There’s nothing like some urine in the heating system.

A British plumber was fined and given a community service order Tuesday after being captured on hidden cameras urinating into a vase in a customer’s attic and pouring the contents into the central heating system.

Roy Williams, 47, was caught in the act urinating into a vase, poured the urine into the hot water tank and rinsed the vase in the cold water tank.

The plumber denied the charges, claiming he had a medical condition which meant he needed the toilet regularly and had been overcome by the sound of running water.
