This model also features a built-in check valve that prevents backflow of water into the pump, ensuring that it remains free of debris and maintains optimal performance. The pump is easy to install, with a simple wiring harness and clear instructions included in the package.

Overall, the Attwood Shower Sump Mk2 800 is an ideal solution for RV owners seeking a high-capacity, reliable, and efficient shower pump. Its durable construction, powerful performance, and convenient features make it a top choice for those looking to upgrade their RV shower system.
