It's not a hose - it's solid PVC pipe.
When the actual manufacturer tells you your best bet is a rubber mallet and a little luck, it's rather disconcerting. Plus the "you won't be able to get the pipe out again" bugs me - we want to be able to easily store this, which will be more difficult with a piece of PVC sticking out of the side. We'll probably just use a short piece and clamp a hose to it, but still. Ugh.
@combatwombat - I considered exactly that. The one difference is the quality of the box. This one is built to withstand sun, heat, cold, etc. I've used off the shelf rubbermaid for other outdoor projects and find I get about a year out of them before they start to fall to pieces.
This filter also comes with 6 Matala filter pads - 2 green, 2 blue, 2 black. Price those out - it's about $200 just for the filter pads. The whole filter set up was $199. As annoying as this whole situation is, we will probably bite the bullet and buy it again. And yes - they are happy to send us the correct model. I'm just annoyed. They advertise this filter as "Plug and Play". Ummmm... no! haha!
