First rule of RVing---don't rush. No hurry is there? Make your choice when/if it quits working or gives you a problem.

Smile Macerator or not

Goodness, thanks. I appreciated though finding a search method that someone suggested early on, but in truth the replies of all of you were concise and in one spot. I now understand why one would have a macerator; I did not before because I have a large sewer connection by our MH that we easily drain slinky hose to and in limited park visits, being new, has not been any problem. But I see how the macerator could work to advantage. i just have no instructions on bow to use it so wanted easy way out, did not visualize having to pump some distance or uphill. I wanted to gain the space by removing the thing. Conclusion: do what you essentially all said.... Use the slinky hose mostly, learn how to use the macerator, keep it as an option since not have to buy one. Really, your patience and explanations are big help to novices.

Nutravlr.....There are some other uses for the macerator. On mine, the two tanks, grey and black, are mounted side by side. They both drain into a single outlet that goes to the macerator pump. We often take short weekend trips to a local park where we stay in overflow without hookups. At the end of the weekend, I can flush my black tank without a fresh water rinse.

You dump your black tank using the macerator, turn it off and then open the grey tank valve. The water from the grey tank will fill the black tank and equalize. Once the water stops moving, close the grey and pump the black out again. You essentially are using soapy grey water to rinse out the black tank. I do this twice and then dump the rest of the grey. No need for flushing the black tank.

If you're ever boondocking and you're about to overflow your grey, just open both valves and let the gray flow into the black. You rarely fill the black. This can extend your stay.

Simple answer.

Macerator's are great for emptying tanks where you need to go uphill, long distances or do not have a standard 3 or 4 inch sewer dump opening.

Standard 3 inch Slinky's are great for a fast tank dump and cleaner tanks because of the whoosh factor.

Macerator's work well until they get clogged, then you will be in for a Robin Williams experience.

Slinky's work well until they rip open although i would definitely recommend the Drain Master hose for longevity and lifetime guarantee.

Our unit, with relatively small tank capacities, gives me the option of which I use because each tank has an electric/manual valve that opens to a single pipe with a Tee. The straight part of the Tee goes to the macerator inlet and the other exit has a conventional capped 'stinky-slinky' connection (I normally use the macerator but do carry a new slinky 'justin case').

Our unit also has fresh water flushing for both tanks, which I use after doing what Diplomat Don has recommended.

I find there is no need to rush the job and do the best I can to leave the entire system as free of black tank contents as possible.
