Up until 2008 I NEVER turned water off......always used 'city water' connection when available and water pump was for 'dry camping'
Then one morning ---4:30am to be exact----dog woke us up acting strange.
We had a 2' wading pool in living room/kitchen and our site plus 2 others were flooded.
Cheap $0.50 fitting at water heater Hot out and broken and 'city water' ran for several hours.
Ruined our day plans .....Devils Tower CG
We squeegeed, we broomed, we used a shop vac (16 gal---dumped it 12 times), we ended up pulling carpet up (put it truck bed for Ins. Adjuster) and run fans/blowers all day long.
Packed up and left next day for Casper WY..
Repairs over 2 weeks, 3 days in Hotel etc.......$6000 Plus
YES we turn off the water.....city water is for filling fresh water tank.
Fresh water tank IS the source for water and PUMP gets turned OFF at night, when we step outside, we when leave etc.
YES.....I am now a TRUE believer. Simple flip of switch and NO WORRIES.
That fresh water tank and pump are NOT just for dry camping
