RV repair facilities work on black water tanks at a high cost-Depending on the repair situation, ranging from hundreds to thousands of dollars-Because they\'re going to take care of your sewage.Removing, repairing and replacing the RV black water tank is an unpleasant job and takes at least a day, but cost savings make the job well worth doing on your own.Explain the difficulties: challenge the empty, and flush out the black water and gray water tank.Close the urban water supply connection with RV and RV pumps.Disconnect the water pipe entering the rear of the toilet.Remove the nut from the closet bolt located at the bottom of the toilet using 12-1Inch socket wrench.Lift the toilet from the bolt.Peel the toilet washer off the flange and discard it.When you reinstall the black tank, install a new toilet washer.Screw the screws that fix the flange on the floor with a screwdriver.Reverse flange counter-Pull clockwise or up and remove it from the black water tank according to the installation method.If the flange is already bonded in place, please cut it off using a hacksaw and re-cutWhen you reinstall the black tank, cement it in place.Climb onto the roof of the RV and remove the black water tank vent cover.Remove the ventilation pipe from the black water tank.For this reason, unscrew the air pipe that leads directly to the black water tank.If the vent pipe is not unscrewed, it is likely to be a wet vent (the vent shared with the sink) or a vent bent before encountering a black tank.If you have a wet or curved ventilation pipe, remove it at the nearest accessible point it meets with the black tank.To find an accessible point, get up and down from the RV and check out the cabinets in the RV and the pipes under the sink.Cut off the gas pipe with a hacksaw.The cut vent pipe needs to be reinstalledThe black tank will solidify when reinstalled.Disassemble the sensor and probe connected to the outside of the black water tank.Remove the discharge valve assembly.Most of the unloading valve assembly unscrew the screw and remove it using a screwdriver.However, some dump components have been solidified in place.If cement, use a steel saw to cut behind the dump valve assembly and separate it from the black water tank.Upon re-Installation of black water tank, re-Cement the dump assembly in place.Check the black tank to determine how it is installed in the RV.Some black water tanks are installed under the RV and are secured in place by straps or metal bands.Other tanks are set in compartments, either fixed in place with wooden blocks or not fixed at all.Pull out the black tank in the compartment and remove the block of wood first if necessary.Before removing the support band or strap, support the black water tank installed under the RV with the floor jack.After removing the strap or strap, slowly put down the Jack and bring the water tank to the ground.The \"tips and warnings\" article by Rose KiviRose kiivi has been written for more than 10 years.She has a background in the area of care, wildlife restoration and habitat protection.Kivi has written educational textbooks, patient care brochures, animal husbandry guides, outdoor survival manuals, and has written contributors to two books in Uncle John\'s Bathroom Reader series.
