Always check your sump pump for proper function. Especially when snow starts to melt and the spring rains come. This is why we install clear lids.
Here are some very important reminders when it comes to sump pumps. 1, always remove your small extension hose in the late fall. If you do not any water in the hose can quickly freeze and block any more water that may need to be pumped out. Even though we may have a thaw period or some rain. Many pumps will activate in the winter and if the hose is froze you will get water in your basement. The rubber coupler, or check valve can come off because of the back pressure created with the frozen hose. Just leave the hose off or put on a minimum 3 inch solid pipe for winter months. 2, make sure you have a way of checking the water level in your pit. We use clear lids so you can see in the pit. I don’t mean lift up the float and activate the pump, but just be able to check the water level in the pump. Especially when there is rain, or a winter thaw. If the water rose enough to activate the pump and it is running without water being taken out you probably have a frozen pipe outside.
