TIFFIN MOTORHOMES –ALLEGRO RED® Chapter 11 PLUMBING & BATH FIXTURESWASTE WATER SYSTEMSGeneral InformationThe waste drainage system was designed to provide adequate and safe storage and/or disposal of waste materials. Allof the materials used in the fabrication of this system are tested by a nationally-recognized testing laboratory. Thedrainage system uses plastic piping and fittings connected to the sinks, toilet, and holding tanks.This plumbing permits the drainage of these fixtures to an outside termination. The vehicle should be reasonably levelfor best operation of both of the wastewater systems (there are two, separate wastewater systems). The gray-watersystem is for wastewater from the sinks and shower. The black-water system is for sewage waste from the toilet. Eachwastewater tank has its own control valve and both drain through a common sewer-drain hose.ToiletThe toilet (Figure 11-10) in your motor home may be a china toilet equipped with a sprayattachment. The toilet operates with water from either the fresh water tank with the waterpump “on” or the city water supply. Before using the toilet, add water to the bottom ofthe tank. Refer to the “BLACK WATER TANK” instructions elsewhere in this chapter.The toilet flushes waste directly into the black-water holding tank. The toilet uses highvelocitywater injection to produce swirl effect in the bowl. The greatest problem thatcauses stool solids to accumulate in the holding tank islack of liquids. It is imperative that you use as much water as possible when flushing toprevent tissue and other solids from clogging the holding tank outlet.Figure 11-10. ToiletWhen using your toilet, it is wise to fill the toilet . full of water—this will help wash thesolids away from directly below the toilet and to assure complete dumping of the holdingtank. To add water to the toilet bowl, lift or raise the flush lever until the desired water level is reached. To flush thetoilet, push down on the lever until the water swirls. A small amount of water should remain in the bowl.The toilet should be cleaned regularly for maximum sanitation and operational efficiency. Clean the toilet bowl with amild bathroom cleaner. DO NOT USE CHLORINE OR CAUSTIC CHEMICALS, SUCH AS LAUNDRY BLEACH ORDRAIN-OPENING TYPES, AS THEY WILL DAMAGE THE SEALS IN THE TOILET AND DUMP VALVES.Refer to the toilet-manufacturer’s owner’s manual in your Allegro RED Owner’s Information Package for completeinstructions and a detailed troubleshooting guide.11-7
