I gave my friend a relatively new Rio 2100 (I gave him mine because his was having problems, go figure), he had used the pump for his main return pump (for about 2 months, and the pump maybe had 6 months of total usage).
To make a long story short: He went on vacation/hunting trip and the pump burned where it connected into the surge protector (that didn't protect, and the breakers didn't trip?). Thankfully his wife showed back up to the house which was filed with smoke, called the Fire Dept., they came out and took care of the problem.
After the fire:
His fish were dead or about to die.
His sump cracked & burned due to the heat.
His heater had some fun too once the sump was empty.
All of the electrictal cords to every piece of equipment had the plug burned, but it most defineately started at the Rio (as per the F.D.).
The carpet is defineately not new anymore.
A new odor was in the air, smoke.
The fire was caught before the integrity of the stand was compromised, got to love Natural Woodcrafters.
Anyway, thankfully I still have a friend and he still has a house!
I have also had 2 Rios go out on my own, and I got shocked by one of them.
A total of 4 Rios down, got to love them, LOL. I have since decided to put my money elsewhere.
Here is a Rio Joke for you: What do you get when one puts Rios on a Wavemaker?????
TROUBLE!!!!!
