For a week or so now, I have a leak in my Challenger pump. Water is coming from in between the volute and back seal plate, up past the steel clamp. I assumed it was the seal plate as I have not replaced it in 10 years and I knew there was a small crack (1/2") in it. Today I replaced the seal plate and it seems that the amount of water streaming out of it now though is not just a drip but like a faucet just cracked open. I have replaced the volute portion some years back due to it bursting, and I can find no defect in it. Does the volute warp over time that may be causing this leak? The steel band is as tight as it goes...it is as if the band cannot bring the volute and seal plate tight enough to form a watertight seal...
Any input from experienced Pentair Challenger high head pump owners would be appreciated.
