house is copper, built in '62.
raised floors, crawl space.
sewer is cast iron, 3" main. pretty good condition, aside
from the ficus tree in the front yard that is in mortal peril
if it screws with my sewer main. i'm largely leaving it alone,
with the exception of a toto in wall toilet.
now, the copper.... not in very good condition. southern
calif water, never been a water softener on the house,
so, it's time to repipe. T's and couplings are weepy, with
lots of evidence of seepage.
1" feed from the meter, 3/4" copper from shutoff on the front
of the house.
now, the strategy.... i'm going to use a manifold for both hot
and cold water, located above and in front of the water heater,
not blocking it. individual 1/2" pex for each device, with a ball
valve on the manifold. pex and fittings are uphonor, with a
milwualkee pex tool for connection.
no tees or splices except at the manifold, and the connection
to the device. stubs thru the walls in copper.
now, the questions... should i put 1" pex instead of 3/4" to the
cold manifold? manifolds are 6 port, with 3/4" at one end, and 1"
at the other, so i can go either way.
i have 10 cold, and 8 hot taps on the manifolds. ball valves on
each tap, in case things don't go well. uphonor ball valves for
the shutoffs, seem to be made of unobtanium, judging by the
price.
as i was going to go under the house in 1", i want to run 1" all the
way thru the house underneath, out to the backyard. there is a pool,
and i want a full 1" to the pool fill.
so... the questions come to these:
3/4" or 1" to the cold manifold? hot obviously is 3/4" off the heater.
if i use an 18" flex connection to the water heater, can i go directly
to pex?
was going to use 1" brass schedule 40, cut and threaded, thru
the wall into the crawl space, then transition to pex inside.
is this acceptable?
this is really stupid to ask, but i don't know...
for the pex run to the pool fill, do i have to change to change to
pvc to run bedded in sand under the pavers around the pool, or
is pex legal in such a situation? i was going to use schedule 80 pvc,
but after looking at the pex, it seems pretty indestructible.
for gluing up domestic water in pvc, what's best? christie's red hot blue glue and
primer, or is there something better?
anyway, thanks for any feedback.
