 We have the FIX for the ongoing problems that face water haulers and septic tank operators during cold  weather operations!

Without a means of heating the discharge / inlet valves on a vacuum / water tank operation in sub freezing conditions, it becomes nearly impossible to operate a valve due to water freezing in the valve plates. Until now the only options were to use coolant, robbed from the engines cooling system and cab heaters, run the length of the truck body to heated jackets or by the introduction of open flame directed onto the valve from a torch!  UNTIL NOW!
