Ok guys, I've had a ton of requests to show this thing over the past six months or so, so here it is. This thing is incredibly cheap and easy to build, my total investment was a hair over $40, and its worth its weight in gold. I'm not even going to include blueprints as to how to do it because its that simple. All piping in this is 3/4" ID sch. 40 pvc. I'm sharing this to give you an idea how to make your own that will suit your needs.

What you'll need:
Three ball valves
A 90* T junction
Some sort of piping to connect this contraption to the filter outlet. I used flexible PVC.
Worm clamps
A brass PVC to garden hose adaptor thingy
Some PVC glue and/or brass male/male connectors. I used brass male/male connectors to put all of the pieces together, but if I had it to do over again, I'd use glue.

Pic 1- This is how the cheatin' easy water changer is most of the time. The in-line ball valves are open and the drain is closed. You can see fairly well the PVC to garden hose adaptor thingy. One end has the same threading as the PCV on the ball valve, the other is the same as a garden hose so you can attach a hose.

Pic 2- The first thing you need to do is attach the hose. I made my own hose out of clear 3/4" ID hosing so I can see what's going on in the hose. After you attach it to the drain, put the other end of the hose where ever you pump water, I put it in the sink in winter and out the window in summer.

Pic 3- Once you have the hose where you want the water to go, FIRST open the drain ball valve and THEN close the outlet ball valve. This will drain your water.

Pic 5- Once your tank is drained to the point that you're happy, shut off your filter. Then walk over to the sink and attach the hose to the faucet.

Pic 6- After you attach the hose to the faucet, go back to the tank and shut the ball valve between the drain and the filter and open the ball valve between the drain and the outlet. This will allow the water from your faucet to enter the tank through the filter's outlet. Once that is open, go turn on your faucet, add your chemicals, and wait for your tank to fill!

Truly an amazing idea your onto chix. I may consider this myself this year once iv saved up enough for the next upgrade.
 
Seems like the next best thing to a constant change setup. Thanks for sharing.

What is the black stuff on the joints? Are they not glued with pvc cement?

I used threaded brass fixings with teflon tape to join the pieces. As an added safety measure, I added that black pipe repair tape stuff to it. Supposedly it's as strong as sch 40 pvc. I forget what its actually called.

If I had to do this all over again, I would cement everything together. It would have made life sooooo much easier.
 
this may sound stupid but straight from the tap how do you get the temp right before it gets in the tank?

Let the water warm up before I attach the hose. Once its warmed up, I let it run and adjust the hot and cold until its roughly the same as the tank water. Once its about the same, I take note of where the knobs are, turn the faucet off, attach the hose and turn it back on to the previous setting. I then walk over to the tank and feel the water going into the tank and make adjustments as necessary to maintain the ideal temperature.
 
Very cool. Almost identical to what I did when I had the pool pond going.
 
Bear with me, as I ain't very bright. Is this part of your FX5 set up? If not, how is it all that different from a Python? What are the hoses connected to that are running across the top that have the valves in them?

Everyone has the right to be stupid (ME), but do so many of you have to abuse that right?
