You might be surprised at what you find. But if your pump fails, you could end up with significant flooding. The pit should be at least 22 inches deep. Here are some ways to do so. A reputable company can even do it for you. In addition, a properly installed sump can protect your home from a serious leak. Depending on your preferences, you might opt for a DIY or for the pricier option, hire a professional to do it for you. Finally, you'll need some PVC cement to finish the job. As well, your final price will depend on how complex the installation is. Fortunately, it's a relatively simple process to retrofit your home. For example, do you have a French drain? In addition to a sump pump, a French drain is a very useful water drainage system for your basement. Many times, the water damage that comes with flooding can be costly. Once you have found a suitable location for the sump pit, you should excavate the area and make a hole. Then, you'll need some primer to help seal the ends of the pipe. They also take up more space than their submersible counterparts.
