What's the best detector & alarm for a back flow valve that has been installed by the utility?
Waste water cannot exit when valve is closed giving a risk of sewage from inside overflowing in basement. Sewer line (Naturally) is below grade and not readily accessible. There is a drain with P trap subject to collecting rain water. It may be a source for detecting sewer backup upon an overflow. What would be the best detector to fit?
Hey there Tom, we have an article on one of our favorite backwater valves here, but this is really a full system - so if you wish to install a simple alarm to your existing system, we would probably take a look here for alarm product comparisons and availability. It's a great idea to have one of these alarms fitted if you have a finished basement or are finishing a basement to prevent flooding.
