Sorry to be a pest. Just trying to learn here. Last december, I posted a question about a suspicious burried underground pressure tank that is now over 14 years old, and later found that the tank was at that time still good. A blown o-ring was found in the well, and also some leaking fittings due to a pressure switch sticking. Now, another leak came up, and upon digging out the burried pressure tank (a Goulds V200B), it was found to have a hole rusted through right at the pipe fitting, although the bladder is still sound. The underground tank was removed, the hole in the front yard filled in, and two challenger PC-144 tanks are now ganged together under my house in the crawl space. The new pressure switch is now between the two tanks, not in the well casing as it was before, and it does have a relief valve now, though that is not required by code here. Was just an option that I wanted. I have never heard of a challenger tank, and after doing some research, Ive found they are made by flexcon industries. I remember several people saying something about flexcon here in the past, but Im curious on the challengers, as Ive never heard of them. My questions; Are the challenger tanks as decent as the seller has claimed, or is this a "cheapened" version of the flexcons that we've talked about here? I got a great deal on two of them, so if theyre good quality 9as they appear to be), then Im super mega happy! My other question now; the tanks are installed laying down. The guy explained (hopefully not lying to me) that not all bladder tanks are bladder tanks, that the cheap ones use a bladder bag, which is like a balloon, and they have to stand upright, otherwise the balloon chaffs on the tank sides as it inflates and deflates with water. However, he says that the good tanks (like the challenger, according to him) use rubber diaphrams which are like a rubber saucer clamped to the inside of the tank, that they will last longer, and that the diaphram tanks can be used standing up or laying down because the diaphram cannot rub against the tank wall. Does this sound right? My well is feeding two other houses, so I just want to make sure that this was done right, though everyone including myself does seem happy with the water flow.
