Mike, Great looking roof cleaning up there in West Chester,PA. The season is still young and you are already landing some very nice upscale homes! Looks like you are off to a great start this year!
Mike, what pumps are running? You are knocking out some monster homes and I would be going through 5850's like a Pez dispenser if I had to push my mix that high on a daily basis.
How long has your 5850 been running? Whenever I get on the ridge of a large one story (which is like shooting a two story from the gutter line), I hear the pump cycle like crazy. I use 5/8" hose and it might be building up to much column pressure. Thinking about switching to 1/2" lines.
