Our RV site sewer cap is a watertight locking cap. Sewer cap is installed by hammering it in place either above or below grade. Bottom is not threaded. It is held secure by 10 internal watertight concentric rings and the UV protective gasket creates a watertight compression seal. Great for areas that flood. Sewer lid is not self-closing. Can be padlocked or zip tied for security. Fits Schedule 40 and 80 PVC pipe. For SWB or SW35 thinwall pipe, you will need a 4 x 4 bushing for our RV site sewer cap to fit your pipe.
