Thanks for explaining that QA. I was thinking "head" or lift involved the distance upward from the pump, regardless of where the pump was.

There is some restriction in my system as the nozzle only has one port, which is why it sprays so far. Hopefully I'm not over burdening the pump with back pressure.
