HELP! No Water!

We are new owners of an 87 Winnebago Chieftan 31'
Previous owner winterized and we can not get our water to work without being hooked up to hose... After 4 stressful hours last night we are no where :-( I feel like we are missing a valve somewhere that is open? but I can not find a plumbing diagram? The water pump looks newer and is under the stove drawer. We just can't figure out what we are doing wrong? Is there possibly a valve we are not closing? Help our county fair is next week and we have 4 children... we need a potty!! lol

Can you hear the pump kick on when it's turned on?

Are you sure you have fresh water in the tank?

I can't help but if you post what you've already done, others may be able to give you better advise.

Good luck!

If he winterized it there is also a hot water tank bypass to worry about. Figure that out before you turn on the water heater.

I do not know your unit. What I have seen is either a panel with several valves so you need to figure out the pattern or a shut off valve between the pump and water tank so one can shut off the water tank before filling the piping and pump with anti freeze. Those also have a T fitting with one leg capped to add the anti freeze through. Pictures of what you have will get you better help.

It may be that the line from the tank to the pump was disconnected to feed antifreeze to the rest of the RV and it has not been hooked back up.

After you remove hose, close that valve.

Ok, al lot of this is "Generic" but...
The most basic water systems (COLD ONLY, I will do hot later)

Note.. This is not how it is done.. but is effectively how it is done

City water enters via a check valve (part of the inlet) and then goes to one side of a "T" fitting (Reality check, feeds into the water system at the closest point)

Tanked water goes to the pump, which contains a pair of check valves and feeds the other side of the above T fitting (Reality check, same as above)

The water system comes off the "T"

Possible issues
No power to pump
Pump inlet strainer open to air
Tank outlet valve closed
No water in tank

SOME RV's have a "Winterize" line and valve.. This is used to such Pink stuff out of the bottle into the lins for those who choose to waste money and put noxius stuff in their water lines that is hard to rinse out come spring... (I did it once.. after that I used the dry method.. If air freezes I'm not going to worry about the RV's plumbing).

IF yours has this valve it becomes #1 on the suspect list.

Hot water....
Hot water has a bypass system This may be 1, 2 or 3 valves.
1 Vlave has a check valve on the water heater outlet
To bypass put valve in bypass postiion (Usualy pointing toward the watr heater outlet or the bypass label)
To use return to the use position Pointing toward the cold water inlet

2vlaves one on the hot and one on the cold
Bypass they point toward each other
Use toward the tank or 180 degrees from the tank

3 Valve One in cold line, one in hot, one connecting the two

Bypass close hot and cold valves, open bypass
USE.. Open hot and cold, close bypass

Do not forget the water heater drain plug.

Home is where I park it!
