Hello, today I went to Camping World to buy a replacement sewer hose as mine has a few pin hole leaks in it. Not knowing much about the fittings, I bought a Dominator hose which has red fittings. The hose part is great! When I finally got back,(an hour and a half away) and try to fit the red fitting to the coach dump valve flange, it did not fit, too small. I asked a bunch of sewer fitting type questions while at Camping World and not having the coach with me, I couldn't measure exactly, they assured me that the sizes they carry are the only ones made and they will fit...... NOT!

What company makes these larger type fittings? Is it Camco? I will still use the Dominator hose as I will cut off the ends that don't fit and fit the original fittings from my old hose to the new hose. The hose is the same diameter as the old leaky hose.
My fittings are thick white PVC type material. Any help would be much appreciated. Thanks, Jennifer
