DIYer, not in the trades
For years, I've been using an el cheapo Zircon Leak Alert http://www.zircon.com/products/more_leak_alert.html that I had modified with a remote probe. I soldered an RJ11 jack to it so that I could use a 25 foot phone cord to another RJ11 jack on the cover of my sump pit. I then drove two long stainless steel deck screws through the lid to act as probes. I placed the Leak Alert up in the living space next to the hot water tank.
Over the years, the system has degraded and started false-alarming. First I had moisture condense on the underside of the sump pit cover and had to insulate all but the tips of the screws. Then the cheap phone wire got damp and needed to be replaced. Now the local sensor on the Leak Alert started false-alarming. Unplugging the phone cord would not silence it.
Sure, I could break into the piggy bank and find $7 for another one but I wonder if there are any other reasonably priced units that can be chained together so that if one goes off, they all go off like wired smoke alarms do.
