PLUMBING
The diesel burner is the primary heat source with at
least 50,000 btu (more on select Oasis models), and the
electric elements are secondary. Depending on your hot
water usage, using only the electric elements may be
sufficient; however, if not, use the diesel burner when
not plugged into shore power or in conjunction with the
electric elements.

Domestic Hot Water via Hydronic Heating
This article provides a basic overview of domestic hot water via the Oasis hydronic heating system.
The hot water in your coach is
heated by the Oasis hydronic
heating system. To operate
an appliance that uses hot
water, or to assure plenty of hot
water for showering, turn on
the boiler or heating elements
using the Oasis control panel
or the SilverLeaf touchscreen (if
equipped) located in the front
overhead cabinet.
Both heat sources (diesel burner
and heating elements) can be used at the same time
for the maximum water heating capability. Turning only
the 120 volt heating element(s) on will usually provide
sufficient hot water for most household chores, but may
not be sufficient for showering.
Water Heater 2-Valve Bypass System Overview
This article provides a brief overview of a Water Heater 2-Valve Bypass System. The 2-valve bypass system is located near
the water heater.
Using the bypass valve(s) while winterizing your coach
will prevent anti-freeze from reaching the water heater.
Draining the water heater during winterizing is required.
On some coaches, this consists of two valves: one at the
inlet and one at the outlet of the water heater.
By closing the inlet and outlet valves, it opens the bypass
hose between the inlet and outlet lines allowing the
hot water lines to be blown out and RV winterization
antifreeze to flow through, bypassing the water heater.
Operation
1. Fill or partially fill the fresh water supply tank.
2. Open the kitchen and bathroom faucets.
3. Turn the water pump switch on, and allow the water to
fill the water line and the hot water heater. The switch
to this pump may be located in the exterior water
compartment, in the kitchen, or in the bathroom.
4. Close each faucet after it delivers a steady stream of
water (close the cold water first). Leave the hot water
faucets on until they also deliver a steady stream of
water. This will ensure that the water heater is filled
with water.
Water Pump Operation and Basic Troubleshooting
The water pump is self-priming and totally automatic, operating on demand whenever water is required. When not
connected to city water, the coach’s water pump is used to pump and pressurize water from the fresh tank for distribution
through the hot and cold water lines.
Water Pumps and Controllers
When the water pump switch is turned on, the water
pump builds pressure in the system and will shut off
as soon as the system is correctly pressurized. When a
faucet is opened, the pump will turn on and operate as
necessary to maintain the preset pressure in the system.
Water pump operation is not necessary while the coach is
connected to city water, since the potable water is already
pressurized.
When using water at a low flow rate (GPM), the pump may
pressurize the system and short cycle, meaning the pump
shuts on and off quickly. In many cases, the pump will
stop short cycling if the flow rate of the water is increased.
