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.

Question:	Can this sprayer handle Roundup Quick Pro
Answer:	Yes it will as long as the granulars are properly dissolved prior to spraying.
Question:	Can this sprayer spray log oil? Larry
Answer:	Not the application I purchased it for, but I think the pressurizing system isolated from the liquid, so should not damage sprayer.Nozzle orifice may need to be enlarged, which would be a trail and error situation. Worth a try. Good luck.

User questions & answers

Question:	How do you order a replacement part
Answer:	To confirm we are addressing the same cover, mine is the LETHMIK genuine leather Flat Cap Cabby Hat. It does have a stitched in lining in what appears to be a cotton/cotton flannel in a gray plaid pattern. The cap has two vent holes on each side. It appears to be of good quality material and construction. I have owned it about a year. I wear it only occasionally and in cooler weather. Therefore, I cannot comment how easily it is to soiling. Furthermore, I am balding, with minimal hair on the top and normal growth elsewhere. The washing instructions leave one with few options: 'Do not bleach. Do not iron. Do not dry clean'. Be aware that since the cap is constructed from several panels of leather, the shades of leather in the different panels will vary slightly, at least in the browns.
Question:	Is it manual pump or battery run pump to maintain pressure
Answer:	XL........
Question:	does this sprayer come with a harness
Answer:	There are 3 sizes available, Please choose the suitable size according to your head size, Thank you, and you can feel free to contact us if you would have any questions.
Question:	Will this sprayer work for spraying lithium densifier onto concrete floors? The product is relatively thin
Answer:	I really like this hat. I bought a size 8, but in actuality I can wear a 7-3/4. The reason I bought a larger size is because when it gets cool outside I use the in flaps that’s inside the hat to cover my ears. So if you don’t want to cover your ears just leave the flap tucked inside!

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

Product description

The 4 Gallon Professional Backpack Sprayer is capable of producing up to 60 psi, with a high-performance connecting rod-actuated diaphragm pump system. The diaphragm is made of top quality material for its resistance to harsh chemicals, including bleach and for its long life expectancy. For spraying large jobs or small it is capable of performing virtually every spray ring task and will easily and effectively handle disinfectants, fungicides, herbicides, insecticides and fertilizers. The 475-B is designed with the ability to pass small abrasive particles without damage to the pump system and may be used with water from wells, lakes or rivers, which may contain sediment. The diaphragm backpack is ideal for handling chemicals in wettable powder form, liquid formulations and bleach solutions.



Note:It takes initially at least 20 – 22 pumps of the handle to fully pressurize the sprayer.  Once pressurized, the user can spray for approximately 1 minute before the pressure starts to drop.  Pumping the handle 4 – 5 times will bring the sprayer back to full pressure.  As the pump handle attaches to threaded pump shaft with two cap screws, there is no need for locking nuts to secure the pump handle. 

The Solo manual 4-gallon 90 psi high-pressure backpack sprayer features an ultraviolet resistant tank, felt padded polyester straps, a heavy duty pressure cylinder and reversible pump lever. The high pressure backpack sprayer is made of all high-grade, corrosion resistant plastic, with no metal or rubber parts made vulnerable to chemicals. The chemical backpack applicator includes a connecting rod actuated diaphragm pump made of high-quality Viton that resists harsh chemicals and produces a wide pressure range up to 90 psi. In addiction, it features a 4-foot high pressure hose, a spray tube of 55 cm, and can carry up to 12 pounds. With its easy operating shut off valve, 4-1/4-inch opening with filter basket, and 28-inch wand overall length for hard to reach areas, it can handle disinfectants, fertilizers, herbicides, and pest control products for efficient tree, shrub, and plant protection. This tool is backed by a 1-year limited manufacturer's warranty.

• Easily and effectively handles disinfectants, bleach solutions, fertilizers, herbicides, pesticides and formulations for tree, shrub and plant protection.
• High-performance diaphragm pump for use with wettable powders, liquid and bleach solutions. Passes small abrasive particles without damage to the pump assembly. Produces pressure of up to 60 psi.

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:	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:	just bought one of these sprayers. The pump never shuts off even when not spraying. Is this right or is this unit defective
Answer:	use the nozzle trigger to turn it off. the full time pump running allows the spray to me more consistent , and if say spraying weed killer having the spray go weak and then hitting things not to kill would painful. please use the nozzle valve. that is how it works , same as pump up hand sprayer that has pressure tank, consistency is important. your pressure washer does this too. engine keeps running, for same reason, as does water hose to house bib. demand pumps are not good here ,like seen on RV water faucet , not at all good and are one more thing to break and cost more. simple is best. and no drooping decaying spray wanted ever.
Question:	What’s the psi
Answer:	It doesn't say the psi but it sprays 400-480 kg of fluid on a single charge. its not a power washer but sprays weed killer and bug killer awesome. I have 1/2 acre and I sprayed it in no time. i had to fill the tank like 4 times because it sprays fast. but it also comes with different spray nozzles to control how much your spraying.
Question:	Am i missing something here? sprayer turns on when plugged in. and green light glows on cord box when plugged. won’t work when unplugged
Answer:	Must leave it plugged in for several hours in order to charge😊
Question:	Why did this sprayer not include the most commonly usesed nozzle. A straight stream that is adjustable
Answer:	There a lot of nozzle adjustment to use this machine... by the way if you have an older nozzle it my fit on this... try it

User questions & answers

Question:	CAN i buy a hose and sprayer handle
Answer:	You will need to remove the wheels in order to replace the caps.
Question:	Can I use bleach in it
Answer:	I think they will I have not installed mine but they should work just fine
Question:	Does this come with an adjustable spray tip
Answer:	It didn't fit the 1985 EZ-Go that I was working on. The cap was correct, but the Float Slides that the Foam Gauge slides on were too long by about 4 inches. I was able to cut them shorter and reweld them in order to make it fit and operate correctly. Amazon nor their Supplier listed a Gauge Length. The Gauge Length is the portion that actually fit down into the fuel. So other than the modifications that I had to do, it ended up working in the 1985 model
Question:	I’m trying to find a new piston where my nozzle attaches cracked off
Answer:	Yes they are vented. The gas caps have a small hole in the gauge face, that allows full venting. Should work fine, as long as your tank is at least 12 1/2" deep. Thanks The Part Connection
