| Not knowing what the "solid substance" is makes things a bit
tougher. Did someone put something into the head which hadn't
been previously orally digested ?
If the substance is biodegradeable, I would suggest pouring some
liquid holding tank solution through the deck plate discharge or
from the head. You can buy it at any chandlery. The solution may take
a day or two to break the substance down enough to be able to pump.
Another possible solution would be to disconnect the 1" pipe from
the pump leading back to the head. Straighten the pipe and insert
a wooden or PVC pipe to clear. You probably can't perform this
procedure from the head side due to the curve of the discharge pipe
as it passes into/through the bilge.
As a last resort, I would disconnect the head discharge pipe. Tape
a "snake" to it and then plug the pipe (wooden plug, rag, tape,
somthing you can throw away :>) ). Disconnect the other end of the
pipe (at the pump ?), plug it too, and then pull the whole thing
out.
This last suggestion risks the obvious mess, plus the fun of resnaking
the pipe back in once you've eliminated the clog. The taped "snake"
should help though.
Good Luck !

| 941.2 | Look at the mascerator again | CSSE::COUTURE | Abandon shore | Thu Aug 11 1988 11:20 | 4 |
| Double check the mascerator pump before you go through everything
mentioned previously. Catalina 30's are notorious for mascerator
problems - maybe they just got a bad batch from Jabsco.

| 941.3 | SOME HELP ? | LAGUNA::MILLMAN_JA | | Thu Aug 11 1988 11:48 | 13 |
| I'M NOT SURE WHAT YOU MEAN BY "THE MASCERATOR PUMP WONT PRIME" THIS
PUMP CAN OPERATE DRY, SO I WOULD DISCONNECT THE LINE AND SEE IF
THE PUMP ITSELF WORKS.
WE USE A MASCERATOR PUMP IN OUR GALLY SINK AS A GARBAGE DISPOSAL/PUMP
OUT PUMP SINCE OUR SINK BOTTOM IS NOW BELOW THE WATER LINE. WE'VE
RUN THE PUMP DRY MANY TIMES WITHOUT ANY PROBLEMS.
GOOD LUCK

| More defails:
The pump does not start to pump anything out (no water ever gets
to it) The rubber "impellers" heat up and start to make a totally
different sound.
As far as I (and my father know) only biodegradable substances when
down the head. We just put converted the head from hand pump to
an electric pump.
I wanted to put in some liquid plumber!

| 941.5 | Metal tank? | AYOU17::NAYLOR | Purring on all 12 cylinders | Fri Aug 12 1988 05:27 | 9 |
| Can't add any suggestions - except that a Jeaneau owner friend had
a blockage from his tank because the tank was metal and a chunk
of corrosion on the inside bloked the tank exit. Had to remove the
inspection plate and go in from there .... Nuff said.
On a lighter vein. the charter company I hired from in Greece last
summer said they pulled a pair of women's panties out of a blocked
outlet hose!

Plastic tank.
re: back_a_few
My father has had this boat for two years. He moved from a
Pearson 26. The previous owner said "I replaced the macerator pump
at the beginning of the season". From the looks of the motor, I
don't think he did. My father also heard that the Cat 30's do have
problems with the pumps but noone seems to be able to say specificly
what the problem is.

| 941.8 | collapsing hose? | GRAMPS::WCLARK | Walt Clark | Wed Aug 17 1988 08:51 | 10 |
| Since many of these hoses are multi-ply it is possible that the
inner layer of hose has separated from the reinforcement and
collapsed. Since the reinforcement ply supports the outer layer
of hose it is not visable from outside.
This is a very common problem in other applications, perhaps worth
looking "into".

| 941.10 | You may want to change the hoses long-term | OBLIO::STONE | | Wed Aug 17 1988 17:15 | 9 |
| As with Walt's reply, if you have to do some extensive rework to
the plumbing, you may want to replace the flex hose with one that
has smooth insides. Many times the ribs in the flex hose trap
particles and will continue to build up a blockage (also causing
odors).

|
| 941.11 | already smooth | CADSE::MCCARTHY | Fixed in previous release. | Thu Aug 18 1988 06:55 | 10 |
| I think the only piece of ribbed hose is from the head to the Y
valve and from the Y valve to the thru-hull or holding tank. "Smooth"
hose is used from the bottom of the holding take to the macerator
pump/deck-plate.
My next effort to clear this problem will be Friday, a great way
to start the weekend.

| We replaced all of our plumbing hoses last weekend for the reason
that they were four years old and we just couldn't get the stench
our of them. It was not a job for the meek. LOTS of lemon scented
Lysol, a few dips over the side, and plenty of fortitude. I feel
for you.

A few dips! My God I better get the boat out of Quincy Bay
then, the water outside the boat could be worse than the stuff sitting
in the tank for two weeks :-)
I hope to hold off till its back on land this fall before something
like replacing all the hoses is necessary.

| I have had two pipe blockages on separate boats. The cause was
similiar in each case. I solved it by putting a neat brass plate
with strong wording in the head advising crew/passengers not to place
foreign objects in the head.
Whilst this might not the problem in your case, mine related to female
passengers. Good hunting.

| 941.16 | Temporary Solution | CADSE::MCCARTHY | just call me Mac | Mon Aug 29 1988 06:25 | 13 |
| We finally decieded that the best way to deal with this was to wait
until the boat was on land for the winter and then replace the hoses.
We did drain the tank as much as possible by using one of those
drill-pumps and stuck the suction end down the vent hole of the
holding tank.
I'll let you know if replacing the hoses turns out to be a real
pain in the butt or not.

-< holding tank configurations? >-
--------------------------------------------------------------------------------
My head simply pumps over the side right now, and I'd like to put in a holding
tank. I'm not sure what is the best arrangement?
The Boat US catalog shows an arrangement like this:
Deck
Plate
---
|
Thru +------+ +---------+ | +-------+
hull | PUMP | | Y-VALVE | | | head |
\----| |------|---. .---|-----' | |
+------+ +----|----+ +-------+
| +----------+ |
`--------| bladder |-------'
+----------+
Here's another possible arrangement:
Thru
hull
\----------------------------------.
| |
+------+ +-----|----+ +-------+
| PUMP | | Y | | | head |
| | |Valve >---|------------| |
+------+ +-----|----+ +-------+
| +----------+ |
`-------| bladder |-------'
+----------+
Pump is a manual diaphragm pump, e.g. Whale gusher.
Questions:
Which of these is a better configuration? What other configurations are in use?
How big should the bladder be, for a 29-foot boat, typically with 4 people
aboard? (Boat U.S. has a 16 gallon and a 25 gallon bladder.)
Is a hard tank better than a bladder or vice versa?
In the Boat U.S. config, can I replace the Y-valve with a simple Y pipe?
What does the coast guard look for when checking for compliance with
discharge laws?
Does the bladder vent need a check valve?
What are the merits of having a deck plate (in New England waters)?
Is it better to put two 1 1/2" fittings on the bladder, or a Y off one fitting?
Any recommendations on specific Y-valves to buy or avoid?

-< New head hookups are easy >-
--------------------------------------------------------------------------------
I recently went through this and researched it with a store called
Marine Sanitation who's only business is heads and systems. Their input
is:
Avoid the PAR Y-valve, it clogs a lot.
Avoid a bladder, they leak and are not big enough. Size depends on how
many people you want to service, not boat size. I went with 40 gallons.
Vented loops are necessary if the head is below waterline or the tank
is below waterline.
Keep your run from the head to the tank as short as possible. It
depends on how far your head will pump effectively. Six feet or less is
probably OK with most heads.
Make sure your vent line has no low spots for water to collect.
Good luck. Do it right while you are dealing with new unused parts
because later, it will be unpleasant.

Here is simpler solution without a "Y" valve.
Deck pump out
|
|
|
|
Head------- Tank -------"Tee"-------Inline-----Pump----Thru hull
valve
Arrange the "Tee" so the straight through portion is the most likely
used path. Around Boston the best is to plan on many 3 mile off shore
trips.
I put all the stuff in when new. Not a big problem. Just the hose is
hard to bend and cut. Use double clamps. No leaks allowed here.
