City/well water inflow blockage

[janelf]

Trying to get ‘city water’ hooked up in ‘06 23’ safari.
First time since purchase. Hooked up hoses for ‘water in’ and grey water out. No water exiting except stream outa LAV sink. Rest exited at BACK end of AS UNDER DRAIN VALVES. Then shut off drain valves - tried again- same. Turned lav sink faucet off and water flooded floor of AS! 😩 back to drawing board.? This AS hasn’t had plumbing working in as much as 3 yrs or longer ? Feels like clog somewhere. We are newbies to RV’s! 😜🤪
Any ideas❓

Hi

There are three places to hook "water in" on a typical AS trailer ( maybe more on some ... who knows ....)

1) The fresh water tank fill, often behind a little locking door. Usually without a threaded hookup.

2) The black water flush input. Looks like a very normal hose fitting. It's used to flush the black water tank after use. If left on, can create all sorts of exciting flooding.

3) The city water input. This is the normal place to get water into the trailer when camped with full hookups.

First step after pulling any AS out of winter storage is to check for damage. Turn off all of the faucets and drain valves. Feed in city water. Make sure there are no leaks. If there are, repair the damage.

After that open up the hot water heater ( undo the shutoff process ) and make sure that does not leak.

Go over to the low point drains and open them one at a time. Let each of them blast on the ground for a bit until you have no air bursts and no obvious anti-freeze blowing out. Close each one after it's been "purged" ( = only one open at a time ).

Next move to the inside of the trailer. Open the cold faucet on a fitting and let it blast for 10 minutes or so. Close the cold and repeat with the hot. Step and repeat for each faucet. ( While checking the tank levels or while hooked to a drain). Once you do all the faucets (including the outdoor and indoor showers) do the toilet.

We go through this process about three or four times before going over to long term flush mode. That involves one or another faucet running for a few hours.

Now pull the city water and fill the fresh water tank. Try all of the same stuff while running the water pump. ( each faucet, not the hours of run time).

At this point you should have the air out of the lines...... except that some hot water heaters have a vent on them. Check your manual.

Past this point, it's mainly a matter of how many days to flush to get the anti-freeze taste to a tolerable level. Once that's done, put some bleach solution (lots of water and not much bleach) in the fresh water tank. Run it through everything. Then flush it all out with fresh water.

Fun !!!
