Identify the actual connections
Describe the toilet, shower or basin that uses the unit and provide its complete reference where available.
Why it matters
Parts, access and suitable work depend on the installed model. A photograph of a similar product cannot confirm interchangeability or justify connecting an additional fixture.
A useful distinction
Some units receive only relatively clean wastewater and others are designed for a toilet connection. That intended use is a model fact, so it should not be inferred from the word pump on a previous invoice.
