How To Refill Roundup Hose Sprayer

The Roundup Pump N Go Sprayer is one of the most popular weed sprayers on the market.

Thanks to its efficient design, it allows you to spray continuously without experiencing any hand fatigue. Additionally, you can refill it quickly once the formula runs out, but it’s crucial to know the essential steps. 

I’ve compiled this excellent guide to help you learn the best way of refilling the Roundup Hose Sprayer. So, let’s get started.

Different Types Of Spraying Formulae

The Roundup Pump N Go Sprayer comes in a 1.33-gallon container, and you can either use a ready-to-use solution or a tough brush formula. 

1. Refilling A Ready-To-Use Formula 

A. Depressurizing The Sprayer 

First, you need to depressurize the sprayer by pushing down on the handle and turning it counterclockwise, which will release the pressure. Perform this step outdoors or in a well-ventilated area, and make sure to wear safety goggles and gloves during the process. 

B. Removing The Cap 

The next step involves removing the cap from the pump and, subsequently, the pump from the handle. For this, you need to turn the sprayer handle counterclockwise, which will unscrew it and allow you to remove the pump. But do not keep the handle on the bare ground but on a newspaper for safety purposes. 

C. Refilling The Pump 

One refill pouch of the Roundup Ready-to-use Weed and Grass Killer is enough to fill the sprayer pump. Pour the formula into the pump slowly, which will prevent foaming, and make sure not to overfill it. Also, the mixture does not require any water since it is premixed. 

D. Replacing The Cap 

Finally, replace the cap and screw it tightly by turning it clockwise until it locks securely. 

2. Using A Concentrate Mix 

A. Depressurizing The Sprayer 

The first step will be the same in this case also. You will need to depressurize the sprayer by pushing down on the handle and turning it counterclockwise. 

B. Removing The Cap 

Turn the handle counterclockwise and pull it away from the tank to remove the cap. Again, take care that the handle does not come into contact with the ground. 

C. Refilling The Sprayer 

Measure about 16 tablespoons of the Roundup Concentrate Poison Ivy Plus Tough Brush Killer and pour it into the pump. Then, slowly add water, but don’t fill to the brim so that the pump can easily be reattached to the sprayer. 

D. Replacing The Cap 

In the last step, replace the cap and turn it clockwise to lock it tightly.
