Water issues - Thor Quantum 31
We are first-time RV owners - 2017 Thor Quantum PD31. Before taking it for our first shakedown camp experience, we decided to dry-run the various systems at our home. Several items surfaced, but three in particular that are all water-related. I have read the manuals, but find nothing of help. We are scheduled to leave Wednesday on the shakedown cruise - just want to make certain we do not cause any damage.
First issue: city water supply system. We sanitized the potable tank and system per directions, and it went smoothly. With the potable tank full (40 gals), I connected a hose to the city water supply (located on driver side of the rig), and soon noticed water dripping on the opposite sidewall (passenger side) near the potable fill port. I saw no leaks under the rig, but when I unscrewed the potable fill cap, water gushed back out as though the tank were terribly overfilled. An RV friend said that is not normal - there should be an overflow to drain excess under the rig. And, regardless, why should the potable tank overfill when the city supply is connected?
Second issue: I attached a hose to the water intake port inside the black/gray tank area, to add water and practice flushing the black tank - first time doing this, so wanted to practice (tank had never been used). As water was filling the black tank, I noticed water dripping on the opposite wide of the rig .... water actually found its way into a lower storage compartment not far from the potable water fill port. After detaching the hose, the leaking stopped.
Third issue: We turned on the icemaker and ran for 24 hours - we have the residential unit that runs on 110 or generator. Temps were good. We then turned on the icemaker, but even after 12 hours, there was no water in the ice cube filler bowl to make ice.
Not knowing much about these things, I wonder if they could be connected in some way, or if I am simply ignorant of how to do these functions properly.
I sent an email to the service manager at the RV dealership where we bought the rig - today is Sunday, so no one is on the phones. Hope to hear from him quickly as we already have reservations for Wed and Thu night and would like to have probems resolved.
Thank you, forum, for whatever insight you can share.
