Polybutylene plumbing, especially in its
newest configurations, has a lot going for
it: flexibility, cost, freeze resistance, user
convenience, and, we believe, dependability.
In light
of the lawsuits
that have
involved polybutylene
(PB)
plumbing systems,
our confidence
may
seem misplaced. But we think our confidence
is justified.
The reasons are simple. First, most
lawsuits have cited accessories in the PB
system rather than the PB itself. Second,
we've had few problems, except with the
fittings.
Since we began to install PB ten years
ago, we've learned to do some things better
and some things not at all. For
instance, we no longer run PB lines from
the curb to the house unless we slip the
line inside a PVC sleeve where it enters
the foundation.
