Waste Valves
« on: August 03, 2017, 01:40:01 PM »
I need to replace my black water valve on my 2007 5th wheel Keystone Montana because it is leaking a little.  I thought while I was doing it I might as well do the grey water valve too.  Does anyone know what size they are?  I would assume the black water is a 3" and the grey I'm not sure.  Would like to hear from a Montana owner that has replaced these valves.  I watched a video but of course all brands of RVs can be different.
Thanks
Oh, also I am hearing things like make sure it's not a cable valve and are bristol and valterra valves interchangeable?  Now I'm getting confused.

I'm not a Montana owner but I do have a Keystone Hideout 5th wheel. The valves should all be standard, though, as far as I know: 3" for the black and 1-1/2" for the grey.

Same here and I have a Montana.  See below.

ok, thanks to you both.  They are just normal valves not a cable type right?  I called Keystone and talked with some guy who said they are all 3"  including the galley.  That does not sound right to me and I told him so but he said "no, they are all 3"".

I'll take that back what I said. The black water tank and the gray water tank right side by side are both 3"  The tank for the kitchen is 1 1/2". I forgot. They are all operated by a cable.

I don't know if there is any difference. You should be able to get by with just changing the 2 rubber seals. The gate slides in a groove and it may be just some crap is stuck in the groove preventing the valve from shutting all the way.

Save yourself a lot of work.  Get one of these.

What he's saying is put this valve on the end of your sewer pipe. I also have one. It's a good backup valve. You can also transfer water from 1 tank to another tank while boondocking if one tank gets full.

Valterra makes both a cable actuated valve and a valve with handle, both sold on Amazon. The cable valve has a different housing and a hole in the valve stem to attach the cable. The standard valve is treaded for a handle or an extension. I am having problems with my black waste valve as well. Was set to buy a replacement valve and change out. On a lark, I clipped the the cable wire this weekend and it appears that the valve will now close fairly easily by hand. I ordered two new cables and hopefully replacing them will do the trick. It's the "shade tree" mechanics credo - replace the easiest and cheapest part first. It might work. If not, I will replace the valve also. The cables are the weak link as they get stiff and virtually inoperable. If they are not installed properly they will develop a kink and will never work.

A valve should me mounted with the handle up, or at least no lower than 90 degrees.  The twist-on valve is usually at a downward angle allowing "stuff" to flow into the valve body gumming it up.  The first time I had valve trouble and installed my new twist-on valve, it was too loose to drive with it on.  If you have one of these things for backup, test fit it before an emergency happens.

Here's something to consider when placing a stop gate at the discharge end of your RV collection system due to an upstream leak: a 1.5" pipe 20' long will hold approximately 15lbs of liquid.  A 3" line 20' long will hold around 60lbs.  Eventually you could have a bunch of weight hanging from the underbelly of your RV; weight that the collection system was never designed or intended to travel with...
I point this out because the lines on our TT that are emptied via a cable don't appear supported well enough to travel with full.  They're also tucked above a corrugated plastic bottom on our TT - but that's another issue...

I've considered a twist-on valve since our 3" pipe runs about 3' past the black valve. No matter how long I let it sit after closing the black valve, there is always maybe a half ounce that drips out of the pipe as soon as I uncap it the next time.
