Water Heater
Your motorhome will be equipped with one of these three
types of water heaters:
• Tank-type (6 and 10 gallon)
• Tank-less (on-demand)
• Hydronic (on-demand)
For complete safety information and operational instruc-
tions on the particular water heater installed in your
motorhome, please refer to the water heater manufactur-
er’s guide contained in your Owner’s Packet or visit the
water heater manufacturer’s website. For information con-
cerning your particular motorhome’s installed equipment,
contact TMC Customer Care or refer to the TMC Water
System Guide, available from the TMC website.
Sanitizing the Fresh Water System
Sanitize the fresh water system before initial (first time)
use, after extended periods of motorhome storage, at least
once a year during continuous use, or if the fresh water
system, fresh water supply, or fresh water holding tank has
been compromised or contaminated.
1. Remove or by-pass the potable (drinking) water filter
(if equipped).
2. Disconnect and cap (or by-pass) the refrigerator ice
maker inlet water line (if equipped).
3. Disconnect and cap (or by-pass) the dishwasher inlet
line (if equipped).
4. Disconnect and cap (or by-pass) the washer inlet line
(if equipped).
5. If equipped with a dishwasher, ice maker, or washer,
follow the appropriate appliance manufacturer’s
instructions pertaining to sanitization.
6. Prepare a solution using a gallon of water and ¼ cup
of liquid household bleach (5% sodium hypo-chlorinate
solution). Use one gallon of solution for each 15 gallons
of tank capacity.
7. Open your fresh water tank bypass tube shut off valves,
or uncap them.
8. With an empty tank and all faucets and drains closed,
pump the solution into the fresh water tank, via the
water fill cap using the water pump. Or, carefully pour
1/4 cup of bleach for every 15 gallons of holding tank
capacity into your potable (drinking) water hose before
connecting it to the water source. The water source
pressure will push the chlorine and water into the fresh
water tank, making the correct dilution when the fresh
water tank is full.
9. Completely fill the fresh water tank with fresh water.
10. Switch ON the water pump. Open all the faucets one at
a time until all air is purged, and the water flows freely.
11. Add fresh water to the fresh water tank again, until the
water level reaches the fill spout.
12. Allow the solution to stand in the fresh water tank for
at least three (3) hours.
13. Drain the fresh water system by opening all faucets
and the fresh water tank drain valve while flushing the
system with fresh potable (drinking) water.
14. Continue flushing the system, allowing the water to
flow for several minutes.
15. Close the fresh water tank drain valve and the faucets.
Refill the system with potable (drinking) water.
