Yes - the seals inside pumped Smart Valves are designed to only withstand a maximum of 1Bar of pressure vs the standard units which go up to 7Bar. It is a common misconception that the logic module inside the Smart Valve can be simply switched over to HP - this will only turn the pump off and does nothing for the seals inside the unit. Connecting a pumped Smart Valve to a high pressure water system will invalidate the warranty and could cause leaking which will not be covered.
