About 50,000 miles and over 200 campgrounds with Sewer Solutions. Not one failure. All original parts still in use. With Happy Camper tank treatment we can dump black with NO extra water. Need longer reach - 1" PVC pipe will fit on end of dump fitting. With a couple more PVC fittings we use a Harbor Freight fifty foot 3/4 inch hose when the original 10 foot hose won't reach. Then we resort to 1" PVC for the really long runs. Two gray tanks and only one Sewer Solutions. Need to pump uphill a couple feet. It works. If camp or tank water is used to dump black it only take one gal per ten gal of tank water. Never use extra water to dump gray water. I see others using that much to clean hose. In all the years we have been using it I don't think we lost a drop due to system leaks while dumping.
