I used the pump-out at our club today for the first time (only previously did pump-outs at a nearby commercial marina). My deck-fill was too small for the available plastic 1 1/2" fitting on the suction pump head, and the 1 1/4" fitting was too small to thread in properly - it did barely fit into the deck-fill and allowed enough suction for the pump to do it's job (albeit slowly because of the imperfect fit).
Does anyone know the actual specs of our deck-fills? ... internal diameter and thread size?
