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.
Question:	Has anyone had any experience with using this sprayer for a stain or oil based product for spraying/staining a split rail fence
Answer:	use a $20.00 plastic cheaPO 1 gallon pump spray worth it for large deck saves serious time ive done this 5 plus times solvents and stayin etc usually ruin pump in hours make sure finish same day b/c next day pump might be junk
Question:	How many gallons does it hold
Answer:	The tank holds 4 gallons when full; it has graduated markings of 1, 2, and 3 gallons also. When full, it weighs 50 pounds. The back pack makes it feel like less than that once you have it on your back. This is most easily done if you set it on a bench top or table top, and then "slip" into the harness.

User questions & answers

Question:	How do you release the pressure between uses without wasting product? Is there a valve I'm overlooking
Answer:	The only way I know of is to slowly and carefully unscrew to tank cap until you hear the air flow. 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:	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:	Does Petra offer shield sprayer attachment like an oval drift guard ? Want to use this baby in my commercial organic garlic field for weed control
Answer:	We do not currently offer a shield sprayer attachment.
Question:	Can it be used with hot water and carpet solution
Answer:	Yes, you can use the backpack sprayer with a carpet solution but please make sure that the water is not too hot.
Question:	Does this sprayer have a Prop 65 warning for CA customers
Answer:	no
Question:	How far will the sprayer spray a stream. I want to use to spray second story windows and gutters before pressure washing
Answer:	I do roof and exterior cleaning....just what are you spraying on gutters and windows that you can't do without this backpack sprayer? I use SoftWash Systems Green Wash in my mix. It has a bleach catalyst so it reduces the amount of bleach required and saves money. Maybe not a huge deal on a house wash, but it makes a big difference in roof washing by reducing bleach and reducing salt content. Green Wash also has a rinse aid so when you come back and do a rinse after a house wash the window come clean and rinse easily. In 8 years I've never had a customer complain about their windows after our service. Gutters? I'm assuming you're using something like Gutter Butter, Gutter Zap, Purple Power or similar product for gutter brightening? If this is the case, I'd recommend a Flowzone backpack sprayer that has 1/4 inch quick connects so you can use the default spray wand for single story gutters, and with the QC fittings you can use pressure washing extensions to more easily reach higher surfaces. This appears to be a good sprayer, especially at the price point, but QC fittings make using a sprayer like this much easier, especially since pressure washing fittings and such are already QC ready.

User questions & answers

Question:	does this version also come with the 25psi regulator
Answer:	It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi. It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure.
Question:	does this have a built it agitator and can wettable powders be used in it
Answer:	No agitation. It’s a manual backpack.
Question:	So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions

User questions & answers

Question:	How high can this spray? i need to spray wet & forget on two story siding with a high gable. thanks
Answer:	Enrique, did you purchase the pump spray? I also am considering W&F on my 2 story gabled house. LMK how it worked out for you.
Question:	Is this a "motorized" sprayer or do you need to pump it
Answer:	You need to pump. There is a lever on the side that you push up and down as you spray. You basically build up pressure in the tank and you pump to maintain that pressure.
Question:	Is this a piston or diaphragm type
Answer:	Hi Frankie. This backpack has a piston pump. If you have any further questions, please call our Customer Service Team at 1-800-950-4458. Thank you for your question, we appreciate it.
Question:	Does the wand leak
Answer:	I've had mine for about 4 years and I use it quite a bit since I have a lot of weeds in the area. I've never had a problem with the wand leaking, so I suspect Caryn probably didn't tighten it properly... I see the other commenters did not have a leak problem either

User questions & answers

Question:	How long is the hose that come with unit
Answer:	Yes but make sure you use the acid/bleach wand with the plastic valve handle. You can use the stainless adjustable wand and spray pistol (if purchased) for all other fluids including pest, lawncare, solvents, etc. Thanks Lance@MY4SONS
Question:	No one mentions how far it sprays. I want to use it for spiders and need to reach second floor windows. How far will it squirt
Answer:	Battery life can range from 1-3 years or more depending on use conditions and adherence to best charging practices (plug in after each use). The charger is fully automatic so you can leave it plugged in all the time. Battery replacement cost is $18-$29. Lance@MY4SONS
Question:	Will The sprayer work if I put in a tilting 2 wheeled cart and pull it around
Answer:	If you clean it afterwards really well. Not recommended
Question:	Does this sprayer circulate the contents? I want to use an oil in water emulsion, however, the oil phase tends to float to the top
Answer:	Ed...I just got an answer from Lance about battery teplacement. Here ia a copy: Hi Dave,Not at this time. We are currently reviewing potential battery suppliers based on quality, lead time, and cost and are hoping to have batteries available to customers within 1-2 months. In the mean time, there are several stores on Amazon offering 12v 8ah AGM sealed lead acid batteries at good prices. We prefer lead acid batteries to NiMH and Lithium Ion because these pumps don't require high surge current and lead acid is a proven technology and reasonably priced.Thanks,Lance

User questions & answers

Question:	After only 3 uses the unit began to leak from the cylinder on the bottom. Is there an adjustment that can be made
Answer:	try tightening it but if not return it or ask the manufacturer about it. Just remember to clean the tank and sprayer out after each use as whatever chemicals you're using could corrode the unit. Hope this helps
Question:	What does that lever on the left attached to the bottom of the tank do? I'm looking for something that I don't have to pump before I spray
Answer:	The pump handle is for pressuring the unit so you can spray out the liquid. If you are looking for a unit that does not need to be manually pumped we would suggest the lithium-ion powered backpack sprayer. If you have any further questions please contact Customer Service by calling 800-311-9903 or by emailing [email protected].
Question:	Yes, the sprayer is not holding pressure after my 3rd use, what do i need to do
Answer:	I have not had this problem. Check the lid to make sure it is on tight.

User questions & answers

Question:	I see a side shoulder strap, does it have a harness back strap
Answer:	Adjust the nozzle or put different nozzle on. Atomizing is preferred for some tree or shrub spraying, but you need to adjust the nozzle. Good pressure is great.
Question:	Can i use bleach in this sprayer
Answer:	I have the same issue. I believe it's because the internal pick up tube is too high i also need to see if i can have my harness replaced either way still lasts me about 2 house treatments maybe 3 depending on square footage. I'm actually looking to order a second one as mine is finally a year old. Still works after the abuse of arizona residential services.
Question:	where can I find replacement parts
Answer:	I know it will not with a Porter Cable 20v. The 18v it comes with lasts a long time.
Question:	What is the weight of the unit fully filled
Answer:	Si, trae cargador para la bateria. Gracias

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.
