Protecting Flood Prevention Devices & Your Basement
To keep your flood prevention devices in good working order, it is essential to maintain them according to the manufacturer’s directions.
When installing a backwater valve, consider including an alarm, so that you know when the device is activated. When your backwater valve is activated, it works to keep sewer water from backing up into your basement, but it also keeps wastewater from your home from flowing to the sewer. When your backwater valve is activated, any water sent down the drain (through toilets, sinks laundry etc.), may end up in your basement.
As rainstorms and power outages can accompany one another, you may also want to consider battery-power back-up for your sump pump.
