Message: [QUOTE="combatwombat, post: 505301, member: 14119"] Well, just my luck. Woke up Friday morning and the pump was off and bog drained down again. Only this time, pump won't restart. Getting quite tired of this. Something tripped the GFCI Thursday night that knocked out the pump. Check valve failed AGAIN (I think debris in the line may have prevented a complete seal). Reminder: I have a variable speed pump w/ onboard controls. Power on pump. Low voltage controls fire up, but motor will only come on line for a second before tripping GFCI. Try another GFCI circuit. Same result. Try non-gfci circuit, now the motor won't come on at all. Call manufacturer. They suggest testing voltage at plug and removing pump from power for several hours to drain capacitors and get pump back to factory settings. Leave it unplugged overnight. Try again, same result. Start disassembling pump to troubleshoot. Pull control module off. F***'n thing is full of water. My guess: I messed up the grade of my overflow path when I mulched over it, reservoir was already full of water w/ no spare capacity, and the failed check valve allowed a rush of water to back flow into the reservoir and overflow into the pump area, partially submerging it. Call manufacturer back: "Yeah it's probably toast." $600 down the drain. But they felt bad for me and said they might be able to find a replacement in the warehouse they'd sell me at cost. Anyway, I'm going to prioritize the bog plumbing fix because I'm really tired of this backflow issue. And I think I've found a solution that won't require undoing rock work and plumbing already buried in the bog. I'm simply going to make a hump in the plumbing outside of the bog that rises above bog water level, stick a tee on the top of the hump and install an air admittance valve. It'll cost me (4) elbows and the associated head pressure, but should solve this problem once and for all and should be a quick retrofit. Credit to Dad for that idea. And if things don't work out with this pump, I'm also seriously considering switching to a submersible, though I haven't found one that ticks all my boxes yet. [/QUOTE]
