Doing a fresh water system sanitizing on our new to us MH.
I drained the fresh tank, filled it 3/4 full, added 5oz of bleach then ran it thru all the lines. The next day i would drain the tank, do a couple of fresh water flushes to get the remaining bleach out. I fill the tank with fresh water and proceed to turn on shower, kitchen and bath sink. As i go out to the wet bay water is pouring from in back of the panel.
I actuall thought i broke a line or did something. Had to leave due to an appointment and much thinking of what to do next. Next day i go back no water dripping... thats good, turn on the pump still all good. I go inside and turn on one faucet at a time and very soon the water is leaking again.
Not as bad as before but still leaking. Now i'm taking off whatever i can to see where its comping from. Nothing wet under kitchen sink, bath sink or shower. Still hasn't dawned on me that the grey tank is overflowing at its top and running down everwhere.
Our last coach when the grey got full and we didn't realize it the shower tub wolud start to fill. I go out to the wet bay where it's leaking from remover 4 screws to lower a 4' long cover holding outlets, coax connection, outside shower, etc. etc.. Now I can see water flowing from the top down the tank side and on to the cover.
All of a sudden i think to open the grey dump and within a minute the flow stops and i fell much relieved. Didn't even want to think about fixing a line burried behind, under and over places i couldn't get to.
Put everything back as it was, didn't do any damage to anything and learned something new about our rig.
Thinking more about this it is a safer design to overflow outside but why an overflow tube of some sort rather it run over outlets, coax connections etc. in the wet bay.
