Thank you for visiting Sump Pumps Direct. Systems based on this design have been around for quite some time from various manufacturers and do perform well. The thing that you need to consider is that all manufacturers do recommend that their systems be inspected every 4-6 months to insure that they are operating correctly and when you do need a replacement pump, you are generally bound to the same pump as the original or an updated model that is designed specifically for that system. These pumps are usually available, though it may need a little investigating to locate them. Hope this helps you and may your man cave continue to provide you with many years of enjoyment and pleasant smells! If you have additional questions, please let me know.
