Aqua-Magic VI is a permanent RV toilet. Space saving design allows for the closest possible mounting to the wall. Foot flush positioned for minimal floor space interference. Available in high or low profiles to fit your specific space requirements. High profile offers taller seating height for maximum comfort. ADA compliant 18-inch seat height. Caution: Do not use stiff brushes or homemade products to clean or lubricate the valve and seal, as these will damage the seals and surfaces, causing odors to escape from holding tanks. Thetford recommends using Aqua-Clean and toilet seal lubricants.
