Dumping tanks into home sewer?

My house uses the county sewage system and there's a sewer "trap vent" in front of my house that is easily accessible. I've searched for answers, but am coming up short.

Can I dump my black and gray tanks into this vent? I would use a Macerator system for easy flow (looking at the Sani-Con Turbo 300), just want to make sure I'm not going to mess up my sewer system in any way.

Honestly ? I couldn't see where that would be a problem. Others may have some reasons, but I can't think of any.

Since you are using the sewage treatment facility I cannot see an issue other than if there is any spillage that can happen sometimes. I have been told that houses on a septic tanks shouldn't due this because the chemicals we use to squash the smell can kill the necessary bacterias in the septic tank. I am no expert in the sewage field, but that is what I was told.LOL

This was true when everyone used the blue chemical loaded with Formaldehyde. Most Black Tank Chemicals today are usually marked "Septic Safe".

As for dumping where suggested in opening post, if certain it goes to the main sewer line, go for it. Vent lines can't be used for pernanent hookups but for an occaisonal "dump" everything ends up in the same place.

Might be a good idea to flush the line with some clear water after dumping black tank to make sure all the "smelly stuff" goes down the drain and doesn't sit in an area that isn't regularly flushed from daily use.

It can be done but you might want to check with your public utility as in some areas this is not allowed as the sewage fee is based on water usage (water meter).

We have been using SewerSolution to dump our tanks into a clean-out access in our yard. It has worked great except for the one time a guest flushed a "flushable" wipe - NOT a good experience. Only concern in your situation is the height of your vent - the SewerSolution will flow uphill, but I'm not sure how high it would go.

If you live in a town with very strict regulations, it might be a problem. But normally, you should not have a problem. By the way, many municipalities do not allow these vents and some municipalities require them. In the majority of municipalities that require these vents, it’s location so near a window, does not meet code.

Thanks for the quick responses. I now have another question; is the Sani-Con system worth the extra $200+ over the Sewer Solution system?

I would not recommend dumping into a trap vent. This pipe is meant for airflow to keep the system from creating a vacuum lock in the pipes. It needs to be clear. Not even if you plan to liquify the waste first. Instead, find your home's clean-out and dump there if it is easily accessible.

In our previous home I made a dump station by tapping into the main line to our septic tank, saddled it with a T and came up with a pipe with a threaded cap. But this may not be something you can do being on a county system without getting the OK, permit, or even a licensed plumber depending on local codes.

Here at our current home I put in a dump station during our build, complete with sloped concrete around it to funnel any spills.

It would probably be a good idea to check with your county first before investing in that macerator....

Clean-outs work great. I've used them at two houses and what's nice, you open it, insert your macerator hose, empty and flush your tank, replace clean-out cap, and nobody is the wiser. Nor permission needed.

I've even used 1-1/2 inch "Pump discharge hose", the blue stuff that rolls up flat like fire hose with an adapter on the trailer discharge and an adapter to fit the clean-out. As long as it's downhill from TT to clean-out this works great and the hose is relatively inexpensive.

Home Dumping

I'm not sure about dumping in a "vent", but that looks more like a "cleanout". I have a cleanout that's much lower than my trailer dump pipe. I ran a 3" PVC to near the cleanout and then hook my flex hose to it and into the sewer cleanout. Its there only while I dump. Some sewage systems may charge you more if they know you are using the home system for your trailer / RV.

I dump into a cleanout in my garage floor. The sewersolution pumps a large amount of water with the waste so should not be a problem. Been doing it for several years with no issues. I would pump some water down it out of a hose and ensure it can handle the volume. You can also run some water in the house and listen at the opening to hear if it is running into the sewer.

I am sure happy that I am just a plain old country boy that does not live in the city with all of those rules. I have what is known as a mechanic sewer system that treats the sewage from our home and pumps clear water into the roadside ditch. I would not recommend drinking it, but it does not have a smell to it. Now if I decide to empty my black holding tank into my system, it will be no ones business except my own. If I do break any parish rules, I will wait until the parish tells me that I cannot do that.

This is true where I live. This got me wondering 1) the water in my tank came from them and was metered so it should a "wash" and 2) how can I get a credit for all of the water I used and dumped elsewhere?

Cousin Eddie just shoves the sewer hose to the curb storm drain and pulls the handle!

I have had good results using a system based on water pressure. It empties into a 3/4 inch pvc, garden hose or whatever you need to get you to the drain. Depends how far you need to push it. I have gone more than 40 feet and slightly uphill with 3/4 pvc. I am certain it will go as high as your drain in the photo. Just crank up the water pressure.

I just looked it up and found exact thing or something similar called a Valterra Kit. The photo sure looks similar. I am currently not near my home to find an exact match. $80.00

I used to live where that was true, sewer fee based on water usage. But it did not take into account that LOTS of that water did not make it into the sewer, it was used to keep the yard and plants alive.

Personally I would not worry about it.

You can get the Valterra Sewer Solution pump for $40 from Walmart.Com. Stop at a big box store and get a 3/4" garden hose. That will give you about 75 feet of dump hose. I think the SS will push output to 3 feet higher than the trailer dump outlet.

I've been using a SS for 2 years. It works as advertised. If not going up-hill, you can keep the input water off except for some wad of paper coming out to plug the outlet. Then a quick blast with water gets things moving again. When done, a 30 second blast of water cleans out your dump hose.
I primarily use the SS when on FHU sites. Little worry about holes in the hose.

You may want to consider installing a "Y" connection low to the ground of the vent line. Thus creating a new, lower location. to dump your tanks. That will still allow the vent to be utilized for what it was intended. Know of a few people that have connected their sewer line to the curb in front of their homes for easy dumping when at home. I have water and electrical to my curb, I am contemplating installing a sewer line to it as well.

Good Luck with what ever you do.
Cheers
David
