All went well for the two nights we stayed there and the low temp was about 37. When we left this morning at our first rest stop, water was pouring from the low point hose. When we arrived at our destination I hooked up the water and everything appeared normal. When I looked two hours later, it was pouring out again. Any suggestions or do I go to the repair shop? Thanks in advance.
On our 2018 Road Warrior, sister unit to the Cyclone, I have 2 low point drains. One is red for hot water, the other is blue for the cold water. There is another "low point drain" which is a drain for the fresh water tank. So which drain is it coming out of? There is also an overflow line coming from the fresh water tank above the axles on the driver side.
Check and see what position the Anderson valve is on, make sure it is on city, not on fill. There is a possibility the Anderson valve is damaged and needs to be replaced.
The inside of the Anderson valve on these is made from plastic and there have been numerous cases where there is a leak by and the fresh water tank is being filled and will overflow. The new Anderson valve replacement is made from brass inside parts.
You may be able to get it to work by turn the water off, release the pressure and then rotate the handle 4-5 times to see if it will get the Anderson valve to reset itself. Sometimes it works and sometimes it does not.
The yeti pack is for the water line from the fresh water tank to the water pump. The big switch plate with the red switch is for the tank heaters for the holding tanks.
Hope some of this helps.
