Indoor Plant Watering Device Using Repurposed Agriculture Bug Sprayer

If you have a plant obsession like my wife and I, than using watering jugs quickly becomes a real problem. It takes FOREVER to keep the babies watered. By the time you are done, your back and legs hurt from lugging jugs of water around the house, and going back and forth to the kitchen to re-fill the watering can.

We tried upgrading to larger 2 gallon bug sprayers, but constantly have to pump them up, and they are still HEAVY to pick up and lug around.

I set out to solve the problem for us once and for all! Turns out the perfect device already existing, I just need to re-purpose it a bit, and fancy it up.

Our new watering device holds 16 liters of water, it has wheels so you don't have to pick it up EVER, and there is no need to constantly pump it up, as its it is electric and stays changed up.

With our new device we can get all the plants watered in about a half hour, whereas before it would take us hours, and crush our backs and legs.

Supplies

• 1 slotted head screwdriver
• 1 phillis head screwdriver
• 2 cans of spray paint using your desired colors
• 50f silicon tubing
• 16L Electric Agricultural Sprayer
  • Agriculture Plastic Knapsack Electric Farm Water Sprayer Power Spraying Tool Power Tools from Tools, Industrial & Scientific on banggood.com - https://banggood.app.link/I1fI8qAwr2

Step 1: Disassembly

Its quite easy to take apart really.

• Remove all parts that can be removed by hand, this leaves you wit the tank/pump assembly
• Separate electric pump assembly from the tank
  • Pop the plastic rivets holding the soft backpack pad, I used the slot headed screwdriver for this. Save it for later. I cut it down in size to still use it as a pad between the tank and wheeled carrier, but its not really required.
  • Remove the 6 phillips head screws holding the pump assembly to the tank, take care to not separate them two far
  • Once separated, you will need to loosen the hose clamp holding the two assemblies together
  • Inside the electric pump assembly, you will want to loosen/remove one of the screws on the pump so you can pull it up a bit.
  • Remove the second hose clamp to the main assembly. I don't like the hard poly black hose, and needed to replace it with 50ft of silicon tubing. This allows me to walk around and water the plants without having to pickup or roll the device around the room. The only time I ever move it is to fill it back up with water every few weeks
• NOTE! You may find that the pressure of the pump is too strong for your needs. In that case when you have things disassembled you have an opportunity to adjust the pressure of the diaphragm pump. I've included a photo of a typical assembly. Its a screw dead center on the end of the pump.
  
  

Step 2: Painting

My wife would NEVER let me leave something this ugly in the house, so I had to pretty it up a bit.

• Clean all the parts with rubbing alcohol to ensure their are no oils to interfere with the painting
• Mask everything you don't want painted, I mask all the electronics components, and switches, dials etc
• Hang up the pieces in the garage and paint all the black parts your trim color (blue in my to match our decor)
• Paint the tank, and metal handle part your main color (white in my case)
• the little bits and fittings I painted on a piece of cardboard

I could have spent more time on pre but I was just trying to make it not ugly, I wasn't going for perfect!

Step 3: Re-Assembly

After things are all dry at least 24 hours

• Remove all masking tape
• Attach 50ft silicone tubing with hose clamp
• Re-secure the pump (remember we removed one screw)
• Set the pump assembly and the tank next to one another
• Re-attach the hose clamp that connects the pump to the tank
• Lay down flat and re-attach the 6 phillips head screws to secure the pump assembly to the tank
• Put the tank/pump assembly back on the wheeled carrier and secure with thumb bolts
• Re-assemble the handle seembly
• Re-assemble the sprayer assembly
• Fill with water and enjoy!
