Black Tank Handle Problem

Hello,

We have neighbors who just took possession of a Montana 3121RL. Today, they went to drain the black tank and the pull valve won’t pull open.

When they called their dealer they were told they would have to pack up their rig and haul it to the dealership. They were told “if” the dealership has. Valve it can be replaced. If valve not in stock, it would be necessary to order from factory.

Does anyone have an idea of a way to free up the valve handle I the convenience closet? They did spray some WD-40 and so far no success.

Thoughts please.

ARG!!! Bonehead dealer should know if they have the valve in stock to start with.

I hate poor service.

Call Keystone and see if you can get a mobile tech to come out.

BTW you should have started a new thread for this.

If you are minimally comfortable with tools, gaining access to the black tank valve is easy. There are several threads here about it. Otherwise you can cut a access flap in the coroplast to access the valve. The quick solution, regardless of the access technique, it undo the cable at the valve and open it by hand.

Replacing a cable or even the whole valve assembly is relatively easy. Order the Valterra kit (don't mess with the other brands) from Amazon, drop the coroplast, and change the valve. It should take no more than two hours from start to finish.

Carl I agree with you it is not a hard fix.
The dealers response to a unit under warranty is... well crappy.

How can they not know if they have the parts in stock or not?

From what I have heard, sometimes it is NOT so easy to replace. The space is very tight and in order to remove and/or install the new valve you may have to cut the drain pipe and use a rubber connector (like a radiator hose with clamps) to put it back together. The rubber connector also allows some flex between the tank and drain pipe and some say helps damage when bouncing down the highway.
p.s. This is why I paid to have it installed. Also the dealer wouldn't give me a firm quote. He said between $100 and $700 in labor depending on difficulty!!!! I think I paid $150 - 300 (can't remember)

If their valve is a cable style valve, it would be best to do away with the cables and use direct push/pull valves. Might as well fix it right and gain longer term dependability.

Thanks all for your responses. From all appearances, it looks like the metal bar that attaches to the black plastic handle, which is attached to the valve cable, that you pull to empty black tank...is stuck.

There is a threaded metal piece that goes through the convenience cabinet. The metal piece, which is inside the threaded metal piece, that should move in and out when the valve handle is pulled won’t move. We sprayed lubricant into the threaded metal piece but so far no movement of the inner metal bar, which is connected to the valve handle.

The dealer told the owners that they need to bring it to their shop on Monday. If they determine that is a bad valve, they would replace the valve....if they have it in stock, otherwise the shop would have to order the valve from the factory.

I feel very bad for the new Montana owners who are quite frustrated over this and other issues on their brand new rig.

This is why one buys an RV NEAR their home. New trailers always have issues that need to be dealt with.


And, with regards to the dealer, I believe the dealer was correct in that they may not have a specific part....who knows exactly what is going on.

They should be able to say if it is this this or this we have the parts in stock to fix. If it is something else we have to order.

These dealers charge too much by the hour to be run like Cooter's RV Fixit Maybe and see if they can fix it by what they have in their junk drawer.

In this case a simple lookup in their parts database should tell them if they have the valve in stock to start with. If not customer can then decide to go somewhere that does have the part in stock

Dealer selection is MUCH more important than any other part of RV purchase including floor plan selection.

I had the same problem and it was the the pice at the convenience center that was rusted. They kept using WD40 and some heavy duty pliers. Finally got it freed. Every so often I spray the rod with WD40.

Also good going Keystone for putting the black and gray pull handles under the water connections.

Another thought on this subject. When I was replacing the black valve I cut the drain pipe just after the wye and installed a 4 inch long spacer that has radiator clamps on each end. All RV story have them. Now I can easily slid the piping away from the tanks to replace the valves.
