About the service
If your black tank sensors show "full" even after draining, the drain valve leaks, and unpleasant odor won't go away with any products through the toilet — it's almost always not the tank itself, but a buildup on the walls that regular gravity drainage doesn't remove. I offer a mobile service for flushing the black tank and servicing the sewage system of an RV: I bring an autonomous high-pressure unit, a supply of clean water and all necessary fittings to service your RV right where it stands — at a campground, storage facility or in your yard.
Work begins with complete gravity drainage, after which I connect a flush nozzle through the toilet or separate flush port and run several high-pressure cycles until the outflow water is clean. This breaks down the buildup of paper and solid waste that sticks to tank walls and "clogs" the capacitive sensors — this is the main reason for incorrect level readings. At the same time I inspect and clean the sensor strips, check the drain valve seals for wear, lubricate the valve mechanism and test it for tightness. If the valve is cracked or the seal has failed, I'll tell you exactly what parts are needed, and often can replace the standard valve cartridge on the spot.
Upon request I also flush the gray tank, treat both tanks with an enzyme-based composition safe for septic systems and holding tanks, and check the grinder or pump if installed. Each job ends with a final flush of the drain area and hose connections outside, so there's no dirt left behind. I work with my own water container and runoff collection system so nothing goes where it shouldn't, and strictly follow sanitation rules of campgrounds and parking areas.
This service is especially useful before winterization, before a long trip, after purchasing a used RV with unknown tank history, or simply on a seasonal schedule so sensors show the truth and there's no smell in the bathroom. I have years of practical experience servicing RVs, my own equipment and clear fixed pricing before work begins — no surprises and no hourly meter. Write me your camper type and location — we'll coordinate the time.
