Click questions below to see answers to your Solo ® Backpack Sprayer questions

How far can I expect the sprayer to spray?

The sprayer will spray up to 25 feet.
What kind of oil or grease should I use on the o-rings and seals of my Solo ® sprayer?

DO NOT USE OIL. Use heavy grease or petroleum jelly on all o-rings and seals.
Can I spray water sealant through my sprayer?

Yes, most types of water sealant can be used with your Solo ® sprayer, but please consult your label for proper application methods.
Will the replacement straps you sell fit the Solo ® sprayer I bought 10 years ago?

Yes, the straps we currently sell will fit on older models.
I try to pump up my sprayer, but I can’t get any pressure. What now?

Check the valve plate and the o-ring at the valve seat. Replace if either is damaged.
I still can’t get any pressure. Any other suggestions?

If you have a piston pump, check to see if the collar or piston is worn, and replace if necessary. Also, if you have a deluxe sprayer, check the o-ring on the pressure regulator for damage, and replace if necessary.
How can I tell if I have a diaphragm or a piston pump on my sprayer?

Examine the pump housing at the base of the sprayer. If the housing consists of two circular pieces held together by 12 brass screws, it is a diaphragm pump. If the housing is a cylinder, it is a piston pump.
