Discontinue use of tap in house (8)

'discontinue' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'use of tap in house' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
an anagram of 'use' is 'seu' which is present in the remaining letters.
'tap' could be 'h' (H for the hot tap) and 'h' is located in the answer.
The remaining letters 'pat' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
