  • Need to relieve pressure in system before moving valves on new Nautilus panel?

    I've done searches and haven't found anything on this topic. Our experience with the old Anderson Brass fresh water valve on our Reflection taught us (the hard way) that, unless you depressurize the fresh water system before rotating the valve, you are at high risk for loosing an O-ring and rendering the valve useless. It's also best to always rotate the valve slowing clockwise and the valve needs to be lubed at least once a year with a good silicone plumbing lubricant. None of this was in the Anderson manual nor the manual that came with the Reflection - of course.

    I don't know how the innards of the valves on the Nautilus panel are designed or put together. From this knowledge vacuum and innate paranoia comes my question: is it necessary to depressurize the system before changing the valves on the Nautilus panel - i.e. when changing from city water to dry camping or vice versa?

    I have exercised this since new , relieve pressure then change valve position. I am not sure if it is needed but that is what I do. Last year we were at a campground that lost power. We were hooked to city water with water in the fresh tank. I did relieve pressure before switching to pump pressure. I have removed the valves on a Nautilus panel to see what they are , I have a spare panel here. They are plastic molded with all parts inside the plastic. I do not see a way to service these valves or for a way to lose an o-ring but not saying that it can not happen. The Nautilus panel is nice but I think a 1 or 2 valve setup would be just as good.

      I'm with Brian--I always relieve pressure before changing a valve setting. Probably because of all the info I read on the Kantleak when I was new to all of this.

      I've never done any nor do am I aware of any preventative maintenance recommended for the panel.

        Some people have had issues with the valves on the Nautilus panel and I have read it suggested the best way to get good life out of them is to relieve the pressure otherwise they start to leak and cannot be serviced.

          Thanks, everyone - I'll keep doing what I've been doing, then.

            This message on the front of the Nautilus panel always freaked me out. I never understood what it meant but I always relieved the pressure on the system before moving any levers on the panel

              That just applies to the check valve on the city water inlet - another place in which you should not stick your finger...

                My manual says to turn off city water before turning the valve to fresh water fill. That doesn't really relieve the full pressure but I imagine it does reduce the pressure.

                I have a small valve between the hose and the Nautilus panel. I put that there so I could easily turn off city water if I ever wasn't in the TT. That way if something starts to leak when I'm gone only a finite amount of water will leak.

                I have used that valve the few times I've switched from city to fresh fill. Haven't had my TT long enough to know if that valve is good enough not to blow an o-ring out I'm going with it for now.

                  I've read numerous inputs that it's advisable to release pressure first, so that's my practice and so far no issues. I'd rather be safe than sorry.
