2 years ago I cleaned my cartridge filter and then turned on my 3 HP VSP and it always starts up full speed. I tell ya now, that thing can flat out pump some water. If my house ever catches on fire, I can use my pool and pump for fire fighting.
Anyways.....
A couple minutes later I hear a god awful noise, I went around the corner to where the equip pad is and the sight I saw made me remember that when I put the metal band back on the filter, I had forgotten to tighten it.
The pressure blew the top clean off of the filter and broke my pressure gauge. No clue how high in the air my filter top blasted, but I wish I had seen in happen. Water was going everywhere! On the bright side. the hunt for a new pressure gauge led me to the high class glycerine filled one which I have now.
oops!
