The longevity of the sump pump is difficult to dertermine as it depends on several factors, but in general their track record is very good which is why the Hydromatic pumps are among the top selling sump pumps. As the cost of the pump will be over $75.00, shipping will be included in the price. Neither pump comes with a stand and if at all possible, it is always good practice to clean out the sump pit. Both pumps can be purchased directly from us and I have copied the link to the battery back up pump below: https://www.wahlwater.com/Sump-Pump-12V-Automatic-Backup-115V-Residential-Hydromatic-FG-2200_p_1113.html
