Water tanks are part of a recreational vehicle's plumbing system. The fresh-water tank isolates fresh drinking and bathing water from the grey tank used for shower and sink drainage and the black tank used for the sewage process. Attachments and fixtures on the tanks at times need to be replaced or repaired. If the piece you need to replace requires gluing, there is a tested method to use for the repair.
Wash and dry both sides of the fitting, and clean the external fitting and the attachment point at the tank.
Rub the fitting's inside edge and the external connection point on the tank with sandpaper. This makes the PVC surface porous and ready to absorb the waterproof PVC glue.
Apply a coat of the glue to each of the sanded areas. Connect the fixtures and give time to dry as per the glue instructions. Wipe away any excess glue from the area before it dries.
Test the connection by pulling it with your hands to ensure it has dried and sealed properly.
