Hi Max,
In my garage under the house it has been flooded twice over the 35 years it has been there. Once I was there and was watching the water come up and I could feel the pump running and I just thought it couldn't keep up. Turns out the pump was air locked and was doing nothing. Ever since then all my pumps lay on their sides and can't air lock. The second time I have no idea what happened but I can see the second watermark on the doors. Now I have 2 240 volt pumps in that pit with the switches at different heights so if the first pump fails the second can take over. I also have a 12 volt pump in the same pit as a backup if the power fails and it also alarms upstairs so we know quickly if there is a problem. Finally got the float switches down there to work properly only a few years ago. Was always panic stations when it rained before to make sure they were working.
The casting cement is the one in the pic on the left, the stuff I have been getting (just ordered another 5 x100g) usually doesn't have any writing on it just A and B or just Chinese writing. In the last hour I found something it wouldn't stick, it is a plastic float switch float and it just didn't take to it. I also found it wouldn't stick fish pond liner together but not sure if it was the way I tried it. Regarding the bit of tranny line I stuck into the Tecumesh carby this morning I went to pull the fuel hose off it and the hose ripped but the pipe didn't move, It was only a bit of plastic hose but I pulled hard enough for it to just tear off
