Good product gone to rubbish
OK, so I have owned and regularly used - weekly - a Solo 425D backpack sprayer for many years, all without trouble. About six months back I decided to purchase a second sprayer for the use of Herbicides and Insecticides only i.e. no Glyphosate. After only a few uses this sprayer stopped working. I couldn't get pump pressure and as such I thought OK the diaphragm has gone (no idea really). Well, that's not good but I will buy a repair kit. Not so easy, it turns out there are several repair kits available all of them expensive and relative to ...a particular problem. So (some months later) I thought, I'll keep that for spare parts and buy another so I did. On the first use of the new unit, after filling, I noticed that the cap wouldn't screw on properly. I tried the cap from my other sprayer and same result. So, I used it emptying much of the contents down my back. I then contacted the hardware store where I made the purchase and ordered a replacement. A few days later I collected the replacement and returned the original, I checked the lid and all good. So, again I filled the sprayer with chemical, slung it over my back and went to spray - not working. The handle just flopped up and down and I could hear some rattling inside the pumping area. Not happy at all. I rang the hardware store - the one in the big green shed - they apologised, though not their fault, however could not replace the Solo immediately as it was a 'Special Order' item, which I already knew. I was less than thrilled as I had added approx. $80 worth of chemicals to the unit which had to be used within a few hours or it would deteriorate. They - the people in the big green shed - agreed to replace my Solo with another brand (Sylvan) which was actually $40 dearer for no additional cost, a wonderful gesture considering none of this was their fault. I accepted their offer. I am happy to say the new sprayer is excellent. As for Solo? Though my old original sprayer works fine - touch wood. Well they have lost me forever. Three duds in a row tells me all is not well with their manufacturing and quality control processes'.
Excellent - has changed my attitude to spraying
Comfortable backpack - well balance and easy to pump. The spray head is great and covers a big swathe. I can now weed spray our 250 metre long gravel driveway with ease. Very simple straightforward design - easy to fill - simple filter, stands up by itself when filling tank. Can't fault it for the price.
Cheap. Had no problems with it.
I don't get it. I have read other reviews and I see people complaining about it being expensive. It cost me $50- from Roberts, who aren't exactly a discount retailer. It doesn't seem expensive to me? Anyhow I haven't had any serious issues with it and I certainly can't claim to have treated it well. Only rinsed out the system a couple of times, when I was changing poisons.
The spray wand is a bit awkward, sometimes jamming on and lately the on lever is not springing back automatically. Bit annoying. But like I say, it was not expensive so w...hat would you expect, for a plastic spray wand. As other people have noted, the shoulder straps come detach too readily, but perhaps that could be a plus in an emergency, so its no big deal. At least they don't detach once they are on your shoulder with the weight of the backpack holding them in place. Overall, not bad at all, for the money.
Base of tank join.
Have a carpet cleaning business and have used these sprayers for a couple of years. just recently have had 3 split on the bottom along the join, the last one lasted two weeks before coming apart. now they won't replace under warranty. It's only a mild detergent for pre spraying.
Good unit works as intended. I am happy but.......
I have used my 475 on a farm with a range of chemicals. If Solo spends another $1-00 during manufacturing, I would have given it an excellent rating.
As someone else mentioned, I have also had the plastic hose clamp work loose causing the hose to come off. If this was a metal clamp I doubt it would happen, but if a metal one was used and over tightened it could cause the tank fitting to fail.
The second issue is the hose needs to be about 30cm longer.
I would buy another one tomorrow and modify it with my lessons learnt.

Solo 425 model with the DOP purchase 27/04/2017.
The pump is good.
The air valve in the lid works well.
The carry handle is an improvement.
Hose is awkward.
Pump handle flops to inappropriate positions.
On falling forward the pump handle at 110 angle may impact the chest to the user. ...
I like the concept of having a backpack but I don't like the plastic type of spray nozzles... I will try to buy a brass one. I don't like the clip on the bottom of the strap that clips onto the bar. This often comes off. Why isn't it fixed and user can adjust the length. I like the 15 litre capacity.
I would not buy another one.
1. The wand is short and not adjustable so if you are tall it will make your back ache.
2. The handpiece failed after about 6 months.
3. After about 2 years of casual use the pump failed so I went to order the parts to repair it and thought I would also order a longer wand. Turns out he parts are very expensive and I was better off buying a different brand unit which is much more comfortable. So the Solo is in the landfill.....
A great tool - could only be replaced by another Solo!
My old Solo sprayer died this morning when the frame broke up underneath the tank. I am a viticulturist and I checked the purchase date: It was in 1981! Sounds fair: 34 years. This is one of two Solo knapsack sprayers I have been using, along with a Solo airblast sprayer, which is 15 years old and starts first pull - still!
Only had the thing 8 years!
I can't believe all the negativity. I work with mine day in and day out. My best purchase ever, never lets me down. Like all bits of kit, it needs parts replacing. That is a given! I love my knapsack sprayer, wish my mowers would last as long. I'm a professional gardener. Have been doing this for 15 years. I know what I'm talking about!
waste of money
Within the first 2 weeks the unit failed to pump and hold pressure. The metal (spring looking) o ring in the piston assembly failed and after going to the online instruction manual I have to purchase another one. In addition the Viton collar on the piston is warped. When I tried to disassemble according to instructions another o ring needs replacing and I was unable to remove the pump assembly as advised. The manual also advises to grease the piston. The piston was bone dry after approx. 2 hours of operation from new so it obviously had none on it from the factory.
Better off buying cheap one till it wears out and keep doing that....
I have worked in natural resource management for many years and have used various knapsacks including Birchmeier, Chapin, Kinchrome etc. In my opinion, Solo 475 is by far the most reliable and comfortable knapsack sprayer. We have multiple units at our workplace and they continue to perform well after 100's of hours use, with very little maintenance other than cleaning the filter in tip. Have replaced a broken handle, that's about it. Cheap knapsacks aren't worthwhile, you'll end up covered in herbicide and the unit will be in the bin before too long. I haven't used the Solo domestic units (425D), so can't comment on their quality.
Not very good
I have no experience with backpack sprayers, so I purchased one that I thought would be pretty decent - especially given the high price. I think this was a mistake and the product is overpriced for it's build quality and features.
DIFFICULT TO STORE AND HANDLE DOESN'T FOLD AWAY
My first disappointment was that once assembled it is much larger than the size of the packaging would suggest, due to the handle that sticks out straight and cannot be folded upwards or anything. You would have to disassemble it for storage. Where am ...
I haven't used it much as first of all I found it hard to fit in the car as the handle only sat horizontally, not vertically. I then got on-site storage, and the second time I used it, I felt it dripping down the back of my legs before I put any pressure in it. So I went back to my old $30 backpack spray which I had had for 4 or 5 years.
Expensive, leaked on second use, handle position.
good quality commercial backpack 475
used the backpack a couple of times a week for the past 2 1/2 years, as an gardening contractor, and have had no trouble, previously had much cheaper hills backpack sprayer, that only lasted a year,
mine was the diaphragm solo 475 model, which i was recommended by the dealer !! I was given an old battered piston model by a gardening contractor friend, and found that to be reliable too,
very reliable, quite comfortable, alters for left or right hand
mine was quite expensive,
Very poorly made
I wanted a good back pack sprayer so I thought I would go with the best and get the German made Solo knapsack sprayer.
They have two models which is the commercial one and the domestic one, so I have bought the commercial one, and it has been a big disappointment at best, for one I don't believe it is made in Germany, they have got German engineered but no mention of where it is made, and going by the build quality I would suggest it is being made with cheap labor, which is OK but the price should represent that as well.
My first problem was ...
Questions & Answers
Anyone else had trouble with wand leaking between spray zones? Distributor told me they are known for this and I would have to buy another part to try and fix this.
Sorry I haven't had any problems at all with the pack or the wand. We've been using it regularly for over 2 years and haven't even had to clear the spray head. Why don't you contact Solo directly? They have a reputation to protect and might help you out. Good luck.
I'm not sure what you mean by leaking between 'spray zones' if you mean you take pressure off the trigger mechanism and it continues to spray (albeit lightly). Instead of just releasing the trigger by reducing pressure on it softly, let it flick back to the off position by force from the spring. My (only functioning Solo) partly shuts off sometimes and this fixes the problem. After doing this a few times it normally self corrects. If you mean the different 'zones' of the wand and the joiners leaking they only use 'o' rings and it's easily rectified with a new one which are available in numerous locations. Good luck contacting 'Solo' their product has gone to rubbish.
what is the difference between the 425D and the 425LC?
