Chickens need water but the conventional water containers for chickens allow water to go stagnant and accumulate back wash when the chickens drink. So you are forever changing and cleaning their water.

The idea behind this system is that there is no way for any back wash to enter the water and the water staying fresh.

To start with you need the following items:
- PVC down pipe (2 lengths to suit your situation)
- PVC 90 deg bend to fit the down pipe
- 2 end caps to fit your down pipe
- PVC cement
- watering nipples
- rubber gloves for protection
- 2-3 x wall brackets to fit your down pipe and screws (not shown in picture)

Step 1: Bottom Pipe

We will make an L shape with the two length of PVC pipes with the watering nipples aligned along the bottom of the L shape.
Pick one length of PVC pipe to become the bottom part of the L shape. If necessary cut to size so it will fit the location where you are planning to install this system.

Now drill holes along a straight line. Leave enough space on either end to fit an end cap and the 90 deg bend without overlapping any holes. The diameter of the holes should you slightly smaller than the diameter of the threaded part of the watering nipples.

I generally space the holes far enough apart so one to two chickens can get to each watering nipple at the same time.

Step 2: End Cap Along Bottom

Now smear a coating of the PVC cement around one end of the bottom pipe and the inside of one of the pipe ends.
Once they are both coated put the pipe end onto the coated pipe end and push on all the way. The PVC cement I used sets pretty quickly and takes a little longer to cure.

Read the instructions that come with your PVC cement.

Step 3: Completing the L Shape.

Now complete the L shape by glueing on the 90 deg bend and the upright pipe.

Hints for later:

Again cut the upright pipe to length before glueing so that the complete L shape fits the spot where you intend to install this.

When glueing on the 90 deg bend to the bottom work it such that the holes for the watering nipples are along the bottom and slight pointing towards the front; away from any wall that you might install this contraption on. This will make it easier for your chickens to reach the watering nipples.

Don't glue on the second pipe end! It will act as a removable lid to allow filling of this watering system and keep dust and bugs out of the water.

Step 4: Installing Nipples

Now take your watering nipples and screw them tightly into the holes you've drilled earlier. If they aren't tight enough you will have continuous dripping which you don't want. The purpose of these nipples is to keep the water in until a chicken worries at the nipple.

Step 5: Final Installation and Happy Chooks

Now install your L shaped pipe construction on a wall with the watering nipples along the bottom of the L using the brackets and screws not shown in the intro.

It won't take long for your chickens to work out how to drink from the nipples. I showed our chickens by wiggling the nipples such that drops of water came out. This caught the interest of the chickens and they worked it out from there.

Now you don't have to waste any more water because of chicken back wash making your water dirty!
