(it used to be nearly every day at one stage)
Rich, that's why I suggested a UPS (Uninterruptable Power Supply) - it will take the surges out and, if the power does go off, it will still run the pump(s) for a while - depending on the UPS's battery life.
I have one on my main PC because some years ago, I was working on a CAD drawing for Uni and hadn't done a save for almost an hour. The power went off and I had wasted Christmas Day: I could have just wasted time and watched TV all day for the work I got done!
There again - I was watching TV on Christmas Day about ten years ago; the power dropped and came back, but the TV died - a bit like your pump! So I now have "surge protectors" on both TV sockets (they plug into the mains socket and the TV plugs into them) and the UPS on the computer often "peeps" - a sign that power has dropped out, repeated peeps say the computer is running from the UPS. The only problem now is that when there's a power cut, the router goes off, so I can't get on the interweb!
We used a lot when I was working (on student placement) for a chemical manufacturer - if their power went off, the plant computers (or PLCs to be exact) couldn't remember how far through a process they had got and the batch could be ruined if the operators weren't on the ball. I know this because some idiot of a placement student pulled a wrong plug in an instrument cabinet
They could only blame themselves - someone had swapped a four way adapter for a six way one and didn't update the drawings to say what was plugged into which socket or mark the plugs/cables!

The outside pipework looks more impressive than the ones I've seen over here - they just used one long length of ordinary alkathene water pipe (the blue stuff) and had great fun trying to get it in without kinking it!
