I bought this so that I could add it to an existing python, but it came with a fitting on one end that would not allow it to be installed inline. This did not work for me and I am very disappointed.

My dog chewed it up before I was able to use it xD

I was tired of the bulb I had being too squishy and not pulling through my improvised system.
When water finally would flow I would get a nasty leak out of the fittings around the bulb. ENTER THIS ONE!
I had to replum the main hose and still havent found the best place in my system to permanently house the python bulb. I have to basically stand at the bucket at the end of my run instead of the tank I'm trying to clean or else I end up with an empty bucket and a very wet floor.
