Typical Hot Water Heater
Your vessel may feature a hot water heater option. It
mixes cold water with recirculating engine hot water with
a tempering valve to safety keep the temperature below
130 degrees. The valve incorporates an adjustment valve
which can be turned to adjust the water temperature as hot
water mixes with cold water running through the system..
There is a one-way valve that keeps the hot water from
back ushing into the cold water supply. The hot water
heater is located in the engine room.
A 15 amp breaker at the main ship’s AC panel controls the
water heater circuit. Always test the water for temperature
before amercing body parts in it. See auxiliary system
chapter for more information.
Typical Shower Sump Pump System
Your boat features a head with a shower usually located
under the cabin entry stairway. As part of the drainage
system a self-contained shower sump pump collects all
water and debris. After the water reaches a predetermined
level the oat switch permits the pump to send the used
shower water to an overboard thru-hull tting or into a
tank depending on the systems onboard.
After showering, always let about one gallon of water
settle through the shower drain to help rid the shower,
drain, lines, and shower sump pump of possible debris,
hair, and mineral deposits.
