Sump pumps are available in two types: pedestal and submersible. A battery-powered system can provide up to 18 hours of backup time. Pedestal sump pumps are usually cheaper, but are noisier. This can be a tricky proposition, as you don't want to overdo it, but the best way to do this is to do a little research. You'll need a wrench to help you do this. You might be surprised at what you find. They can last for several years if properly maintained. In addition, a pump helps prevent mold growth, which can damage walls and warp wood. The wrong placement can result in significant leakage. A local plumbing company may be able to help you with this process. Having a basement with moisture is no fun, and it can lead to major property damage. As well, your final price will depend on how complex the installation is.
