Does my general liability cover water damage from my work?

Generally yes for damage to others' property caused by your work, through the completed-operations part of the policy. It does not cover redoing your own faulty work, and some policies narrow water damage, so read the forms.

Why do property managers want a waiver of subrogation?

If a leak you caused damages the building and the building's insurer pays, that insurer would normally come after you. A waiver on the manager's side of the deal and additional insured status on yours sort out who pays without litigation.

Is refrigerant handling a pollution exposure?

Insurers treat releases of refrigerant, fuel oil and similar substances as pollution, and standard general liability excludes most pollution claims. A contractors pollution policy fills the gap and is increasingly required on commercial work.
