About the service
If your control panel shows the black tank is two-thirds full when you just emptied it, or the grey tank reads 'full' just a day after draining — the problem is almost never the tank itself, but the electrode sensors or wiring and panel electronics behind them. I'm a mobile technician specializing in diagnostics and repair of tank level sensors in RVs: I come to your driveway, parking spot, or campground with all my tools so you don't have to tow your vehicle anywhere.
Work starts with complete diagnostics: I check each electrode (typically three per tank — full, one-third, two-thirds) with a multimeter for circuit continuity and resistance, inspect external contacts for toilet paper residue and debris buildup, trace wiring to the panel connector block for corrosion or rodent damage, and test the panel itself by substituting a known good signal. Usually within thirty to forty-five minutes it becomes clear: whether electrodes are clogged, a wire is broken, there's poor grounding, or the panel board is faulty.
Depending on what I find, I offer repair options: cleaning and reinstalling external tape-style electrodes, replacing faulty sensors with capacitive or ultrasonic sensor tapes that read level through the tank wall and are far less prone to contamination than the standard resistive electrodes installed by most manufacturers, repairing or replacing damaged wiring sections with marine-grade sealed connectors, or calibrating or replacing the display panel itself. For owners tired of chasing false readings season after season, I offer complete conversion to sensor tapes — this solves the electrode contact problem once and for all.
After each visit I provide a written summary — what was checked, what was found, what was replaced or repaired, plus before-and-after photos of the wiring. I carry typical electrodes, wire, panel fuses, and a stock of universal sensor tapes in my service vehicle, so I resolve most jobs in a single visit without needing a return trip. I've repaired sensor systems on motorhomes, fifth wheels, and travel trailers from various panel manufacturers and am always ready to discuss your symptoms over the phone before booking to honestly assess the likely cause.
