A method of installing a container of flowable material in a counter below an access hole, the container having a first deformable portion in flow communication with a second deformable portion, said first deformable portion defining a first cavity, having flowable material therein and having a sealable first cavity inlet and the first cavity inlet being sealed, wherein the sealable first cavity inlet is sealed with a pump, the method comprising the steps of:
- feeding the second deformable portion having substantially no flowable material therein through the access hole;
- urging the flowable material in the first deformable portion into the second deformable portion;
- and
- feeding the first deformable portion having substantially no flowable material therein into the access hole such that the pump sealing the first cavity inlet is positioned in the access hole, and the pump is in flow communication with the container.
