Ortho Dial N Spray Hose-End Sprayer for Liquid Weed and Insect Killer, Fungicide, Fertilizer with 14 Dilution Settings...

This sprayer really exceeded my expectations. I bought it because my tap water is very alkaline at pH 8.0, but I've wanted a pH of ideally 6.0-6.7 or so for my outdoor container garden plants. The hose end sprayer delivers the pH Down I added with a consistent pH. I can recover the product to change the solution in the sprayer, which is a very nice feature. The different spray settings click into place nicely. The flow rate is very strong, much stronger and faster than my Miracle-Gro sprayer. I noticed a prominent review for this product suggested defeating the built-in filter mechanism to increase the pressure, saying that filter or governor "doesn't need to be there." False! That's a backflow prevention mechanism, from what I can see! So that should be left in place. From the pressure of my standard household water tap, this sprayer was very powerful and needed no adjustment at all. It filled a quart size container in seconds. All I had to do for this sprayer to work perfectly was connect it... I love it. No issues yet. Here's what I did with my Ortho Dial N Spray to adjust the pH of my container plants: I bought pH Down (Bloom City Professional pH Down Liquid Fertilizer) and followed the instructions on the bottle, adding 1 oz of the pH Down stock to the hose end sprayer container and filling it to the 32 oz line. I then set the dial on the Ortho Dial N Spray to 1 oz and tested the pH using pH paper (Micro Essential Lab 2210 Plastic Hydrion Vivid Short Range pH Test Paper Dispenser, 4.5 - 8.5 pH, Single Roll) and an electronic probe (YINMIK Digital pH Tester for Soil), which gave similar results within 0.2-0.3, indicating a pH of 6.7 +- 0.3. So, it had already brought the pH down into my target range! To acidify the water further, I simply moved the hose end sprayer dial from 1.0 oz setting to 1.5 oz, measured the pH of a quart of the emitted water, and sure enough it had moved further down to 6.4, and there I've kept the dial. I dumped the quart of water, filled another quart, tested the pH, and it has held steady. This leaves no doubts to me that the Ortho Dial N Spray will meter out other concentrates in a steady manner as well. However, I only use pH Down for container plants and do so lightly, because it supposedly contains phosphate, which can pollute waterways. Please use whatever you put in your sprayers in a responsible and environmentally friendly manner!

I bought this to broadcast apply insect killer on my yard and trees that get ravaged each year. The three settings are nice for type of spray and it does reach the top of my trees (15 feet). At first it was leaking quite a bit but I added a second washer and not a drop leaks now. The ability to empty unused product back into the bottle is really nice. As for the application rate I cannot really comment but for my use it seems fine. Bugs are gone and I got good coverage with much less effort than a pump sprayer.

This hose end sprayer is light weight and simple to use. Just follow the instructions and you will quickly get your yard efficiently sprayed. Easy to clean, just flush by simply increasing the the adjustment on the dial and let the clean water flow through for 30 seconds. I am happy with my new sprayer and would recommend.

This works super well, very easy to customize to your needs. Only advice is to not spray anything besides liquid. Even if you have very small particles in your mix it will clog, even if you remove the filter screen it will still clog further up the line. Otherwise it's amazing.
