Yes - I thought the same about restriction. I have checked my hoses for kinks. (multiple times) I verified my regulator is at 50-55 and ran the water/hose directly from spigot without the regulator and/or external filter. Then, I read the manual to look for anything internal 'filter' related as well as the entire plumbing section, but found nothing.
I did notice the pressure does drop when we are washing dishes or other (always has) so I will I'm going to take notes for numbers today. I also think I'm going to remove the pressure regulator when I get the gauge to test actual spigot pressure from Amazon.
I do have one of those back flow valves on the coach, down in wet bay, where the city line goes.....that is new, having just been installed in Jan/Feb (old one was leaking) I guess it could still be that, so I can check,(Can return if not)
im trying to do one thing at a time in the process of eliminating and I refuse to let it win 🤣
I just know it's something I'm going to find and kick myself for as a newbie learning. Although, I do love learning, soooo I love the challenge. Ha!
appreciate the many suggestions.
I have one (in the mania) only for use with using water pump (so it says) then, there is one bypassed only for the ice machine, (there are shut off valves) because we don't use it. I'm going to triple check and take a photo hoping some of you well seasoned campers can set me straight.
