SOLO 456-HD 2-Gallon Heavy-Duty Tank Sprayer with Viton® Seals Throughout to Withstand Harsh Chemicals – Designed for Waterproofing, Pest Control, Sanitation, and Surface Treatment

I have purchased many new solo sprayers over the years and all (excluding the last one) of them have worked fantastic. Mainly used for natural farming foliar sprays. The last one I purchased was used "like new" but showed up defective (air leak in pressre tank). Highly recomend always buying new with these as waiting a week for a defective product you may need for a specific scheduled foliar spraying is a hassle. Still the best brand sprayer I have used to date. Besides amazons defective used product this is a 5 star product.

Out of the box it did not work. Unfortunatly I was not concerned, since it was a sprayer, that it would work. My project (seal fence} got delayed and when I took it out of the box it did not work.... Missed my return date by three days....After I wrote this review I attempted to contact SOLO support. Was not able to reach them as the support voice mail box was full....turns out this is a $70 lesson. Should have read the reviews.I tried again on May 15 to reach their tech support and got the same message, "mail box full". Sent them an email on May 12 and have yet to receive a response.

Purchased this sprayer because I had always had good luck with the Solo brand. Right out of the box it would not work; would not hold pressure when pumped. Easy return with Amazon and a request to replace it with the same sprayer. Same thing.....would not pump up or hold pressure. 2 strikes and I was out. Amazon took it back with no questions and I purchased a Smith and it works great....better quality than the Solo.

I bought this sprayer based on the recommendation of the deck stain manufacturer. It simply did not work. I followed instructions, tested and greased seals. It did not hold compression, and leaked. Past the return window, this one went to the landfill sadly.

Leaked air from the top cap right out of the box. Easy return, but at this price point I'd hope they could make a top gasket that would seal reliably.

First Time use: Initially just fine. then bottom ballooned out after pumping up, Now cannot sit down on a flat surface. Very disappointed.
