Python Protected Water Changer?

Hello, I want to make a device that I can hang on the side of my tank to change the water. Something with a sponge over the end to avoid sucking up fry and baby shrimps.

So I want to construct something made of PVC pipe that I can attach to my python, and I can just hang it over the side of the tank and drain without paying close attention.

I'm wondering how to attach pipe connectors and what size pipe would be recomended? 3/4th inch? Should I use pipe glue or go a different route? Would it be better to pickup threaded fittings?

I have a picture of a similar device in my Guide. Use 3/4" tubing. Of course you need to use PVC cement or it will leak.

Everything just glues together. You should be able to find everything you need at the BORG.

Of course if you are filling the tank you will need to pay attention.

Just made a DIY python myself a couple of weeks ago. I think I spent as much on the parts as it would have been to buy one but what fun would that have been. I found this thread very helpful:

Usually the people at Home Depot and Lowes are pretty helpful if you're not sure what parts you need.

You mean something like this???



Since I don't use my intake from my Eheim 2128 and use the Eheim Installation sets instead, I decided to put the original Eheim intake to good use for my water changes/filling.

This is what I used...
- Eheim 16mm/22mm intake tube
- 2" piece of Eheim 16/22mm tubing
- 2" piece of Python tubing.placed some tubing (Python and Eheim tubing)
- A 1/2" (size of Python tubing) to 5/8" barb (size of Eheim tubing)
- Python connecters
- Pre-filter sponge, used from my Mag drive pump

I cut the intake tube and connected the appropriate tubing and connectors, which look like this...



After it's assembled, it will look like this...

Yea, thats what I want to make but I don't have the eheim parts so i plan to make it out of PVC. Went to lowes and found the proper size threaded pipe fitting that can screw/unscrew from teh python, but there is no Gromit to seal it up...

So I'm guessing it would be better to use the pyton part and some tubing? Then some kind of reducer to go to the pythin tubing? Or will the threaded PVC be enough of a seal without the O-ring?

You can use some aquarium silicone to seal it up if there is no gromit. Then secure it with a wire tie.

What good would a wire tie do on PVC pipe? What I mean is that I was going to use a pipe fitting that threaded into the python right after the valve. So I can change the easy water changer back to gravel vacume by unscrewing it...It's just that there is no gromit in the PVC piece like there is in the python part.

need a picture?
