Previous experience with sprayers of this type is that either the nozzle or spraying tip clog after minimum usage. Why would your sprayer be any different?
The quick answer to your question is that our sprayer is no different. But that would be an incomplete answer. Let me explain.
I have been using all kinds of sprayers for over 30 years. Many of these were pump sprayers but some were hose end (hook up to garden hoses), others gas powered and still others electric. The one thing they all have in common is that their tips (nozzles) can get clogged. In virtually all cases I was to blame. Let me explain.
Initially I had a bad habit of setting the pump unit of the sprayer down on the ground where it could pick up all kinds of dirt and debris. Suffice to say this led to problems. But it was easy to figure out and I quickly learned to protect the pump so it never touched anything dirty and if it did, I was sure to wash it off prior to placing it back into the holding tank of the sprayer.
I then found out the hard way that if I didn’t use all the chemical tank mix I made but instead stored it for just 1-2 days, there was likely to be some kind of crystallization or clumping inside the tank that would lead to clogged tips. The resolution to this problem was to make sure I never left anything in the tank when I was done spraying. Easy enough I thought…
Well, not so fast. Leaving just a little product in the bottom of the tank can be bad. Remember, all that’s needed to clog a tip is just a tiny bit. The 1/2-1 oz at the bottom of most any tank even after it’s poured “dry” is all it takes. So I then learned to rinse out the tank 2-3 times at the end of each work day making sure nothing but water was left on the bottom.
Guess what. It turns out you also have to drain the hose from the valve to the tank even after you empty the tank because failure to do this will allow the spray solution in the hose to coagulate and clog the tip! Again, I found this out the hard way…
At this point I figured I had it under control but still my spray tip would clog! In the late 80’s wettable powders began to be commonly used and I loved them. Though this formulation did great in the field and had many benefits, it definitely led to clogged tips. Again, my decision to use them and therefore indirectly my fault for the sprayer nozzle clogs. But once I learned about this “inherent” problem, I made a point of cleaning the nozzle after each use if I was mixing a wettable powder that day. Still I had problems…
Turns out “over the counter” and “ready-to-use” sprays can contain all kinds of contaminates and ingredients that can be a real problem for some sprayers. They also tend to “react” funny to anything other than their own formulation. Adding a little water left over in the tank can be a problem. Fortunately this was an easy fix; I was in the pest control industry and used mostly concentrates that needed water and nothing else to create a spray mix so I simply avoided the ready to use solutions.
Lastly, I found out the hard way that spraying herbicides, mold killers, fungicides and pretty much anything other than the refined pesticide products designed for use inside homes would all lead to my sprayer getting clogged quickly. Apparently these “other” products don’t have to make their solutions nearly as refined and in the end, the spray solution made with them will definitely clog most any sprayer a lot faster than a good insecticide. To prevent them from bothering my good sprayer, I started using separate sprayers for all the different types of products I wanted to spray.
I now keep one good sprayer for just “clean” pesticides. These would be products I use in or on the home. I also keep a separate sprayer for lawn products, another one for “total kill” lawn products and a fourth one for cleaners like bleach and detergents. At this point I know I keep the pesticide sprayer the cleanest but it’s for the home and therefore is spraying the most refined products. For this reason it’s imperative I keep it clean. The herbicide sprayers can get a little clogged and it’s hard to notice. The “detergent” sprayers tend to keep clean as long as I rinse them out good after use. But if I leave anything in them for more than a few days, many times the sprayer gets so muffed up it’s not worth saving due to all the internal meltdowns that can distort the inner gaskets and seals.
So to answer your question again; no, our PORTA PAK SPRAYER is no different from any other sprayer. It’s most definitely subject to nozzle and tip clogs just like all the others on the market. But if you take some advise from someone that’s spent a lot of time both spraying and cleaning sprayers, this “nozzle clogging” issue is most definitely something you can avoid using some of the tactics and setups I described above.
