graywater/blackwater dumping in RV Park

C-Time

Still looking for the best way to use boats Macerator pump in a RV dump site. Dump site not a marine pump-out. Has anyone made a fitting to screw into the deck outlet vs holding a hose with gasket tight to the side overboard outlet of boat while a second person turns on the pump.

Hi Ernie,

I have not seen nor heard of any adaptor that would couple to a through-hull fitting and attach to a portable holding tank. Hopefully someone will offer some help for using the drains wile camping on land.

How do you like the boat? I haven't heard from you in some time, hope all is well with you and your family.

Suction cup?

I tried making a hose connection that lead to a standard RV sewer connection (photo in our album)... no joy. Let's just say the macerator output has a lot of force. The only solution we've come up with isn't great: one person holds the standard RV sewer hose over the macerator outlet with the other end of the hose in the sewer connection, while the other person flips the switch. The BIG downside of this is the clean-up and storage of the sewer hose. RVs will dump their black tank first, then dump the gray tank to help flush out the sewer hose. If additional rising is necessary, you can use the city water connection. RVs also have a place to store a sewer hose; you'd have to have a RubberMade bin or something similar to keep the sewer hose, and then the space to keep that for the occasional use. Also, RVs have the sewer outlet on the driver's (port) side, our C-Dory has the macerator outlet on the starboard side.

Also, I am not aware of any commercial RV parks that will tolerate dumping of gray water on the ground. I also made a hose connection for the sink, but find it easier to just put a dishpan in the sink of the boat and dump it in the sewer outlet of the campground. No way to deal with the showerbox output, either - we use the campground's showers.

We just make it a point to put Wild Blue in the water often enough while land traveling to make use of a marina pump-out. Oh, and use the campground bathrooms as much as possible when on land.

Some things about our boats don't easily equate to an RV. We've been able to work around this, though... with over 35,000 towed miles on the boat. We do stay at RV parks when we are traveling with the boat.

In spite of them being referred to as "boaterhomes," there are some shortcomings when on land. Don't get me wrong, it is GREAT when we are on the water, and most "RVs" don't float! Wink

Best wishes,
Jim B.

I wouldn't want to be the person holding the hose against the discharge port. Not even pretty to think about.

There is actually a step by step instructional video that demonstrates all that can go wrong during this process. Enjoy!

Well, I grew up on a ranch and shoveled a lot of poop. abd raised 4 kids and the early years were mess. So I'm not too finicky about dumping the holding tank through a hose, and I'm the one holding the hose.

I got an elbow with a rubber flange that covers the macerator output, and the other end fits into a standard RV hose. I jam one end in the sewer, the other end over the macerator, Judy turns on the switch and in about a minute, it's all over. Hose down the side of the boat, flush the hose, put it a plastic bag (contractor thickness,) throw it into the back of the truck and you're done.

As for the sink, fit a PVC fitting into the overboard outlet (file and cut,) fasten a garden hose to the end (they make adapters), run the other end into a 5 gal plastic tank and use the sink. Remember to remove the hose and empty the tank, once I forgot.

In 6 years we have had no complaints, but a lotta atta boys.

I've never stayed in an RV park but this would be one other reason why the AirHead makes sense. I just emptied ours at the end of season. No muss no fuss. Gray water seems easier to deal with.

We manage this unpleasant procedure as a team. Toni's job is to turn the macerator on and off. Mine is to hold the short dump hose over the discharge hole on the boat. I also have a bucket with water and a small amount of bleach under the fitting to catch drips and to do a final rinse on the hose. After dumping I rinse the hose with fresh water then immerse the hose in the bucket.

Toni's other job is documenting the procedure.

This site is the best. When there is a question, everyone helps with the answer. Thank you all.

sometimes I have to laugh, even though that's not humor coming out of that line.

We are currently changing the thru hull fitting (poop dump fitting)to one with threads on the outside! It will accept 2 inch hose and is real easy to use.
Under the trailer, attached to the inside frame of the trailer is 10 ft of pvc which holds the hose, just like an RV. Cept, mine gets rinsed each time the boat gets launched!

Unfortunately, I typically go with the most expensive solution ... in this case, an Edson manual pump that I believe I paid about $650 for. Works great. A few pumps and the C-Dory tank is empty. Flushing the tank flushes the hose. Very neat, very clean. Connects to the boat with the same Banjo fitting on most pump-outs ... but with the screw-on connection. We do not need it since we do not trailer anymore, so I would sell it.

In defense of my spending, in this case, we did not have a macerator.

The Sea Land diaphragm pump is only about $350 (about $250 10 years ago when I fitted one to a boat we owned so we could pump it out at our home dock).

We have tried the various variations of sewer discharge and gray water--and have ended up with a jug for urine at night, plus gray water in a pan and dump into the sewer.

I would hope that when you use the sewer hose it is at a dump station, not at the RV site. Most dump stations are concrete and you can spill some sewage and wash it down the drain. Heavy disposable nitril gloves are a real plus when dealing with sewage!

One of my future projects is to make a system for dumping at a RV campground. I plan on changing the outlets to stainless steel with NPT threads cut on the inside. I then will screw a bronze fitting with hose attached and pump away. I will put in a thread with pictures when I have it completed. Laughing
