You can pick up a sump pump at just about any home improvement store, and most of them come along with directions that are fairly straightforward. Nevertheless, installing a sump pump is not quite as simple as it seems; there is actually a lot of room for mistakes that can threaten the well-being of the house you are trying to protect with the installation. It is far better to trust a pro for the sump pump installation of one of these pumps. Here is a look at some of the mistakes that you could make when trying to install one of these units on your own and the damages these mistakes can lead to.
Mistake: Not properly installing the check valve.
Potential Damage: The check valve serves the very important purpose of shutting down and turning on the sump pump according to water levels in the receiving hole the pump is placed in. If you do not properly install the check valve, you are going to end up with a pump that will not kick on when water levels are up and will not kick off when the water is gone. Both issues are problematic for obvious reasons.
Mistake: Not sealing the around the PVC outlet line.
Potential Damage: The opening where you put the outlet line through the wall has to be sealed off properly around it. If you do not take the time to use silicone caulking, spray foam insulation, or something else to seal off the opening, you are leaving an access point for pests and leaving an opening where water can actually get inside your home. Even if the opening around the outlet line is minimal, make sure you make an effort to close any gaps.
Mistake: Not channeling the outlet water away from the house.
Potential Damage: The water that is pulled out by the sump pump has to be led away from the house properly, which can take some doing on your part. If you do not create a channel so the water will naturally flow out and away from the house, the water is just going to flow back toward the house and create even more problems with flooding. The natural slope of the ground is not always enough to encourage proper water flow, so you do have to be careful and make sure you dig a channel in the ground to properly route the water.
