Televised ducts under slab floor. Ducts are concrete ducts with metal fittings and connections that are rusted and allowing water to enter the system at times of heavy rains. Downspouts are not extended away from the house and the paver walkway allows for pulling next to the house. Suggest extending all downspouts with solid downspout piping and also redoing the paver walkway to allow for better water run off. Possible sump pit and pump in front of the house if water still persists. After water issue is resolved the ducts should be spray lined with Duct Armor duct lining material.
