good learning ...


almost 4 years ago I made my current tank and a significant part of plumbing has been made using flex hose that Lowes or Menards has, if I recall correctly, for hot tubes blow jets. It is about $9 for 10' is white and a 5/8" size.
Big mistake ! A few months ago one segment feeding the scrubber cracked and this week another line that was not even flexed like previous one cracked as well.
I took a good look and it is obvious that this material is aging and loses its flexibility. At that point it is not strong enough to sustain the water flow. Today I replaced every single line and I can tell you it cracked in my hands just handling.
Fortunately, I got probably two gallons on my carpet till my controller reacted, but all this story makes me think what's gone happen if someone spills a whole hot tube.
Here are some pictures,

hope it helps,

There is a reason why it doesn't pay to cheap out when it comes to plumbing.

Spend the money, do it right, do it once.

I'm impressed it lasted 4 years though...

I don't use that kind of pipe. But I also have a flexible PVC shower pan liner (Lowes or HD) in the bottom of my stand to catch and contain any leaks.
