Hot water heater popoff valve

[Terry Neal]

Hi Bob,

On my PT40, the popoff valve for the water heater is fitted with an
adapter that is attached to a drain hose (think it's heater hose) that
fits through a hole in the floor of the compartment & drains into the
area behind the radiator in the engine compartment. Then if for any
reason the valve opens, all the hot water just sprays on to the ground.
Looks like it was plumbed this way at the factory. Yours must be a one
of a kind maybe? Sounds like you have a good solution now though.
