Why is my Solo 414 Backpack Sprayer not outputting any pressure?
If you Solo 414 isn’t quite working as it should, there are actually 3 x things that we need to check…
- Check for an airlock in the line & pump.
Air can get locked in between the tank and the trigger, but there is an easy fix for this. Simply turn the pump on and hold the trigger at a level lower than the tank, squeeze and hold.
What this will accomplish is the sprayer will force the air down and out of the wand. This will cause the pump to change noise once the pump is then primed and will become silent once your sprayer has built pressure back up and is ready to go.
- Check for filter blockages inside the tank.
If our first step hasn’t worked, the next thing we need to try is check our filter inside the tank for any blockages. Firstly, remove the lid of the sprayer and then the filter basket. Looking in the tank, you will notice a suction line coming from the bottom of the tank.
At the bottom of this suction line is a small, easily-accessible white strainer. Simply remove this strainer, check for blockages and give it a clean. While you are inside the tank, also ensure to check the top of the suction line and ensure that small clamp located there is tight.
- Ensure all clamps are tightened.
Thirdly, if our first steps have provided no solution, the next step is to ensure all clamps are tightened within the housing of the sprayer pump. Located on the sides of the sprayer are 4 x screws, holding the pump housing together with the sprayer’s tank. Let’s remove these screws and pull the pumps housing away from the tank, exposing the battery powered pump.
Upon doing this, you will notice a hose connecting the tank to the pump. Simply ensure that the clamps at either end of this hose and connected and tightened. This will ensure that no air will enter the pump, causing loss of functionality.
