GARDEN SPRAYER PRESSURE MODIFICATION
It is a constant annoyance to have to keep pumping a garden sprayer . There is an answer. As long as your sprayer has a pressure relief valve, you can pressurize it with a compressed air source and spray away for quite a while longer than you would from hand pumping.
Here's what you need:
Tubeless tire valve stems, and an installation tool.
A drill with a 1/2 inch spade bit.
Here is a common 1 gallon sprayer, ready for modification.
Drill a 1/2" hole in the tank.
Wrap a piece of duct tape around the valve stem.
Feed the duct tape throught the hole.
Holding the valve stem with the pliers, remove the duct tape and attach the valve stem installer.
This is how your newly modified tank will look. You can now use a compressed air source to "charge" your sprayer. The pressure relief valve will allow air to escape when the maximum allowable pressure is reached. Common safety procedures would warrant not leaning your head over the sprayer while charging. Also be sure that the hose is securely fastened at both ends.
