Let an agent handle taps by type, installation, water quality, efficiency and repair.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Let an agent handle taps by type, installation, water quality, efficiency and repair.
A valve that controls the release of water or other liquid from a pipe or container, such as kitchen and bathroom taps (faucets), mixer taps, pot fillers and outdoor taps.
What it is for: Drawing water for drinking, cooking, washing and cleaning.
It can be install and replace it; fix drips and leaks; save water with aerators; check drinking water safety.
