Homes are now commonly plumbed with $\frac{1}{2}"$ crosslinked polyethylene $($PEX$)$ pipe rather than

copper. PEX is significantly cheaper $(20$x$)$ than copper and does not require heat or solder to

join. The water meter $($which measures the volume of water passing through when it enters the

house$)$ must be plumbed with $\frac{1}{2^{\text{'}\text{'}}}$ copper, and adapts from the incoming municipal service line,

which is $2"$ PVC$.$ Sewage exits the house along $2"$ ABS piping.

Create a list of pipe, fittings, and instrumentation required for plumbing a house with $1$ four$-$piece

bathroom, $1$ two$-$piece bathroom, a kitchen, and a laundry room, using PEX as the primary piping

material. $($Please$,$ answer what the question wants to see.. it asks that a list of pipe, fittings, and instrumentation required for $1$ four$-$piece bathroom, $1$ two$-$piece bathroom, a kitchen, and a laundry room. Could you please answer the question by each room$)$
