Before I put in my new anti-siphon valve I unscrewed the in line at the tank fill shutoff valve and then hooked up a hose and "back flushed" the line. I capped the outlet end with an old sock (no holes) with a rubber band and banged on the water line wherever I could all the way back while the hose was running. Absolutely amazing how many mineral deposits pieces came out!!

Now check the screens on your faucets, seeing as how you have been disturbing the water lines.

During some plumbing work on our new to us coach we found mineral deposits in the faucets and hose fittings. We removed our water filters, (we have two, the Pentair under sink and a whole coach one we just installed during wetbay remodel. Then did a flush of the H2O system with a vinegar/water solution.  Introduced the diluted vinegar by siphoning it into the fresh water tank. Left it overnight. Got a fair amount of milky liquid out of the Atwood heater and all the faucets. Afterwards when checking faucet screens they were clean. Unfortunately this system flush procedure doesn't reach the check valve which is located upstream of the fresh tank. Next year want to set up a container with some vinegar on the upstream shore water supply side so the solution can be drawn thru check valve into the tank while filling.

Not sure why but the propane detector went off during the vinegar solution flush. Had that momentary feeling of "what now!" Soon realized that because the propane gas was off the alarm might be related to the vinegar odor. Alarm quit once we opened windows and turned on the fans.

What do others do to keep mineral buildup down?

I had thought it would be a big can of worms to get at the ASV from the wet bay where the water hooks up. The more I looked at it (on my trusty stool), it made me open the compartment to the left front. Pulled the enclosure (the one with the 110 v. outlet) and there it was!  ^.^d
P.S.: I have NO IDEA what the little black plug do-dad is under the outlet.

Some of us carry lighters!  What did you REALLY use it for? I think you'ce got a couple of those under the passenger-side dash, also.

We have real hard water down in Arizona. Hated taking showers and worried about build-up in the system, also. Got this unit (Amazon) and love it. I flushed the entire system and have checked a couple of times, clean, clean. There is a smaller model than ours available which would be easier to move around (they are HEAVY!), but since we pretty much stay in just a couple of Parks, it works well, since it does not have to be regenerated as often, we do ours once a month. Buying a water tester is a good idea, tells you how much salt to add, depending on use. Be glad to help, the REP in Phoenix has been very helpfull with some of my bonehead questions. ^.^d

I plugged in a spare potable water pump mounted on a board to be able to fill from CG spigots with no hose connection threads.

Recommendation I found was fill water heater with 5% vinegar and then turn on water heater for 4-8 hours in order to bake off any deposits. Works great!
I also filled lines with 5% and let set for 3-4 days, then ran fresh water thru lines in order to get solution in grey water tank for next dump.
By the way, 5% vinegar will kill your grass if you dump it on the lawn, even accidentally. (Not guessing here. Actual dumbass mistake)

All good advice. I happened to talk with a RV tech that was working next door just now. He said "I make a ton of money off owners that do not have proper filtering equipment." He liked my water softener!  ^.^d
