DIY plans for Coil Denitrator

Step 4
After a few days to allow the airline to adjust to the new shape, it is now to time for the next step.
the next thing that needs to happen is to connect the toilet flange to the 3 foot 3 inch PVC pipe.
this toilet flange acts as a stand for the tube and allows it to stand on its' own.
the trick is to have the air tubing down at the bottom of the tube.
What I did was have the 4 foot piece of pvc with the airline wrapped on it inside the 3 inch PVC pipe and then undo the duct tape on the end of it so the end of the airline inside the 3 inch pvc. I then glued the flange onto the end of the 3 foot 3 inch tube. ensure you turn it abit so that the PVC glue settle properly.

Step 5 (you need 2 people for this part.)
I then put the flange on the ground so that the 3 foot PVC was straight up and down.
I then removed the tape off the end of the top of the airline tube.
ENSURE THAT YOU HOLD ONTO THE END OR ELSE THE TUBING WILL START UNRAVELING.
One person then need to start basically pulling out the 4 foot piece of 1.5 inch pvc out of the 3 inch pvc while pushing down on the airline tubing.
What you are doing is basically pushing the bottom end of the tubing off the pvc into the bottom of the 3 inch pvc.
as you pull more and more of the 4 foot piece out, more and more of the air tubing should be coming off of the 1.5 inch PVC and lining the inside of the 3 inch PVC as it goes up.
At the same time, the other person needs to be putting the bacteria media down the end of the tube so that it end ups in the bottom of the big PVC pipe, filling it the 3 inch PVC and pushing the airline to the inside wall of the 3 inch PVC Pipe.
you continue to do this till all of the 1/4 inch airline tubing is inside of the 3 foot 3 inch PVC pipe and the 3 inch pipe is filled with the bacteria media.

Step 6
the next step is to finish off the top of the denitrator
To do this you need to take the remaining airline (you need about 6 inches extra) and push it up throught the valve that you drilled out and up through to the top of the cap with about 3 or 4 inches outside the top of the cap.
Then using PVC glue, glue the top cap onto the 3 foot 3 inch PVC.
you have now completed the Denitrator.

The most difficult part of this project is to drill and thread the pvc cap for the 1/4 inch valves.
You will need the appropriate tap and die set (or talk really nicely to someone that does) to thread the holes on the cap.

Say, does anyone in Calgary have the appropriate tap and die set? *hint hint*

You don't need the die part just the tap part. It is a NPT1/4-18 tap and it's not going to be included in the typical tap/die set that you see at Can-Tire. They are fairly inexpensive and the drill size is 7/16". Mine has received a fatal impact with a concrete floor and will be replaced when my brain ram starts functioning again.
