Dumping a black tank of MH that has macerating toilets

[Stutch]

Hey all!!! Our new Newmar 4018 has 2 macerating toilets. Anyone have experience with the process to dump the black tank WITHOUT having to use the 3" hose?

My thought was that a sewer cap with a standard 3/4" hose and let gravity do the rest. Does this sound right?

If you've done this what are you using for a hose?

Thanks

Our rig has a macerating toilet and a sanicon on the output end.

The sanicon worked great when it was shot, now that I rebuilt the pump it is AMAZING (it's not slow anymore, dumps every bit as fast as the slinky did!).

I've had a regular RV toilet. I've blown out a cheap slinky, got the T shirt. Have 2 rhino hoses in the basement, will never use them again.

The full macerator system is the only way.

sounds to me that a jet cap is in fact the sewer solution. and getting away from the misery of a stinky slinky was exactly the reason I went with the sewer solution and macerator pump. if you enjoy playing with those stinky slinkies, good luck. filthy to use, filthy to clean, and horrible to store. other than that they are a great idea.

Hookup is no harder than with a 3/4 inch hose

Only time I use the 3/4 inch with macerator is when I need to pump UP. or a very long distance.. NEVER if doing a straight dump.

I have a macerator. I choose to use the 3" hose whenever possible. I have had two unexpected clogs on the macerator. And blown the 20 amp fuse 5 times.

The 3" hose is not that big a deal. Nowhere near as bad pulling the handle on the black, and having the macerator stall!

Holstein.. The Jet Cap, as I call it, is the cap that fits over the MH 3" pipe and sends a high powered jet stream of water down the hose. Basically, it pulverizes and shoots the black tank contents down the 3/4"hose. Pretty neat.

In my case, since the contents of the black tank is already liquefied, this will make sure I never get stuck with a clog.

What's a "Jet Cap unit"?

I use the three inch hose, black first, than grey, rinse with water, put up hose. Wash hands before I close the door, and good to go. Mine has the maserator but would not trust to drain through a 1 inch hose without pressure.

Thank you all for your suggestions. One thing I am guilty of is OVER ANALYSING and being a research nut. During an RV Show, I asked a parts supplier what I would need to empty the tanks with 2 macerating toilets. They told me a clear cap and with a hose connection and let gravity do it. So, I bought a clear Valtera for $3 on Ebay and the sewer adapter from Sanicon. All I need now is the hose.

After many trips to Home Depot, Lowes, Amazon, and endless Google searches I found trying to find a 3/4" hose that was reasonable was impossible. I have a 3/4" water hose but trying to wind it to a reasonable size for storage was impossible.

Thanks to the discussion here, I realized this design may or may not work. I even thought of purchasing a pump to push it along the hose but that wasn't practical.

All that said, I ordered the 25' Sewer Solution extension and the Jet Cap unit. Now I have a complete Sewer Solution system. Since this is designed to work with non-macerated output I should be more than OK! I'll leave the grey tank and black tank closed most all of the time. When it is time to leave the RV site, I will dump both.

Best case, I open the black tank and it drains perfectly through the 3/4" hose. Worse case, I will see it struggling and help it along with the SS Jet. Either way, I am thrilled I don't have to struggle with the 3" pipe.

One thing I am learning... Being a Rube Goldberg is OK for some things and not so smart with others.

Thanks again ...

Is it truly a macerating toilet or is it a vacu-flush system? Confusing them could be crappy deal.

Used a Flo jet for 5 years with out any problems. New Class A we have has a center
powder room with a macerating pump to transfer to back tank. I use a portable Flojet to empty all out at home with a Flo jet, never had a problem. Just use a 3"4 hose. I bought 2 25' that are black from Graingers so they are decicated to the Flo jet

After this very dirty conversation..... I decided to get the Sewer Solution which has the 3/4" hose and uses a water just to push things along. Since it is designed for non-macerated feed it would be a good belt and suspenders approach.

Let gravity do its thing and if there is a clog, turn on the jet!

If you haven't guessed, I am trying to get away from using the 3" hose and since the MH comes with macerator toilets I'm, more than half way there!

This is the best solution. But I would not leave your black tank valve open. Eventually, waste material and especially toilet paper will build up on the bottom of your dry black tank. Just keep the gray tank valve open and keep the black closed until you dump your tanks. Run the Sewer Solution high pressure water when you dump your tanks.

Stutch-

I had a sewer solution prior to the flojet... works great but uses a lot of water to power it. If you want to try it without the outlay for a new one, I have one sitting on the shelf in my shop that I would be willing to part with. I have the sewer solution with 25' of hose and the additional 25' hose extension from them. It has been sanitized and is just gathering dust. PM me and we can work out a fair price and get it shipped up to you.

I thought a standard garden hose was 5/8", and contractor hose (about 3 times the cost) 3/4" and usually only offered in 75 and 100 foot lengths.

Are you guys finding 3/4" hose in 25 and 50 foot lengths at reasonable prices? Where? The last one I bought was nearly $100.00, and its 75 foot length is not handy.

I do not think turning on the "jet" after the 25' hose is stopped up is the right sequence of events. Nor will it be a pleasant ending.
