Dump Valve Rebuild?

[Keith Strehle]

The next item on the list is the dump valves. They are the twist lock
type and appear to be original equipment. The look just like the Dupree
valves? Are there knockoffs out there? Are the valve bodies glued in?
If they are Dupree valves, should I rebuild or replace the gate
assembly?

Thanks, Keith

[Terry Neal]

Keith, you should contact Jeff Miller at Dupree Products
(616.355.9811). He owns Dupree now & has the valves in stock as well as
all the rebuild parts. Also,. you can upgrade to air valves if that
interests you? The bodies are glued into the tank adapter. If you get
lucky, the adapter that screws into the tank will turn out easily. If
not, you have the cut the fitting out of the tank & glue a new one in.

Will the adapter turn independent of the valve and piping? Like a
pipe union fitting?

Only after you cut the output pipe, downstream from the valve. Your
valve should be glued into the tank adapter. Mine was. Jeff covered
how to get it out with a cutting bit on a Dremel tool.

Now that there is a discussion of dump valves ... and you mention the
&^%^&% air valves ...

I really hate having to 'air up' the coach just to dump, especially
when I'm in an RV park for a week or so. It seems so silly to run a
500 hp engine just to get the air pressure to dump the sewage.

So, does anybody know if
1. is it practical to re-route the air valve source to the auxiliary
compressor (used to provide air to the Microphor toilet) -- and will
that compressor be able to provide enough air to efficiently operate
the air valves without stressing the compressor, or
2. what are some of the alternatives (and costs + ease of
installation). Are electric valves a good idea? I certainly don't
really want to hassle with manual valves... the switches are close
enough to the sewage as it is...

When in an RV park, I usually go 3 days between dumps or I dump on
the day we leave... It's not like I do it all the time, but I have
noticed a few strange looks from neighbors after I've 'aired up' to
do a dump.

So your auxilliary pump only does the Microphor? Mine will fill
anything/everything, including air bags. It cuts out at 90PSI.

I like being able to have full-usable air before the engine is even started. The
8V92 doesn't need a long warmup (my opinion, anyway), so I can roll soon after
startup.

OK, I'll bite. You don't have an aux air compressor that pre-loads
your chassis air tanks, which is then used to power the dump valves?
That's the way my 91 works. I thought all the late 80s and up had that??

I don't have air valves Pete. I just mentioned them so Keith could
consider them as an option. I know there are electric valves out there
too. Believe they are 12 volt.

I don't see why you can't power your waste valves from your aux air
system if your aux compressor is plumbed into your coach air system?
Should be an easy modification for your coach I think.

That's what most people are doing with an aux compressor anyway so you
don't have to fire up that big diesel to have air to leave a campground
or to dump your holding tanks.

I have an aux compressor that I will plumb into my coach air system so I
won't kill any neighbors on a cold Detroit start up.

As things are currently arranged, the auxiliary compressor only does
the toilet. It cuts in around 65# and cuts out at 90PSI. I'd be happy
if it did the dump valves. The suspension/brakes -- well, I'd just as
soon leave those alone. Anyway, I don't mind waiting for the air for
a departure ... the series 60 doesn't take all that long to
pressurize the system --- I usually run it to air up while I'm
raising the HWH jacks anyway, so it doesn't delay a departure much.
(I still go and visually check the HWH jacks to make sure they're up.)

I am going to put in an auxiliary compressor just to do that, I hate starting up
the engine just to dump as well.
