Holding tanks-not necessarily holding

We have used our Impact 311 for two trips now. The only real thing I've found so far, is the black and/or gray water tanks seem to leak fluid into the dump lines while being used. Each time I've gone to open the pipe to hook the drain hose to it, I get grey water (hopefully-not black) come flushing out. Like two gallons worth. Needless to say, this isn't making me happy. Has anyone had this happen, and if so how can I adjust this so the valves close completely?

I would put water in both gray water tanks and take it to the dealer and tell them to open the cap and find what valve needs replaced or adjust the cable.

By all means, the dealership should repair your leaking valve. You may have some toilet paper, etc caught in the black tank valve (if it is leaking) or even a defective or damaged seal on a valve. There should be no water/waste leaking when you remove your end cap to connect a hose.

If the dealer can't get you in for repair soon, you can always buy a "twist on valve" to replace your end cap, then just install the cap on that valve. Then, when you remove the cap, there is a "terminal valve" that would stop any flow of waste until you have the hose installed.

Many of us use this type valve as a "last catch" for anything that could possibly find its way to the dump connection.

Here's one type: http://www.campingworld.com/shopping...on-valve/27868

Have this on a brand new unit. When i de-winterized it for the first time I took the opportunity to determine what drained to what tank in the RV, and to confirm what lever dumped what tank.

When doing this test, I had this issue. Discovered it when I opened the cap, and a bunch of pink stuff dumped out...

So, after I did the test of which tank is what (gets from the trailer and drain valve), I put a few gallons in each tank one at a time and let it sit for 10 to 15 minutes each. This narrowed it down to being my Gray tank... Dealer is hopefully pulling the bottom off today to check and most likely replace the gate valve...

I have this on my fusion 342, though it's not generally 2 gallons, and it's always gray water. I presume that it's my secondary grey tank. My dealer said the valves were fine - that it's the water that still lays in the long run of pipes from the gray tank to the empty. That when the trailer is level and emptied, that some water always lays in the pipes (or maybe I don't wait long enough for it to fully drain). I've explored two options...one is the type of end cap that has a hose attachment - where I can put an old piece of garden hose on it, put it over the sewer and let it fully train before removing the endcap. The other is what I generally do - I put a bucket under it before I remove the end cap - water drains in bucket, I dump bucket in sewer drain. It's annoying, but as long as it's not black water, I can live with it.

I get a little come out when I open my drain cap as well. Appears to be grey water. Maybe a cup or two worth. Certainly not gallons

Thanks for all the replies. It clearly isn't toilet paper in the valve, because this happened the first time I removed the cap-before we used the unit. They're checking into what I can do, because they are like 150 miles away.

Some times the factory will leave debris in the tank from drilling or dropping junk down the drains. Some times it's no more that a piece of plastic that isn't letting it seal. Or a broken seal from the trash. On the TH I have now I had some trash come out of the drain on a gray water Drip line I had set up. It plugged up the 1" line I had hooked to it. But I do see some peps install a valve made with clear plastic at the connection. This helps to see if ya have gotten all ya black water out too. Hope ya get it fixed soon

I've had the problem with my last two trailers and both times it was debris from cutting the various holes in the tanks and/or globs of hardened glue that was not allowing the valve to close. Both times I had the good fortune of it being the black tank and both times I got a lazy dealer who song n' danced me about residual liquid/normal or some BS to that effect. As usual I fixed it myself.

I would fill tanks with fresh water and cycle valves a few times. They also make an sewer cap with a garden hose connection- this can be used to run water backwards.
