I have hundreds of photos of schedule 10 pipe corroded away without them. In twelve years or less.

I’ve put a low water level switch on every tank I’ve done for the last 39 years. Then the vendor tells me, I’m the only one buying them. Same as end seal couplings in dry systems, vendor told us we were the only contractor that ever bought them, but that’s a different problem.

Go online and find a company called Warrick Controls. They make liquid level systems using rigid electrodes and wire suspended ones, and you can custom arrange two or three or four or even five electrodes in a single housing to control pump up pump down and signaling for tanks.

I’m starting to wonder if it is really even required. I’ve been told by several vendors that we are the only ones that ever buy them. Looked through the last 2 editions of NFPA 22 and can’t find any reference to a water level switch. Checking the FM guides now.

For whatever reason Potter has this item on backorder until the end of July. We have to be done and off the job by the end of June.
