This device will automatically add water to your pool when it gets below a specified level. It does this all for under $15. By having a device fill the pool to a specific level, you can avoid wasting water by overfilling.
Step 1: UPDATE: VERSION 2.1 Cross Section Added For Stability
After version 1.0 kept falling over in the water, I added a cross section for stability. I spray painted the PVC Black to help protect it from the sun. It also makes it look much more finished.
Step 2: Materials
You Will need
(1) Toilet Tank Fill Valve
(1) 3/4" PVC Pipe (At least 2 feet)
(3) 3/4" PVC 90 degree Elbows
(1) 3/4" slip fit to 1/2" threaded reducer
(1) 1/2" threaded coupler
(1) hose threaded to 1/2" reducer (I would recommend using a brass fitting, as it is much more durable. The rotating part tends to pop off of the PVC ones.)
(1) AquaMend Underwater Repair Epoxy Stick
(1) Teflon Tape
(1) PVC Pipe Cement
(1) 3/4" PVC 4 Way Cross Section***
(2) 3/4" PVC End Cap***
PVC Pipe cutter (or saw)
Groove lock pliers
***Please see UPDATED section for picture of 4 way pipe fitting and end caps
Step 3: Cut the Vertical Piece
Cut the vertical piece of pipe that will hold the entire assembly low over the side of your pool.
Step 4: Add Elbows To Vertical Piece
Add two of the 90 degree elbows to the vertical piece, facing opposite directions.
Step 5: Epoxy Toilet Valve Into 90 degree elbow
Take the AquaMend epoxy out of its tube and cut off approx. 1 inch. Knead it together until a uniform color is achieved. Mold it into a string, and tear it in half. Set one part aside, and roll the other out, using the tube as a rolling pin. Get it long enough to wrap all the way around the threads on the valve. Wrap it on the threads and insert it into the tube as far as it will go. Use the second part you set aside earlier to form a nice, graduated seal on the pipe. Smooth this out with your fingers. Allow to harden for 1 hour before continuing.
