I "Hate" this forum, because we can't quote the post we are replying to.
But here goes. Guy Blackmon, the FloJet Pentaflex does NOT have a bypass built into it. That was a rumor that was spread brother, and it is untrue. It has a pressure sensing switch, like the Fat boy. However, unlike the fat boy, it's relay is encased in epoxy, underneath the pump. This means it is a bitch to fix, if the relay fukks up. Bob modifies them to use an external relay.
However, they can still fukk up, and the relay can stick in the OPEN position.
I hate when that happens Brother Guy, because that means the pump will continue to run, until the weakest link fails, and chlorine blows everywhere !
12 volt pumps are Hokey for a real roof cleaning company, and that is another reason why you will seldom see them on our trucks.
They are only there for back up.
LOL, you pressure washers crack me up, you guys really do. You will dedicate 90 percent of your trailers space to a pressure washing rig to clean 50 dollar driveways and sidewalks. Yet when I ask you to make space for a compressor and reliable air pump to clean 600 dollar roofs, you balk, and make excuses.
And, I am not talking 3/8 All Flow pumps with tiny 5 hp dual tank wheelbarrow compressors either.
That's OLD information.
Now, IS a 3/8 all flow pump with a small 5 hp Rigid dual tank wheelbarrow air compressor better then a Fat Boy or FloJet Pentaflex ?
As far as reliability goes, hell yes!
But as far as speed of cleaning a roof goes, or ability to shoot far, not really.
But what we are using is so much better, it isn't even close.
