main source to be poisoned by lead?
The main sources of lead poisoning remain the same: lead paint in homes prior to 1978a , and lead pipes in older homes. Lead paint can be painted over (watch the sanding) and water can be tested for lead concentrations, in which case plumbing can be replaced or a whole-house water filter installed (reverse osmosis would be best).
What conclusion do you get from the observation that a fountain of water is created at the leaking joint of pipes of the main water supply line?

Which are the materials or metals used for making pipe?
Before copper and plastic pipes became available people used to use lead, iron or steel to make water pipes. Nowadays main water supply pipes for fresh water coming into buildings are made of plastic and pipes within buildings - delivering water to sinks, baths, showers and toilets - are made either of copper or plastic. Within buildings, pipes which take away waste water - which are also called drainage pipes - are usually made of plastic. Outside buildings, modern drainage pipes are mostly made of plastic but older drain pipes may be made of glazed earthenware (which is baked clay) or iron.

How can you improve the water pressure in your shower and you have replaced the Delta cartridge and removed the shower head to clear any obstructions and even shut off all water supply to remove air?
If the water pressure is fine in the rest of your house. The supply pipes are either too small for how many fixtures they serve/the shower's distance from the main. However, more than likely you have galvanized pipes that are corroded and they need to be replaced with copper or pex.
Why required Plumbing Parts?
Water Supply: Plumbing materials such as pipes, valves, and fittings are essential for the distribution of clean and safe water to various parts of a building. These materials ensure that water flows efficiently from the main water source to faucets, showers, toilets, and other plumbing fixtures.
Why are pipes insulated?
To protect them from frost damage. In cold weather, 'standing' water in cold pipes can freeze if the temperature drops low enough. When water turns to ice, it expands - which could cause the pipe to burst. However - you wouldn't know if it had burst until the ice had thawed !
