Having Trouble Building Pressure? Look at the Check Valve

Having Trouble Building Pressure? Look at the Check Valve

Posted by Andrew Greess on Aug 7, 2017

The Birchmeier Backpack Sprayer is likely a key component of your business. Maintaining parts so it works properly and lasts a long time is good business practice. There are a handful of key parts we recommend replacing/cleaning once a year to keep proper working condition on your sprayer. The Check Valve is one of those parts

The Check Valve allows you to build pressure in the sprayer, as soon as debris gets into the valve, you may find that pumping and building pressure is difficult. Simply pry it out with a screwdriver for leverage and replace. We also recommend having a back-up check valve in shop in case of emergencies, to prevent work stoppage in what could be a few minute fix.

Andrew Greess: Hi. This is Andrew with Quality Equipment and Spray, I'm talking about the Birchmeier backpack and some of the key components that you may need to do maintenance on.

One of the parts that you need to be paying attention to is the check valve. This is what allows the sprayer to build pressure. This is a sensitive unit. If it gets any kind of sand, debris, or dirt in it, you'll have a hard time pumping up your backpack.

The check valve is located underneath the pump cylinder. You'll unscrew the pump cylinder, and then the check valve is right there.

Usually, it takes a screwdriver to get it out of there. This one is brand new, so it comes out a little easier. Once you have some wear on it, you may have to use a little flat‑head screwdriver and pry it out of there.

This is a part you'll want to replace every year. You might want to think about keeping one on hand for emergency repairs because that is a part that, when it fails, it will take your backpack down, and you won't be able to use it effectively until it's replaced.
