See attached photos for two little modules coming off of the side of my 6 pack.  One of them is leaking.  White arrow drawn to the leaking one.  The electrical connectors were disconnected by Newell at some point in the past.

very common place to leak and most just take them out and plug the hole. they are pressure sensors. there are at least one on the front six pack as well.

you can read on the label of the sensor if it is a low pressure or high pressure sensor.

i have replaced the ones that leak on mine but had to order them and it took months to get.

if you ask newell, they will tell you to disconnect them and plug the hole if they leak

Thanks Tom. Perfect!

I am typing on a soda cracker, so please overlook typos. This is my understanding of how and why the sensors interact with the hwh system. The ones on the front sixpack prevent the front airbags from dropping below a preset pressure when leveling the coach. The idea being to prevent an excessive twist n the frame that would result from one of the bags ffrom going solid. Or the prevet twist which would hinder slide in and out. The rear switch does something similar, but only measures pressure to give you an alarm if the pressure is too low to travel. All of the switches are normally closed, meaning when the desired pressure is reached the circuit opens. The is why disconnecting the switch tricks the hwh brain into to thinking the necessary conditions for travel or slide movement are satisfied. I have used the coach with all of them disconnected and i have gone to the trouble of sourcing, replacing, and connecting the switches. I dont know that i can tell much difference. If you order front switches be aware of the pressure setting. I have read reference in hwh literature that different manufacturers used different pressure set points. I do not remember what the setpointsmare for our rigs

Problem solved with an 1/8” NPT pipe plug.
