macerator...

[RonE]

 I tried using the macerator pump this week for the first time and I am now experiencing a head smell. I see now that the macerator itself is leaking. Has anybody else experienced this problem.  Not sure if its original, but I guess it just needs replacement.
Thanks,
Ron E

Ron, macerator pumps are "notorious" for failure, especially the Jabsco units.  Yes, it's easier to replace than to try to repair.  If you're sure it's not the hose fittings and clamps...  Sometimes simple lack of use kills 'em.

Hey Stu,
Yeah its a Jabsco, and the drip drip leak is coming from the unit. Curious, what did you and most owners replace there Jabsco with.
Thanks RonE

Wrote about this a few years ago.  We had a fairly new Jabsco and when checking it the night before a cruise, it literally twisted itself in two.  When checking with the yard, they commented that they saw dozens of these failures and highly recommended a Shure replacement.  We went with their recommendation and have had no problem so far.  We also made a warranty claim with both West Marine and directly to Jabsco.....West Marine just laughed and Jabsco never responded.  Go with the Shure.  Hope this is of help.

Hey Stephen,
I picked up the Shurflo macerator today at defender.
I will install next week after I return from a week in Casco bay in Maine.
thanks

my macerator went out yesterday while I was testing it. It was a jobsco and rarely used. I went to West Marine and they make a replacement mascerator under their name.. I think about $140.00 (less than jobsco and Surflo)  Replaced the other unit easily. Not a pleaseant job in the bottom of the boat in 90+ heat and Florida humidity. .

I started a  thread here a couple of years ago when, in replacing my broken macerator, I created a s#&t storm for the ages.  It had a happy ending but I will repeat Peggy Hall's advice to me.  I bought Pure Ayre on line to kill the odor and it was the critical piece to returning my boat to habitability.  I was led to believe that with the degree of spillage into the bilge I might never get rid of the odor but in a short amount of time it was completely gone.  Good luck to my fellow macerator failure sufferers.

Just to follow up..
I installed the shurflo, which wasnt so plesant. I had to replace the 20$, 1-1\2 elbow as well.
It s working fine.

I'm thinking of replacing my hoses the end of this season.  Was thinking of pumping out the tank.  Filling with fresh water then running the macerator to get rid of all the fresh water and to clean out any left over residue.  Once I get the tank empty.  How much water/waste can I expect to come out in the piping once disconnected?  I'm hoping to create as little mess as possible.

Hi,

If you empty with your macerator pump, you shouldn't have to much left.
I did a good pump out before our last winter houlout, and I removed the pump.  No mess came out 
Since we sail on a Lake, pump is not allowed, it should be disconnected.

I had a LOT of rags placed under the fitting and a good pair of rubber glove, just in case.....
Not a fun job

 A couple of suggestions based on bad experiences
Put a lot of cheap dish washing liquid in the tank and fill it half full and let it slosh as long as possible before pumping out.
Then flush with as much water as you can.

Go the grocery store and get a couple of disposable baking pans of the biggest size that will fit and several rolls of paper towels, put several layers of paper towels against the hull and in the bottom of the baking pan.

Form the baking pan to to fit under the joint and be careful!

I'll second the Pure Ayre recommendation. ( Wash with Dawn, rinse, spray the area with a strong bleach solution, rinse, rinse again and pure Ayre it)

I've replaced holding tanks and plumbing on my last 3 boats and have it down only an objectionable jab compared biological warfare the first time!

I would agree with the advice from JR.  FWIW when I did this I used baby diapers instead of paper towel.  Not really sure if they are more absorbent but they have plastic on one side to keep the "stuff" from seeping through.  I  tried to do it on a morning after things had frozen but that did not work as expected as "stuff" flowed quite well.  Why is it that the PG works well when you don't want it to?

Mine was leaking too.  I had the tank fully pumped out, flushed, and pumped dry.  I was able to use a standard plumbing plastic cap from the hardware store to seal off the tank and remove the mascerator.  I intended to buy a new one but reconsidered when I saw the price for a new one.  In my case, the long threaded bolts holding the grinder to the motor were rusted away.  Tacoma Screw in the Pacific Northwest sold me long threaded stainless rods from which I replaced the missing bolts.  I cut out my own gaskets from automotive gasket material and reassembled and reinstalled it.  I would never use the damned thing in Puget Sound but wanted a workable mascerator in place for the long cruise I intend to take next year. . . just in case.

Dave,
Along with all my other "Great Ideas" yours has just been officially stolen!

I had never thought about using diapers for their intended purpose!

When I changed my hoses 2 seasons ago and then removed the holding tank this month... I used a small 5 gal shop vac for when the hoses come of to catch the remnants that pumping out and "mascerating" can't pull out.
I lined the area with about half a roll of paper towel which only caught an ounce or so.
At least you can clean the shop vac out in the open. 

I used pureayre prior to pulling my tank out and it worked only for a week.  I finally had to paint the compartment the tank resides in to stop the "off" smell in the settee compartment.  I also painted the tank with plastic primer and then oil alkyd rustoleum.   No more smell.  The reinstallation did not include the macerator... even though I may go in the inter-coastal in the next few years.. I'll just plan accordingly without it.  (can't use it inside the inter-coastal anyway)  My tank from Tank Depot arrived without NPT threaded holes and I was not about to follow their advise to use thru hulls and a inspection plate.  That's why we painted the original tank after a more than thorough cleaning.  Some day maybe I'll have fittings welded into the new tank.
