No Pressure? Birchmeier Check Valve

No Pressure? Birchmeier Check Valve

Posted by Andrew Greess on Oct 18, 2016

We know how frustrating it can be when you are on a job and suddenly your Birchmeier Backpack sprayer does not 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 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 the valve clean to remove any debris buildup can help, we recommend replacing entirely once a year for heavy users. The next time you’re wondering why your backpack sprayer is not building pressure, make sure to check and clean your valve.

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 customers 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 sprayer 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 screwdriver and pry it out. It will not just come out. Just use a very little pressure on a screwdriver and take your check valve out. If it's in a good shape, you can rinse it off, clean it out, and put it back in.

What we recommend is probably a good idea, once a year, if you have a user who relies on it for work, change it out once a year. You'll have a lot less struggle — no more wondering why your backpack sprayer is not building pressure. Thanks for watching. Visit us at QSpray.com.
