MACARATOR OPINIONS?

My coach came stock with one. I only use it when the distance to the sewer is too far away for me to use my slinky, It seems to work fine but takes too long for normal dumping at a dump station as far as I am concerned. I have have already had to replace the impeller in mine once not a fun job.

I use a flow jet macerator pump to do the same thing as you are talking about. I have been using it for 10 years and it has been great. I have replaced the impeller twice in all those years. I use 3/4 hose from the macerator to the plumbing and 50" would be easy not sure about any longer as that is all I have to go.

It's spelled macerator, and I've used one a few times. They draw a lot of power so I clip mine directly to a garden battery.

I have used one for years at our old house to pump out at home vs stopping on the way home from tailgating.

Pumped uphill about 80' away.

They WILL jam if someone puts something other than tp in the toilet.
Not pleasant.

The impeller does wear out )vanes break off) so it needs taken apart, hair cleaned off inspect/replace impeller every few years.

It is also slower than the 3" and requires more rinsing as the tank drains slower.

I use one. My clean out is about 38ft from the clipper and using the slinkies was always a pain as I either had just too short to reach or too much excess. I use the Flo-jet portable version. I hook it up to the RV battery (while plugged into shore power) with jumper cables. I have a 50ft 3/4" hose on a reel and only unreel what I need. The pump works great. For me, it doesn't take any longer because I don't have to "massage" the waste through 40+ft of slinky hose (having to pick it up along the way so the waste continues to drain instead of coming to a standstill mid-slinky).

My waste tanks are each 20gallons. It takes about 10 minutes total to dump.

I wouldn't go back to a slinky for anything.

they are head and shoulders above a standard stinky slinky. much cleaner, easy to use, no slinky to have to rinse and have drip on your shoes and the ground. if you limit them to the proper materials clogging should be at a minimum. put a standard tub drain screen in tub and you won't have hair clogging them. get one with a grey water bypass and any show debris won't clog it up.
I switched from stinky slinky, to sewer solution, to macerator pump. much easier to store a hose vs a slinky.

I have been using this for years. I pump 75' thru a 3/4" hose. Never a problem.Macerator-pump

Thanks for your input. Wanted to see what your thoughts were before I spent the cash

When macerator is high-tech pump, it is expensive on the long run and you have to be familiar how to take it apart and replace wear out parts.
Check Sewer Solution, what is very good alternative without the bad side of macerator.
The only aspect SS looses to macerator is need for water and lift, but still with good water pressure it will lift several inches.
Even on campgrounds I rather use SS than 3" stinky.
Shower water drains immediately when on last day of stay I hook up the water and flush black tank.
Way more higenic.

These things typically run about $300-$400. I've had the built-in one on my previous RV and didn't like some of the limitations - couldn't run a grey water bypass or dump with a slinky. My current RV doesn't have one built-in, but I had enough spare parts to build a portable that I used to dump at home thru a 3/4" hose and it has a grey water bypass. It doesn't interfere with my use of the old slinky dump either.

Anyway, while engineering it I put together a parts list and instructions on how to assemble one and while doing this I found a model of macerator pump that was pretty inexpensive. You can build a portable 12v macerator dump pump like mine for less than $100 that works with the 3/4" garden hose. If you want one a bit fancier that uses a flexible 1" hose the overall cost is about $200.

My design will work on any RV that has the standard 3" bayonet dump and access to 12v. You could also just run longer wires to reach the coach or chassis battery and use a temporary connection like clips to the battery posts to power it.

If anyone would like my parts list and build directions along with suggestions of where to get the parts, just drop me an e-mail and I'll send them to you.
