Macerator system

With myself being new to rv`ing, I am complying a list of what we want on our coach. Does a macerator system a must or not. Any pro or cons comments are appreciated.

    PROS: Easy to dump. No mess, You can eat a sandwich while dumping..:W...easy to store. It's a MUST for any coach we buy. I've had two.

    CONS: Takes longer to dump. Annual maintenance, for me anyway, is to disassemble the pump and clean out any hair or debris left on the blades. Impeller needs to be replaced about every five years. $60 item, 15 mins work.

    I have a question on the built-in. Is there also a regular 3" conventional outlet on your rig for a stinky slinky?

    I would not want to HAVE to use the macerator every time because of the time and also the "whoosh" evacuation action that a suitably standard sewer hose affords. That is one of the reasons I would not want a pump-only solution and why I like my portableet Flojet.

    Another pro - you can use this when the sewer inlet in the ground is higher than the outlet on the RV - no "walking" the stinky slinky.


    The built in ones are similar to the portable units. Yes, the 3" connector is still there. Simply use the twist lock to remove the macerator hose prior to the pump and attach a stinky slinky and go for it....

    That said, having had the macerator in my Dynasty for three years and in the Exec for five years of full timing, I've never had a build up or issue with either unit. Turn it on, let it do it's thing and turn it off. I leave the grey open when camped, black closed. When time to empty the black tank, I close the grey before showering. After showering, drain black tank, use hot shower water to flush out black tank, on the third flush, I close the black tank to leave some shower water in there, and then drain the grey. Works to keep both tanks and all the hoses clean and sanitary.....Dennis

    That's good to know. Thanks for the reply. The thing I like about the MHs is that you guys have all that stuff secure and in one place in a lockable compartment. No suct facility with a TT. As a consequence it is not as easy to have a built-in macerator system that can be disconnectable to allow gravity flow when desired.
  • I have a macerator toilet and a macerator pump. I pump it about 50 ft at home. no build up.
  • I want to thank all that has responded to my question. The wealth of information saves years of trial and error and not to mention dollars spent for trying.

    Double maceration! That stuff must bypass any strainer .... :D

    What brand and model of macerator toilet do you have in your RV? I am not in love with the Dometic toilet that came with my RV and can see me changing it out at some point in the future.

    One of the best uses I saw one camper do at a camp ground was he had a 30GAL empty tote sitting in the back of his truck bed.

    He hooked up his FLOJET and pumped into the tote in the back of the truck bed. Then unhooked the hose from the trailer end and tied off high on the truck and headed for the dump.

    He then used gravity flow to empty the tote.

    No mess no fuss... The camper said one thing to watch for is to always have your tote bigger than the tank you pumping from. Said it was hard to tell when you was approaching full on the tote in the back of the truck. Makes a big mess he says haha...
