Fresh water tank leak?

Hello, my plans for this long weekend Canadian Holiday appear to be over. Perhaps some one can help. Got a 1992 winni Adventurer 34ft diesel from a relative in ca in Oct, winterized and stored. Last week in prep for the first time ever out in this rig and found the headliner to be sagging every where. Shops here said they do many every year and many much never because of poor glue, cold winters etc. ($3000 est) I used screws for a temp fix.
I drained the water and pink antifreeze mix, closed all taps etc and filled with water from a garden hose. My drive is at quite a sever angle, the 100 gal tank was soon full and water coming out the fill tube. Turned the pump on and all seemed to work ok for a while. The green lights said the tank was full and after and hour it was empty and water contined to flow from the steel pan under the tank. Hot water was full as I tested the pressure valve and go a big blast of water. Today --nothing as it appears to be empty. The bypass is in the normal position. Direct City water will only provide cold from bath room and not kitchen. I winterized correctly so I don't see how I could have a burst -whatever. Some one must have a suggestion before I go back to the dealer here that costs $140 per hour. (not a mistake-Woodys Rv St.Albert Alberta Can).

Next problem- installed two coach batteries to replace the dead ones. They read from 12.8 to 13 volts. When I unplug shore power the 12 volt lights don't work! Also the Onan Generator just clicks away and won't turn over which to me sound like a low battery or starter issue. I am totally frustrated by all of this and I know lots of $$$ will solve some issues for a time. I've only had modest travel trailers in the past and this motor home is looking to be a huge money pit before I get to use it.

The good news is the furnace works, and the cummins starts and runs well. Interior and exterior also look good.

Thanks in advance to anyone that responds.

Ron

First thing to check is the valve positions around the tank and fresh water fill. The tank has a drain as well as low point drains in the hot and cold piping.

As for the 12VDC system, when plugged in, what voltage do you get the batteries? Should read about 13.8 volts with fresh and charged batteries. It sounds like your batteries may be disconnected by a disconnect switch.

Ron;

I believe Ken has given you good advice. I believe you have a battery disconnect switch somewhere. I had a 97 Adventure and if I remember correctly it was located by the entry door post. I believe the reason your generator clicks and the lights don't work is because you are not drawing power from the batteries and only from your converter.

I also agree with Ken on your water issue. If you are losing water with the water pump shut off you probably have a drain valve open some where or a leak between the tank and pump. If your water only disappears when the pump is on that you likely have a leak in the pressurized system some place.

On your kitchen water issue check for a shut off valve under the sink and if there isn't one check for a plugged screen in the faucet.

Ken, there is only one shutoff/drain valve under the fw tank. Only other item is the hw bypass. Nothing else to open or shut. We are going out over nite anyway to see what lse may be a problem.

The 2 coach batteries are close to 13 volts. When i unplug 110, the coach 12 volt woll not work so something is very wrong. There appears to be only one way to wire, pos to pos, neg to neg just like it was wired when i removed. I don't know if the 12 volt on battery ever worked because they were dead when i picked up the RV.

I tried hooking up battery charger to the red pos cable on the generator and when i push the manual start there is NO clicking. When I try with the just the coach batteries at least it clicks which is ususally caused by low battery or bad starter.

Goes in on Thursday if I can not find and fix. Thanks for the reply.

It was close to 90f on Tuesday, it is just above freezing this am. Thats Alberta!

There will be a fresh water drain somewhere. Winnebago always installs one.
Mine in in the service bay. On my last Winnebago it was near the pump.

Thank you for that, I have the 1992 diagrams but I don't know that they are much help to me. The slope of my drive must cause the overflow to siphen the water out. Filled the fw tank at the camp ground and it did not leak. The pump works but only cold to the bathroom. Same for city water supply. The results are the same with the hot water tank on normal or bypass.

The auxillary battery switch was "off" that's why I didn't have 12 volt earlier. I got the gen set started, two overload switches were tripped so I re-set. I can only start from the gernerator starter an not from the remote on the fan hood or the bedroom. All the fuses are good. Any suggestions?

I know I need a course on MH operation and maintenance.

You were right about the battery disconnect. The switch does say AUX on/Off. I need to read more. Thank you

Ronkoro,

The hot water issue sounds like the infamous hot water heater check valve issue. You might see any of the numerous posts on this forum for the solution to that.

The generator start issue sounds like corrosion in a connector. Onan uses a grounding circuit to operate the remote start. In other words, depressing the switch creates a grounded condition in the circuit.
