If any of you are re-doing plumbing, and have the old gray polybutylene
pipe, I'd suggest replacing it all with PEX, if it's reasonably easy to
do. The polybutylene is good, and withstands freezing, but developes
little tiny holes when used with chlorinated water. PEX does not have
this problem. The chlorinated water was the reason the PB pipe was
discontinued in housing. RV plumbing has lasted much longer because of
the lower pressures and less exposure time, ie. not filled with water all
the time.
