The Jenny Box and Pump
A Jenny Box is designed to act as a type of filter. Every reasonably clean pond or pool needs one. It also provides some protection for your pump against large debris.
I am going to show you how to clean and reassemble a solar pump and Jenny Box. I will explain how this Jenny Box was constructed at the same time.
Step 1: To clean, take the Jenny Box out of the dirty pool.
Step 2: Take everything out of the box. All that should be left is the the over-sized plastic shoe box you started with and the attached filter.
Step 3: Be sure to clean the dirt out of the holes you drilled on one side. You can do this effectively with a hose. (These are small holes drilled all over one side at random.)
Step 4: While the box is out of the water, examine the zip ties you used to attach a piece of filter material over the holes in the side.
Step 5: Once you have washed the filter out with a hose, place it back inside of the Jenny Box.
Step 6: Take a hose to the pump (the pump should be turned off), and clean the pump.
Step 7: Replace the filter material to completely cover the solar pump, leaving the extension piece sticking out.
Step 8: Be sure to keep track of the cord. It should be coming out of the edge of the filter that is wrapped around the pump.
Step 9: Replace the aluminum screening material you place over the entire box. This material hoses off nicely and comes reasonably clean.
Step 10: Be sure to push the extension piece and cord through the holes on the screening. (In the future it will already be there; no need to remove completely to clean.)
Step 11: Replace the outside piece of filter material which also leaves a hole for the cord, and the extension piece.
Step 12: Replace the lid in which you have cut out six--two inch circles. (Be sure to feed the cord and the extension piece through this lid also.)
Step 13: Replace any fountain head that came with your pump.
Step 14: Make adjustments to the fountain head to achieve the flow you desire.
Step 15: Place the Jenny Box back into the pool.
Step 16: Place a rock or two on top, being careful not to cover too many holes in the top. This weight helps to keep the Jenny Box submerged.
