If the sump frequently has standing water and water in the tank is an issue, consider installing 4” Red Jacket® Stainless Steel Riser Pipes, Type 304, NPT thread, in all new and reconfigured submersible turbine pump applications.
Red Jacket Stainless Steel Riser Pipes address water intrusion at tank top interfaces due to accelerated corrosion of riser pipe threads in damp sumps. They replace standard 4” riser pipes, and are available in 7.5″, 10.5″, 12.5”, 15.5″, 19.5″, and 27.5″ lengths.
