Step 1: What You Will Need:
2 - End caps.
1 - T
Enough 1/2 inch pipe to connect them together.
You may also need a 45 Degree elbow. Don't get one unless you know you need one.
You will see why in a little bit.
Since there is no real pressure to speak of you won't need to glue them together.
Step 2: Let's Get Started.
First cut two peaces of plastic pipe about 2 1/4 inches in length. Insert them into the end caps and seat them as far as they will go.
Make sure they are seated all the way.
Step 3: Drilling the Holes.
You can now drill the holes for the fountains. Drill each hole into the end caps and into the pipe. Angle the holes so that the streams of water will come toward each other. Again the angle is not critical. Make it as close to the picture as you can is good enough. Make sure you clean up any burrs or drill shavings from your holes and then take out your drill bit and insert the back end of the drill bit into each hole to make sure the hole in the end cap and the pipe are aligned. Also your drill bit will serve as a handle for your next step.
Step 4: Do You Need a 45 Degree Angle?
Step 5: Final Assembly and Adjustment
Go ahead and assemble the peaces together but do not seat them all the way yet, The holes will need to be adjusted.
Take the drill bit and insert the back end into each hole and adjust the holes so that when the center part of the T fitting or the 45 degree elbow is seated over the aerator of the faucet, the two water streams will come together as in the picture in the previous step.
Once that adjustment is complete, you can push everything together and seat the fittings all the way.
Your done! Now you're ready for your next bout with sore eyes.
Tips of use:
Leave your eye washer near the sink in a place where you can find it with your eyes shut. When you really need it that is probably how you will be looking for it. The same goes for using it. Learn to set it up and use it as though you were blind.
And lastly, this is not a substitute for a real emergency eye wash. If you are a DIYr and whatever you are DIYing involves something that could get into your eyes, you are better off with a real emergency eye wash station.
