Water Heater Bypass System; Freshwater Lines - Tiffin Motorhomes Allegro Bus 2016 Owner's Manual

WATER HEATER BYPASS SYSTEM

The water heater bypass valve (Figure 12-8) is located in
the outside utility compartment. This process is performed
when winterizing your motorhome. Using the bypass valve
will keep antifreeze out of the water heater when winteriz-
ing the motorhome.
Draining the water heater during winterizing is a MUST.

FRESHWATER LINES

Check all of the plumbing connections for leaks at least on an annual basis.
If the water pump runs when all faucets are turned "off, " check for a possible leak. Be sure that the drain
valves are closed. Connections at the kitchen and bathroom faucets normally seal by hand-tightening
them and then making an additional half-turn with a wrench.
If a fitting leak persists, disconnect it completely and visually inspect it for mineral deposits or foreign
material stuck on the sealing surfaces. Clean the surfaces thoroughly and reinstall the fitting. Take the
motorhome to an authorized Tiffin Motorhomes service center for additional repairs if the water sys-
tem continues to leak.
Follow the winterizing instructions given in Chapter 16 to reduce risk of leaks caused by cracks from
freezing pipes. Left unchecked, freezing damage can be extensive and expensive.
SANITIZING
To assure complete disinfecting of the freshwater system, it is recommended that the following proce-
dures be performed on a new system, on one that has not been used for a length of time, or one that
may have become contaminated. This procedure is also recommended before long periods of storage,
such as during the winter months:
1. Drain the freshwater tank by opening the drain valve. All of the faucets should be in the closed or
"off " position.
2. Prepare a chlorine solution using one gallon of water and one-half cup of chlorine bleach (5% so-
dium-hypochlorite solution). Prepare enough of the chlorine solution to administer one gallon of solu-
tion for every 15 gallons of tank capacity. For sanitizing this unit, prepare 4½ gallons of the chlorine
solution. This mixture puts a 50 ppm (parts per million) residual chlorine concentration in the water
system that will act as a quick-kill dosage for harmful bacteria, viruses, and slime-forming organisms.
Concentrations greater than 50 ppm may damage the water lines and/or the tank.
3. Once the freshwater tank is empty, close the drain valves in the water tank.
