Someone else can find you a link. My memory says that
type of tubing is known for leaking. I'd get some
quotes on replacing all that tubing with some more
modern tubing. Pex might work better.

This master home inspector says he hasn't seen many polybutylene
failures in Utah, but they are common in some areas of the country.

He says one reason plumbers loved it was that only they had crimping
tools, so they would have to be called.

They changed from aluminum rings to copper and still had failures. They
changed from plastic fittings to copper and still had failures.

The plumbing industry decided polybutylene was no good. In fact, the
manifold system worked. It ran polybutylene from a central distribution
point, without tees or elbows. It was excluded from the lawsuit because
there was no trouble.

I see the manifold system uses threaded compression connections instead
of crimping.

It looks like the guy at the hardware store is right. Threaded
compression connections work with polybutylene.
