Patience

I look as I sit
At a radiator valve
And the pipe that's connected to it
At the cold water feed
With a valve that is red
And the shower that is fed
As water flows through it
And the waste from the bath
Through a two-inch tube
Runs next to the hot water feed
And the rad' on the wall
Is two feet tall
But it's warm so there isn't a need
The taps and the shower are closed
Through the waste nothing presently flows
Its all in the plumbing
Though nothing is coming
And I look as I sit
At a radiator valve
And the pipe that's connected to it
