CITY WATER HOOKUP
Use a high-pressure hose of at least ½ “ diameter. It should be a tasteless, odorless
and non- toxic hose designed for RV use. The city water inlet is a standard garden
hose thread. We suggest you carry two lengths of hose.
This way you have the ability to reach hookups further away than normal, plus you
have a spare hose should one fail or become damaged unexpectedly. Be sure to turn
the water heater bypass to the normal flow position as described under the Water
System Self-Contained part of this section so it will fill.
After hooking up the hose and turning on the city water valve provided in the park,
slowly open a faucet. There will be a lot of spurts and sputtering until all the air is
expelled from the motorhome system. If the water heater is empty it will take some
time before all the air is expelled and you get a steady flow of water at the faucet. Once
a steady flow is achieved at one faucet, the others should be opened long enough to
expel the air in the lines going to them.
CAUTION : The Sureflo water pump should be turned off when hooked to city
water.
Your plumbing system has a built in pressure regulator to protect your lines and faucets
from extremely high pressures on some city water systems. An after-market external
regulator is not recommended, as it could lower the water pressure at the inlet and
thus to your faucets and shower.
Exterior Shower
An exterior shower is provided for your convenience. Be sure to drain the hose and
open the valves before opening the low point drain lines for winterization.
