Macerator Upgrade for Renegade & Other RV's - Mike Mas

Macerator Upgrade for Renegade & Other RV's - Mike Mas




Hello all - Since our new Renegade Verona came equipped with a macerator toilet, I was somewhat disappointed to find out there was no macerator on the dump valve. Since my last 3 RVís were all equipped with a macerator pumps, Iíll have to admit Iím spoiled. Once you have one of these systems on your RV, you wonít be able to live without it.



Having the ability to pump uphill or even pump into a household toilet in an emergency, is priceless. Generally when weíre heading home from a trip, we seldom stop at campgrounds, so Iíll deal with the tank when we get home, using my own 4Ē dump station which goes to the septic field.

To remedy the problem - I ordered a RecPro 12 volt Macerator Pump which sells for $129, available at a number of online stores. The pump assembly is unique since it comes fully assembled with a dump flange, so it instantly mounts to the renegades sewer hose connection. All youíll need ito be operational is a 1Ē 20-ft hose and a 12 volt supply and youíre good to go.








The RecPro Pump Assembly - Comes with a 10í power cord equipped with a switch and cigar lighter plug which you clip off. Since the switch needed to be by the pump instead of the end of the wire, I rewired it around 12Ē from the pump then secured with some tie-wraps. Next, ran the 12 volt provided wire from the third tank compartment forward through a hole on the Renegadeís battery compartment firewall, then made my connection using a fused connection on the slide power feed in the battery bay compartment.








One of the nice features of the Renegade is they (almost) separate the fresh water compartment from the sewer connection. Regretfully, the tank flush and sewer hose is stored in the same fresh water compartment bay, so I removed the server hose holder and Iíll now use the flusher on the RecPro pump instead of my fresh water bay, totally separating the fresh water from the black water tank system.





Since the RecPro does not come with a 1Ē dump hose /w sewer fittings, youíll need to purchase it separately. I happened to have an extra Thertford hose (# 70424) shown in the image, or you can opt for a Clean-Dump Macerator hose with fittings generally sells for around $50-60. Anyhow, the entire job only takes a few hours and cost less than $200 and I guarantee it makes this horrible job super easy, youíll never regret having it on your coach!

Stay Safe - Mike Mas

Nice upgrade!

I created my own macerator out of a standard garbage disposal using this kit:

https://www.ebay.com/itm/SkySight-En...item2af26f7da2

I don't use it at the campground but have it in case I need to dump at home. I went this route because I read some reviews that these 12V models can sometimes overheat and have to stop and restart and the plastic fins to connect the sewer hose tend to break off over time.

Here are some videos of assembling the kit and then using it that I found.

Thanks for the replies - Fortunately This pump uses metal impellers so that won't be a problem.

Stay Safe - Mike

It's not the impeller blades but the plastic fins that the sewer hose lock onto that break off.

You won't have that issue with your design because it is permanently mounted. In my case I connect and disconnect a 2' sewer hose so I had to worry about the plastic fins breaking from connecting and disconnecting the sewer hose. Once that happens the macerator has to be replaced.

Judge,

Hello and thanks for sharing your unique self made macerator project - very interesting what us RV'ers can do when we take a notion to do so. Concerning your thoughts on the flange, you're right the pump should be supported in some manner so its not bouncing around hanging on the flange. On my Leisure RV. I supported it with a large hose clamp to the body, where on my Renegade, I mounted a hard foam block under the pump to support its weight.

While I'm here I mentioned the Clean Dump hose set - mine arrived and was sent back the same day the hose is so stiff it was not even un-coilable and the fitting took two hands to turn, this hose is not designed for RV use and would be near impossible to store especially in cold weather.




I highly recommend that you install the Threrford macerator 10 ft or 20 foot hose since it is very flexible and stores easily. I also included a shot of my water bay hose compartment which was re-purposed to hold my water hose. As I mentioned I dislike any sewer activity in the water bay for health reasons.






Stay Safe - Mike
