OK, here is a timeline.. all you X purts out there put your heads together and point me in the right direction..
I have a huge problem with water backing into my shower after about a gallon of water goes into the gray tank. It was a little at fist, but now it is impossible.
Here is what we all tried to do at the mtn. Ranch rally
to get me up and running again... none of it worked.
The thing acts like the Grey tank is full, but we all know its empty. You can hardly get anything in it.. from the drains..the first thought was the vent was clogged so....
We jambed a hose down the vent and tried to rotor rooter from the top. No clog. So, on goes the water and we try to blow out from the top. The grey tank filled and eventually, as you would expect, the drains spit water up in all the sinks and showers.
Hmnn... drain the tank, which is now REALLY full, try again from a faucet.. a gallon or so goes in, and water comes up the shower.
So, we drain again, and get the trickle you would expect.. everyone them jumped in the trailer and we all "manned" a drain, keeping it plugged while water went down one of the kitchen sinks. We actually got the tank to fill again that way, and managed to get water to come out of the vent.. but... no small animals, old Kleenex or anything else unsavory come out. (At one point, a couple sticks that looked like knitting needles jumped out of the kitchen sink.. probably someones miniature Kabob gone astray...)
So, Try running water as normal again, and sure enough, the shower fills up in no time. ARRRGGHHH!!!
Next, we try back flushing.. everyone on a drain, Linda holding the broken dump cover on while the hose is filling from the DRAIN side. Once again, we get is pressurized enough to get water to come out the vent.. but still, nothing unsavory dislodges.
In between these games of drain twister, the tank sat overnite with Baking soda in it, and we dumped a bottle of orange cleaner, and Dawn dish washing soap in, thinking it was grease that had filled the tank and it had no capacity left.
Since it can be filled from everywhere else but a drain INSIDE the trailer, that seems unlikely. We got gallons and gallons to come out after we filled from backflushing or from the vent.
None of this has done anything but spring a new leak UNDER me sink, which I have not found the source of yet. I am pretty sure it's a loose city connection.. but we will see.
After everyone left, I messed around with changing the level of the trailer.. that did nothing either.
I give up.. where now?
