And what about those other, less regular jobs?

  Less regular jobs – Blocked sinks, drains, toilets

You need a rubber plunger for blocked drains or toilets or sinks. Sometimes it just takes vigorous pumping with a plunger to clear a blockage. If a blockage persists use drain cleaner. If the problem still persists, notify your property manager so we can call a plumber before there is any damage.
