I finally decided to get a macerator pump and I cannot believe these things just don't come with your TH or RV!I can't tell you how much I hate waking up on the last morning of a trip and dread finding an RV dump station along the way home! Most of the time there is a line or even worse, it is "out of order" and I have to drive around looking for another station. Don't even get me going on the stations that require the driving accuracy compared to that of landing on a moving aircraft carrier!!!Anyway, $225 is a lot of money but after emptying both the grey and black (70 gallons total) in less than 5 minutes at my house....S O L D! You can either dump to your clean out drain or your toilet. Since my drain is covered somewhere by landscaping, I simply just ran a 3/4' hose from the macerator into the toilet and presto....NO WORRIES!!!I can't tell you how taking this one item of the "last day to-do list" just elevated my outing experiences for all of the future to come.Just two little things to note with getting a macerator pump:1) They will not provide you with enough wire so pickup either 12/14 gauge wire, about 25 ft will do in most cases but remember, this is to be wired to your battery IMHO.2) Get a 3/4" industrial hose or if you just have $$$ laying around, try a 1" no matter your run length, up to 100ft. 5/8 is not going to cut it so don't kid yourself.

Be sure to take it apart and inspect every year or so. The impeller wears out or breaks. Plus make sure everyone knows not to put anything into the toilet. No fun when they jam.

I don't know for sure but think that the Thor ACE comes standard with a macerator pump and there have been several posts on this and other forums with folks having issues with them.How do they handle those cleaning wipes that don't break down?

They are trouble in any kind of sewer system, and I speak from experience - I am a licensed wastewater treatment plant operator ....But to answer your question, one of these pumps might handle them for awhile, but eventually the wipes would bring things to a halt ...

I will tell you from experience that they do not like anything that did not go thru you first. Wipes, q-tips, hygene products, those little disposable bowl cleaning pads or paper towels absolutely positively will clog the impeller. Make sure you have a good pair of medical forceps or long needle nose pliers handy because someone will eventually test that theory.We use ours at what we call our Family and Friends Camprground. On a holiday weekend we might pump out 6 or 7 RV's. We have a septic system but not sewer hookups for everyone. Great item when used properly. Just like a dump station, black first, then gray.

Been using one for 5-6 years, dump at home after a trip.Lucky that the generator is close by the dump connection and I can hook up the pump wires there.I have a pair of long needle nose pliers to remove any debris left over in the impeller and a HD 3/4" hose to connect to the "clean out trap" on the house. I made an adaptor to screw into the 1 1/2" clean out fitting (1 1/2" male pipe to 3/4" female pipe) and then a 3/4" pipe thread to hose connector.Works great and no trips to some pretty gross dump stations

On my setup I ran wires straight from the battery to a quick push-to-connect at the frame rail near dump cap. Then had another quick push-to-connect on the macerator. Made it simple to plug in to use and simple to unplug and be done.

The one I have has a fuse built into the on/off handle.

This is the one I have :

Any electrical equipment should be protected by a fuse or breaker. My macerator pump calls for 25 amp fuse protection. I'm running it on a 20 amp breaker. If I start to see nuisance tripping I'll change out the breaker for a 25 amp.

Here's a pic of my built in installation. I have a 50 foot 1" hose I'll be hooking up to it. I'll post more when the install is complete.

I drain black first, grey second, then usually refill both thanks with fresh water and repeat.
The "dump hose" is pretty clean after that, and it only gets used for that, drain fully and screw the ends together and store out of sunlight..
After a few trips to some dump stations where it looks like someone just got close to the drain and opened the valves and let $#!T fly, I decided to find a better way.
Before leaving camp, if we have any ice cubes left, I dump them into the toilet just before leaving, they slosh around and help to knock off any crud sticking to the tank walls etc.

I'm not sure but from the last dump I just did, the macerator seemed faster. I would let it run for 45 seconds, stop it for 15 and then run it again at the same intervals. For some reason it seemed to drain the last bit faster than the 3"....

In any event, it works very well and clean up is a breeze. After all of the back washing, I will then hook the water hose up to the dump hose for even extra clean out although it is pretty damn clean otherwise.

Very please overall. Honestly, sitting in line waiting to dump is just a buzz kill.

I agree it doesn't dump as fast or as good as a 3". So I rinse it more with the in tank rinser and from above to get it clean. I have a three inch clear ext. so I can watch.

Same as the three inch hose: black tank first, then gray water to help flush it out. My pump has a flush port on it, so if fresh water is available you can hook that up and flush it even more. Walk the hose from the pump to the drain so the water all runs into the drain, then coil it up and screw the ends together.

Never had a problem ....

Have a flow jet, used a macerator, and have dump at home in garage near door. (Don't ask me, like that when I bought the place)

My experience- flow jets and macerators don't create enough velocity to get the "Big" stuff moving. Occasional use is great and convenient but you need a real flush time to time or you'll be building large solids that won't flush.

How long do you flush a 3/4" x 100' poop hose?
Where do you store it when "flushed?"
Do you cap the ends or would it burst from decomposition?
