Jerry,
I been researching backpack sprayers, but haven't used one yet. I
read somewhere that the models Solo currently sells have the capability to
attach the pump handle on the left or right side. They sell piston pump
models that go up to 90 psi or diaphragm pumps that go to 60 psi. The
piston pumps won't handle wettable powders/water dispensable granules
(many pesticides are WP/WDG) because the abrasiveness of the granules is
hard on the seals. The diaphragm pumps are supposed to work well with
WP/WDG but they don't put out as much pressure. Solo's are fairly cheap
sprayers but a disadvantage I've heard is that you can't hardly get the pumps
apart to maintain/replace any parts.
I think a long wand will help with a higher reach. Solo sells a 5ft.
wand. I've also learned SP systems sells even longer wands.
They sell a 66" brass wand and a 78" fiberglass wand. Although their
sprayers are more costly, their SP0 backpack sprayer is a diaphragm that has a
working pressure up to 80psi and a max pressure of 150psi. Their SP0
models also have a built in agitator that "stirs" the mix every time the lever
is pumped.
I still don't know for sure which way to go. Since I already have a
25 gallon electric sprayer, maybe all I need is a 3 gallon hand sprayer as a
companion. Or maybe a backpack sprayer would last so much longer, it would
be worth the extra cost. I need to make up my mind. Spring is right
around the corner.
