I don't think when your hooked up to city water you should "pull" or get any taste from the tank. But, if the unit was winterized before you bought it and you didn't flush/ sanitize the water lines you might have some pink antifreeze reside in them that would make the water taste funny for awhile until it all gets flushed out of there. How would you describe the taste?

My furnance was squeeling like the blower was bad. Turns out it was the exhaust stack outside screeching due to vibration. I took out the exhaust, cleaned it up real good and no more noise.

I just replaced the front fan motor for the screeching noise,there are no bearing in the motor. $79.00
You need dc volts to run the fan motors I have solar that charges my batteries to ~13 volts before bed, about 7 amps per motor pulls some power from the batteries. On my Discovery the shore power only charges battery ,but no power goes straight to any dc in the coach.
NEVER run the pump with park/home water, it blows the top of the pump,don't ask how I know,after reading the instruction with my new pump a light suddenly came on.
The inverter will hum when charging. I have a TriMetric 2520 that show amps and volt usage and can see volts drop and amp rate when fans/lights are on ,and if charger is off volts drop and amps rise with fan/light use with shore power.

You want to use a psi water reg anytime your hooked to city water and never go over your 40 psi rating . .reason being is most plastic lines are rated for well over 100 psi but alot of connections (joints,quest joints) are only rated for 40 psi

Re your surge guard, had a 5th wheel that had a 50 amp SG. It said it was okay to use it for 30 amps, but not on a permanent or regular basis. Sorry, do not recall the name.

Typically, if it screeches, replace it.

My inverter hums but is only audible outside with cargo hatch open.

And lastly, what the hell were you thinkin' trying to use your RV .... they are only for waxing !! (yours looks awesome !!).

That's what I was thinking, for $80 it's worth the peace of mind.

My wife was starting to think these things were only for waxing AND tinkering!

I also had the screeching heater blower fan upon first startup of my Atwood--it just got worse. Replaced the blower motor--not too easy, but not too hard either--took about 2 hours. You can find the part on-line around $75. Then you won't have to worry about it again for several years.
You may need to check your Freedom inverter min. charge setting that is programmable via the remote panel. It will hum loud at max charge rate when first charging, but should taper off and go down to a very low hum as batteries approach full charge (Min. charge setting). I have mine set to 10 Amps. Check your remote panel manual to set the inverter's settings. This is also where you set the inverter for the type of batteries you have--also important. My internal inverter fan cycles on and off but normally does not come on unless I am in the "INVERT" mode. Rarely comes on while charging unless it is a hot day. Hope this helps.

The inverter/charger in our Providence is mounted in the electrical bay, which is also near our rear bed. We've never heard it inside the coach.
