can we use flexible plastic pipes for water lines (hot and cold) inside a
and the second question concerns water flow.
the way the water pipes are right now in my house, one main (3/4 inch or so
thick) water line comes in the house. this splits in several places to go to
the water heater (for running water, the hot water boiler (for heating the
house) and cold drinking water.
from the water heater I have one pipe coming out and splitting in the
garage. on one side it goes in a water column for the bathrooms (on 2
levels) and on the other side it splits in a column for the kitchens.
all these pipes are usually 1/2 inch thick. the only one that's larger is
the main entrace one.
now, for some reasons, I want to change the lines that go to the upstairs
since all pipes eventually come in the same (1/2 inch) pipe at the water
heater, does it make a difference if I split the bathroom pipes upstairs and
take a new branch to the kitchen, or run a new pipe all the way down to the
basement to add another split close to the water heater? I'm thinking in
terms of water debit, if someone uses the bathroom and kitchen at the same
this would mean that two bathrooms and one kitchen areo n the same water
pipe, but eventually all pipes come in the same place anyway, so woul the
debit drop or stay the same regardless of where the pipes are split?
