Gray water tank #1 empties slowly?

[lakeside013104]

My gray water tank #1(shower only) takes about one hour to empty out from first pulling lever, which releases a full pipe gush of water for 10 seconds, down to a slow trickle of water that takes one hour to completely stop running. (The water supply valve and water pump switch are in the off position so no source of water is going into any of the tanks).

The gray #1 lever pulls out the same distance, about 4 to 5 inches, as gray #2 and the black water levers. The pull out resistance is the same on all three levers. If it matters with answering my question, the tank level indicators inside the 5er read as follows: black=empty, gray #2=empty, gray #1= 1/3.

My 5er is a new 2014 model with about 40 nights of use and about 10 tank empties. Could my gray tank #1 have an obstruction, possibly the cutout, or is there an adjustment on the tank valve lever that is not allowing it to open fully?

Any ideas to assist with this slow drain problem would be appreciated. Gracious.

Correct Grady23, Fish Tape, just a typo. A FIST tape could get a little messy. 🙂

I had that problem and it was the 3ins slug left in the tank when the drilled the hole for the gate valve.

I had the same problem. Went to Home Depot and bought a new vacuum breaker. No more problem. Good luck.

Thank you folks for the ideas. I will try them out and write when I have eliminated the problem.

You would think that a unit having a retail price of $85,000+ ought to have some really good workers that take pride in their finished product? Leaving construction debris inside the tanks shows me some of the employees have "don't give a crap" attitude. I expected more from Heartland!

First thing is the confirm tank vent line is clear.

Next time you dump.......after it has drained go up on roof, remove vent line cap and run a garden hose down line. Then turn on garden hose and watch flow from tank.

A cut out will float around until it gets suck down against drain outlet.

The sudden rush when you first open drain valve and then slowing down sounds more like a vent problem

Second that the dealer take care of the problem. Could it be the tank isn"t vented and creating a vacumum? I like the idea of a scope going in to look.

Sounds lika an obstruction (as you mentioned) to me. The next time tank is empty try removing the valve. I suspect the obstruction will be right behind the valve. Oh....... I just realized you said your unit was a 2014 model, let the dealer take care of it under warranty. The dealer may have a camera that is suited for putting some "light" light on the issue.

Keep us posted on your findings.

On Edit: Try running a rod or wire (fist tape) up the train when the flow slows and see if you can move the obstruction. This would at least have the possibility confirming the location of the problem.

Probably the cutout. Seems to be a common problem
