I’ll agree that it is always a good idea to pull the trigger as much as possible. When you’re not pulling the trigger the water circulates inside the pump and gets hot. The plungers and ceramic become very hot. When you pull the trigger cold water rushes in and cracks the ceramic plungers. For this reason, you should let water move through the pump pretty much all the time. Maybe setting the gun down for no more than 30 seconds at any point. Unless you’re using a re-circulatory tank system to avoid water heating up. But you’re not on these less than $3000 machines.
Using the machine for high-pressure will not hurt the pop, unless you’re using a high-pressure nozzle which has an orifice too small for your machine. Like trying to force 3 gallons a minute through a 2 GPM nozzle. That won’t work. But if you’re using the tips that came with the machine. Or the right ones in general, They’re made for high pressure and you won’t hurt it.
This assumes you’re talking about high pressure after the pump. Not high-pressure water coming in.
