Check your HWH leveler reservoir

So waited till my HWH leveler malfunctioned to check its fluid level.  MISTAKE, it was over a quart low.  Not easy to check, mine is inboards the generator and propane tank but has a full indicator pin hole on the fill/breather cap.  A mirror and small funnel helped.  I used the OK to use Dexron transmission fluid.  The Napa guy said he sells a lot for this.  If just peek under and if the tank is dirty with oily grime the cap could be loose like mine and losing fluid.  Should also check just to get familiar where the manual retract valve levers are just in case.

Thank you for posting this. I will check my cap today. I clean the reservoir frequently which seems like it is leeching fluid and collects dirt. The level is still in the ok zone but now I am wondering about the cap which I have never checked.

When you say "inboard" what do you mean?  What does it look like?

Just returned from a trip and is the first time we had a problem with one leveler not coming down unless manually assisted. It was on the "to do" list as we clean to winterize.

Toward the center of the undercarriage inside a frame rail.  Looks like a small plastic tank with a pump and 4 cylindrical valves attached at front.
