User questions & answers

Question:	hi, does this come complete with a harness
Answer:	Yes, this comes with the "backpack like" harness. If you search online for images of "Solo 425", some pictures will show you the harness.
Question:	Can this be used inside
Answer:	Yes. I think people have applied stains with it. Be sure to wear appropriate PPE whenever using a sprayer inside.
Question:	Can I use this sprayer for water based sealer for my paver driveway
Answer:	Yes, have used it for that a few times. Just clean out when done.
Question:	Can use it to stain wooden fence
Answer:	I don't know since I use the sprayer for landscaping purposes. The question might be answered by reading the stain manufacturer's information sheet regarding the use of a paint sprayer - which a completely different piece of equipment than this Solo backpack sprayer which is made to use with disinfectants, fertilizers, herbicides and pesticides . Also are you going to use water base or oil base stain, a translucent or an opaque stain? Each has a different application method. Water base stain is usually running and are "wipe" off meaning you apply the stain, allow it to penetrate the wood then wipe off the excess before it dries, opaque stains are more similar to paint in that they sit on the surface of the wood and are usually not wiped off, etc... oil versus water gives you may other differences of application and clean up. I suggest you try googling for best sprayers for staining a fence and see what they recommend. Good Luck.

User questions & answers

Question:	Country of origin
Answer:	Yes indeed. On the drum panel that is opposite the door, there is an aerator. When you turn the drum so that the aerator vent is pointed down, the 'compost tea' will drip out.
Question:	Will the diaphragm last longer than the piston pump? My piston pump leaks all the time
Answer:	No problems here. If the panels came apart soon after purchase, may be defective. Check w/ amazon or seller for warranty info to resolve.
Question:	Does this 475-B come with a back strap with a waist belt
Answer:	I can’t remember exactly when I bought my Mantis composter, but more than a year ago, and it’s still going strong.
Question:	How long is warranted
Answer:	Each time you add more compostables to a compost bin, it restarts the composting clock. We recommend that you load in all the organic green and brown compostable material you can, then let it cook. Give it a few turns daily. In several weeks you'll have finished compost.

User questions & answers

Question:	Which pump is better the piston or diaphragm, I plan on using to dispense a liquid
Answer:	That's my model. If you bought this, did it fit?
Question:	can I returned this item
Answer:	Sorry I'm not familiar with that brand.... Mine was a Stanley.
Question:	Can I use bleach in this sprayer
Answer:	You need to measure the hose size ( ID internal diameter) of your Chapin sprayer. Most sprayers, Solo, Stihl, etc use 3/8" diameter hose. This wand has a stepped hose barb connection to accommodate 1/4" and 3/8" ID tubing. This range should cover almost all sprayers. Do not forget to purchase a replacement hose clamp.
Question:	What runs the pistons or diaphragm? Gas or battery
Answer:	Your sprayer has a 3/8" hose according to the Amazon script. My wand has a universal connector from 3/16" to 3/8", so yours should be compatible. I believe that you can get replacement connectors from Solo .

User questions & answers

Question:	Can I use organic stuff in this? I would need to remove the filters
Answer:	My best guess is that anything beyond a liquid mixture would clog the spray tips, which is why the filter (on the intake "straw" in the tank is there to prevent). If the organic mixture is completely liquid, I cannot see why the filters would need to be removed. Hope this helps somewhat.
Question:	what kind of warranty does it come with
Answer:	According to Mfg. the warranty is one year on parts and lifetime on tank.
Question:	Can you use this to apply stain to a fence
Answer:	Sure you can, but to use this sprayer for fence stain, you must have a LOT of fence. I would opt for a I gallon hand held sprayer that could be cleaned out more easily.
Question:	I opened the tank and removed the basket but there is no adjustment knob for pressure? Am I missing something
Answer:	After removing the basket, directly under it is the black pressure valve. It has 4 triangular pointers on it. I believe you press down and twist to one of the other positions.

Question:	will it work for Organic fertilizers? Using Fertilizers that have some tiny solids
Answer:	I haven't used it for organic fertilizers but as long as the solids are soluble in water, it should work. If they are not soluble, they will likely clog up the spray head.

User questions & answers

Question:	Will this sprayer handle mixed cleaning chemicals for pre-treating a wood deck? Speciffically "Restore-a-Deck" power mix
Answer:	This sprayer would work, make to clean well after use.
Question:	I need to spray for termites up on my 2nd story eves. how far or how high can this spray
Answer:	I use a wide spray setting to shoot weeds on the ground, and usually hold the nozzle about 10 inches from what I am spraying. I imagine the nozzle can be adjusted to shoot a thin stream too, but I can't speak to how far it would shoot. I'd be careful about over-spray or splatter if I shot up into the air. You might do better using a ladder and getting closer.
Question:	Is there a foaming tip available for this sprayer
Answer:	Solo offers their 456f sprayer if you are working with foaming chemicals. For me their no-drift nozzle works well for getting herbicides to cling longer to the plant. Hope that helps. Solo also offers a kit of various nozzles for @20 bucks.
Question:	Is this sprayer acetone resistant for applying paver sealer that has a water like viscosity
Answer:	Do not use gasoline, acid, caustic or potentially injurious chemicals. The sprayer will come with Viton seals. This would be designed to be used with AG or household chemicals.

User questions & answers

Question:	which vertical distance cover
Answer:	I do not know how long the warranty is good for, ask Amazon. I do know that I have had this sprayer for three years with no problems. As long as you don't leave spray liquid sitting in it for long periods of time and clean it well you should be able to use it for years. This sprayer is one of the best I have EVER used and I am a commercial grower and been in the business since the early eighties.
Question:	I noticed the ad includes buying a harness strap with the item. Does this mean the sprayer backpack has no straps
Answer:	Since there are metal parts, probably not.
Question:	how is the pressure developed for this product? Is the lever I see on the side moved back and forth to pressurize the tank
Answer:	WD40 is okay, but if you put some lightweight oil in and it will last and lubricate better. Been using it for years and I also live in a very cold winter area that it does its job!
Question:	How and where do you install the pressure gauge
Answer:	No, there are ridges, but not for measurement, only for secure grip. If you want to spray a dilution of some chemical/fertilizer/plant food/insecticide, you would have to measure it as per manufacturer's directions in another container that is marked for that purpose

In my experience there is always some pressure in the tank even when you have run out the product and no more air appears to be coming from the wand. Always slowly and carefully unscrew the cap and release all pressure before removing.
Question:	Can you use bleach in this Sprayer
Answer:	Yes you can use bleach as long as you rinse the sprayer very well after use.
Question:	Does the backpack straps come with this device
Answer:	Yes, they come with it and are adjustable, the 61900 has nicer thicker more cushiony straps. But both work just fine.
Question:	what's the PSI, just wondered all other sprayers in catalogs list the PSI in their comparrison sheets.....so there....spbbbbbbbb
Answer:	According to the manual with my #61800 you can select 30, 45, 60, or 80 psi. Selector is inside tank.

User questions & answers

Question:	How many HP
Answer:	It’s 3HP. I think it’s great for spraying insecticide, I use at a low nozzle setting and about 35%~50% throttle and it covers great. I wouldn’t recommend for leaf blowing. It doesn’t move much air when compared to regular Stihl, Echo, and other backpack blowers.
Question:	Does it arrive assembled? Does it leak much
Answer:	This Backpack Sprayer's reinforced plastic tank does not leak and comes assembled with the engine and backpack straps. The only assembly required is the throttle and tube configuration, which depends on your preferences/needs. A quick guide is available in the box or a more visual "How To" on YouTube.
Question:	Is this unit better than the italia unit that is sold here on Amazon
Answer:	I don't know the Italia but this one is very good. The motor starts right up every time and the sprayer works as it should. It has a great range. I sprayed around the house for mosquitoes and it's very effective. I also use it without liquid, just as a leaf blower.
Question:	who makes the engine
Answer:	This engine is engineered and manufactured by Tomahawk Power
