-Does everyone use a water filter when hooked up to city water?
-Does everyone have a surge protector and what kind? Seems Progressive Industries has a nice surge system but is about $250, is something else better? Do you have a lock for it?
-Do you use a water regulator and what pressure should I aim for?
-My trailer has 2 dumps. Do most of you just switch the sewer back and forth or do you Y them together?
1. Cheap, like $20, so why not. Not all city water tastes great. (Our city had e.coli over Christmas! Yeah!)
2. I have one, kind of a luxury and can be added at any time.
3. Yes, required. Get an RV one and they are already set at something like 52 pounds (I may be wrong on that number but you don't adjust them).
4. Switch would be my vote.
