But they can (and do) develop leaks.

Every added fitting introduces more potential for leaks.

My house PEX is ~ 21 years old and has never leaked. Less chances in a
home run to each water fixture from a manifold.

Tell that to the Paint Meister. He's the one that hates PEX.

I'll quote something he said in an earlier thread:

"PEX is for people who are too lazy to do REAL Plumbing. It's about the
same as running a garden hose to your sink, toilet, or whatever else. It
may seem durable and strong, but for how long? It's plastic, and like
all plastics, it has a limited life span. Some day in the future you'll
come home and find your house flooded because this plastic crap broke.

REAL PLUMBING is made from metal, and is a PIPE, not a HOSE!

But we live in a day and age when people worship plastics and dont want
to do any REAL work, or pay for REAL plumbing.

Pex is fine for a temporary means to get water from point A to point B,
but it's NOT a permanent plumbing. I might consider it for an outdoor
sprinkler system. but not for "piping" in my home. "

a realtive of rose my GF has a home, part of it has just a crawl space, frozen pipes every winter..

I went ahead and replace all the copper with PEX and sharkbites.

not a single leak or frozen water line in over 3 years.

although a PVC 4 inch trap has frozen a couple times...

so i want to put insulation board along all sides of the crawl space and insulation board on the dirt floor ........

then take a small run of flexibe ducting to warm the space in the winter.........

PEX rarely freezes, plastic doesnt conduct cold well, and if it does freeze, it expands but doesnt split like copper, if pex llllline freezes when it warms up, it juust shrinks and water flows again

PEX IS THE BEST THING SINCE SLICED BREAD
