HI - I have a 19' international (new to RV'ing) and have set-up a nice pad beside my house with 30amp elec, connection to my satellite dish on the roof, fresh h20 and the last item is to create a sewer connection. I was thinking about getting one of these (Portable RV Waste Pump > Toilet Waste Pumps > RV/Caravan > Flojet - ITT) which I've seen advertised (it macerates and send the effluent out a standard garden hose) then asking my plumber to run a Y off one of the existing waste stack pipes in my basement (conveniently close to the exterior wall where I'm parking the RV) with 2" pipe up and out the side of my house near the RV with a screw cap on the cover. Then, when I want to dump, I can connect the macerating pump to the RV, put the other end into the 2" pipe coming out of the house and "let 'er rip". The pipe into the house will be higher than my waste outlet on the RV (by about 36 inches) but the flotjet pump is advertised to be able to pump up to 25 feet away and up some height. This solution sounds like it will work but I'm not certain. Has anybody done this? Did it work? Other suggestiosn?

Thanks

We dump at home using my Sewer Solution with 40' of Sewer solution flex hose and 30' of 1" pvc. We run it right to our sewer clean-out .

You should have a sewer clean-out somewhere outside the house.

I bought a Flojet macerator and ran a simple garden hose to the sewer clean-out on the side of my house. Works like a charm.

I am contemplating the same idea. I presently have a 2 or 2 1/4" pipe that comes up from the washing machine drain. I can tee of that pipe at a slight angle to get the new inlet where it would be closer to the RV drain. The unit advertises that it macerates the waste and can send it in a standard size garden hose several feet to the new drain. If any one has experince with this setup or suggestions, I would surely appreciate your response.
thanks,
Barry

I would not put my black tank down my washer drain. If you experienced any clog in that line, it could be a major problem.

You should have a plumbing clean-out somewhere out in your yard along the line to the sewer in the street. It should be a capped 4" pvc line at ground level.

Barry,

I have been using a maceration since we bought our trailer in November of 2007. I have used the 4" slinky hose twice in that time.

Keep in mind that we are full time in the trailer and I dump the waste tank every 10 to 14 days.

I find dealing with this set up to be much cleaner than the slinky (stinky) hose.

My suggestion is to heed the manufacturers recommendation that you use a minimum 3/4" hose. I started with a 5/8" hose. The difference between the two is great. The pump does not have to work anywhere near as hard with the 3/4" hose. It runs much cooler as well which has to have a positive impact on the longevity of the pump.

When we are at my in-laws I pump uphill 75 feet to a drain that is 2 feet above ground level; it's going to be a sink drain one day in the future for an outdoor kitchen in a breezeway.

Good luck,

Jim

Sewer Solution is what we use at our house. I have had up to 3 trailers there at one time and the clean out is uphill from where they are parked. We would just schedule the fun for one morning a week

does everyone have this? how to start looking? should i start from the sewer stack in the house and walk out to the road, looking along that straight line? Our sewer stack is at the back and i am thinking it would go out to the side road but it's strange that I have never noticed it - been here ten years and have dug up a lot of "stuff" including the weeping tile etc. Would it go under the house to the front?

blacksheep · 05-07-2009, 06:13 AM

Older houses were built without sewer clean outs but may have had one added since the house was built. Won't hurt to check. See if the sewer department will send someone out to show you where your line taps into the main sewer, then backtrack from there to the house where you think your line exits the house.

Godspeed,
Trent

I do the same as Brian....I have a sewer line clean out "poke through" that give me access to my city sanitary sewer system, but the same could be held true for a septic system.

Simply attach your waste flex hose to the "poke through" and dump. Flush and you're good to go. If you don't have a poke through, add one. It's not difficult and you don't need any fancy tools or pieces of equipment to do it. My house is a 50s ranch that had none before I moved in. I now have one and it was simple to add (though if you don't like to dig, it could be a chore).

Shovel, PVC, and that is pretty much it.

Silverhobby · 05-07-2009, 06:17 AM

One word of caution.....Is the place where you are planning to dump a municipal sewer system or a house septic system? House septic systems depend on bacteria to break down waste and toilet paper. Many (non green) formaldehyde type chemicals work against a home septic system. FYI

Hey Brian, I was thinking about doing this. My clean-out is right next to the side of the house where I park my Airstream, so I could easily get a slinky to it. But I wasn't sure how to remove the cap? The PVC cap has a very large, square knob on top. Much larger than any wrench I own. Is yours the same?

Marcus,
Do you mean something like this...

If it is you can get a pipe wrench to fit it and remove it. We have two four inch clean outs in out septic system and I only have them finger tight so I can remove them when I want to dump the black tanks.

ticki2 · 05-07-2009, 07:10 AM

With a septic system is there any problem dumping 20 or 30 gals all at once ?

bkahler · 05-07-2009, 07:16 AM

I would also like to know about dumping the holding tanks into the septic system at our house.

Anyone "been there, done that?"

Thanks!

Great thread. I've been wanting to do this as well but haven't found the 'clean-out' with the square topped cap anywhere. If the city sewer line is under the middle of the street, wouldn't the house sewer line head that direction but off to the side of the house? If I call the city sewer dept. will someone really come out to the house? If so, that would be great.

Here's another option

Yes, our cleanout is about 5' from the house in line with the cover to the septic tank. I coated the threaded portion of the cap with silcone grease to make it easier to remove and replace.

easyride · 05-07-2009, 07:42 AM

They will here,and mark where their lateral is supposed to be,then you must try and figure out how your plumber originally ran it out from your house.

Good to know. Do you use any types of chemicals in your blackwater tank? I've read that some are harmful to septics.

Thanks!
