Okay, so when we first moved into this house, the faucet was "a little out of date" to say the least. So, I went out, and bought a really nice Delta faucet, installed it myself! HOWEVER!!! When I first started keeping fish, I found out that there was an awesome tool, called a "python" that will change the water for you, and is so easy, and not much work. Needless to say, this "python" or any other products like it, don't fit my faucet. So, here I was with quite a problem!
4 tanks - each one 30 gallons or more! (And goldfish in them, no less!)

So, I finally decided to do something because I am tired of being a slave to my tanks!
Here's a picture of my faucet, and how it connects to the sprayer hose underneath the sink. The whole spigot pulls out to be a sprayer.
You can also make this for a "regular" faucet, just use the fittings that match your sink's faucet.

The first step, was finding a fitting to match the threads of my faucet attachment. Then, I attached hose to that part (oh, man, all these technical words are just blowing my mind! is there a way to indicate sarcasm? sorry I can't be more specific!) that's tapered for this size hose. I would have preferred a larger gauge hose, but this is the only type of hardware I could find to match my faucet threads/size.

Then I attached a three way splitter, so I could adjust the water to the correct temperature before sending the water all the way through the hose, and into the tank. The side valve is "open" when I want to test the water temp. There is another valve after this one to stop the flow towards the tank, but that's getting ahead of myself!

One opening has a tapered connection, and the tube is able to just push on. The other connection is just threaded, for a nut to be secured to. We put a cup of hot water in the microwave for 45 seconds, removed it with pot holders (this is very important, even though the water is not visibly boiling, it is just as hot and can burn you.) Then stick the end to be fitted around the threading into the hot water to make it more pliable, and work at putting the tubing around it. I used some clamps on all connections, just to make sure they were secure and wouldn't ever "pop off."

Here is the finished product.

I couldn't find a "good" color that shows up well, but the top caption says
"Temperature Valve
Turn "on" when testing temp
Turn "off" when filling tank"

The bottom caption reads
"Tank Valve
Turn "off" when testing the temperature
Turn "on" when filling tank"

It's important to always have one open while the other is closed. If they are both open, water will flow out both directions, and if they are both closed, water pressure will build up.

-------------------
I'd also like to add (THIS PART IS VERY IMPORTANT!)
I've always used a siphon attached to a garden hose to drain my tanks into the yard. I don't use this to drain my tanks. If I wanted to do that, I would have to switch which valve goes to the tank, and which one tests the temperature to get the appropriate suction to drain a tank. The temperature valve would have to be "in line" with the faucet water running, and the tank valve would have to come off of the side, perpendicular to the tank flow direction.
This is the siphon I use.

I just put the end of the siphon hose (as far as it will go) into a garden hose that is 50 feet long, and dangle it into my yard. The diameters are just right. The other siphon I have, the hose is too big to fit into the garden hose.

Thanks! Does everyone here with "monster tanks" use a water changer similar to this?

Even if I had a thousand-gallon tank I don't think I could be this ingenious! Wow!
 
Oh, I have a question about Prime usage and a water changer system such as this one. I know you dose the tank for the whole tank's capacity before you start adding the chlorinated tap water, but should I also wait a certain period of time before turning the filters back on, to prevent chlorine from killing my beneficial bacteria bed?
It's always been somewhat of a mystery to me as to how sodium thiosulfate works, like...how fast it breaks up the chlorine/chloramine. I know it persists in water for 24 hours, but that's the length of my knowledge.
