We know how frustrating it can be when you are on a job and suddenly your Birchmeier Backpack sprayer doesn't seem to be building up any pressure. The valuable pressure that builds inside and then forces the spray out of the wand. Without it there ceases to be any spray coming out to treat the weeds or spray the pests. This is a big deal. Thankfully we have the knowledge and resources to help you out of this predicament.
Most often by inspecting the Check Valve and giving it a thorough cleaning or replacing it will fix the problem. Pulling off the air chamber will reveal the small white check valve that you can pry off with a screwdriver. Rinsing clean the valve to remove any debris buildup can help, we recommend replacing entirely once a year for heavy users.
Andrew Greess: Hi. This is Andrew Greess with QSpray.com. Here I'm talking about the Birchmeier Backpack. It's a terrific backpack. In our opinion, the best backpack built, but it does require maintenance. One of the things we see or one of the questions we hear from our customer is, "I'm having trouble building pressure in my backpack."
That could be a number of things, but one of the things that it could very well be is the check valve. If the check valve is worn out or if it has a little bit of debris in it, then the check valve will not be able to allow the backpack to build pressure. The check valve goes under the air chamber, right here. So, one screw to your air chamber.
Here's your check valve right here. You got to use a little screw driver and pry it out. It will not just come out. Just use a very little pressure on a screw driver and take your check valve out. If it's in a good shape, you can rinse it off, clean it out, put it back in.
What we recommend is probably a good idea, once a year, if you're have a user who relies on it for work, change it out once a year. You'll have a lot less struggle. Thanks for watching. Visit us at QSpray.com
