Good tip. Thanks.
We live in the country and our well water (although very safe and very good to drink) has a lot of minerals in it and also a lot of rust. (rust is good ... it's iron!) But it does leave things very hard to clean and stains over time.
We eventually had installed a Kenetico Whole House filtration system. I suppose its kind of like Culligan. Our's uses 2 sand charcoal filtration tanks and also a tank for salt for water softening.
It works great! It removes almost all the hard water, all the staining, and reduced all that hard cleaning to almost zip!
However, the outside spigot on the house was still plumbed prior to the filtration system. When filling water from the house to the fresh water tank, I was running a garden hose all the way to the laundry room where I put a quick disconnect on and could run the hose to the camper.
Also washing the trailer and the vehicles was a pain, leaving spots.
After several years of fighting the outside spigot, this last spring, I took the plunge, crawled under the house and ran a second spigot outside with the filtered water. So now, outside the house we have 2 spigots beside each other. One is the filtered water and the other is not!
The filtered water took care of all our problems. The water in the camper is nice now. Washing the vehicles is a breeze, and life is so much nicer now.
I suggest, rather than finding a band-aid for the broken arm, get the arm set and get it fixed right! Consider a whole house filtration system. They are not cheap, but they are worth every penny once you have one!
FYI, Kenetico takes no electricity. It backwashes itself, and it only does that when the water is used, unlike the electronically controlled ones that automatically backwash and filter themselves clean on a daily or weekly or monthly basis if water is used or not.
But, thanks for the tip too. I may try it, and combined with already conditioned water, I imagine washing anything then will turn out marvelous.
FYI! Really nice looking camper you have there!
