TWL: Macerator Pump Location
This week I am plumbing our holding tanks.
Question for y'all. Where is your macerator pump located? Is it below your
holding tank so that it collects the worst of it but is primed and ready to
go or, is it above your holding tank which means that the contents dries out
inside?
How about your Y valve...same question. It used to be that Y valves were
above the tank because they were on the intake side of the tank. You would
switch whether you wanted to pump into the tank or out a thru-hull from your
head. Now of course, they are on the discharge side of the tank to pump out
or pump overboard.
I am tempted to put them both above the tank (my pump will self-prime) and
try to rinse the system after macerating. Mistake?
Thanks in advance.

Eric,
My macerator pump is located immediately above the top of the holding tank.
Mounted vertically, that is straight up and down. REAL GOOD REASON for this
placement.
WHEN it quits you will have a full load in the tank, Murphy, you know him
well.
Anyhow , since it is higher , just barely, but that is like being just barely
pregnant, I digress, you are able to remove it for repair or replacement without
spilling the contents of the tank!!!
My experience , your gain!!!

Mea culpa, mea culpa , mea maxima culpa,
All of you Roman Catholics, over 50, remember that !
You see I have a new laptop and I am just not adept with it and failed to SNIP and
will catch you know what for that. So I must make amends by sending another e mail
saying I am sorry. But that uses more band width !!!!!

....Where is your macerator pump located?
Aboard the Queen, the pump is mounted at a level near the base of the tank.
The head feeds into the tank directly. Tank output leads to a Y-valve,
which selects either macerator thru-hull discharge or dockside pumpout.
Y-valve, macerator, and hose junctions are all located within about 15
inches of the tank.

Question for y'all. Where is your macerator pump located?
I replaced a blown holding tank last winter. The old tank abandoned and a
new tank in a new position installed and plumbed to the two heads.
Macerator is installed on top of the tank above the highest posssible fluid,
and the tank is installed at an angle so there is a very small area 'low'
point and a small area 'high' point. As the old tank failed because of a
vent plug (yes I should have checked it), the new tank has extra large vent
and very short vent pipe. Each head connection (unfortunately have to pump
uphill to tank so the input lines can drain downhill) is on a 'T'
connection, with a full dia valve on the down side of the top of the 'T' to
facilitate cleanout with a wire pipe brush when it becomes necessary. The
valve allows a bucket to go under and all the contents from the top of the
pipe rise to go into the bucket, under control.
Tank flush is just point some shore water at the vent hole....
Also, I installed the pump-out fitting in the hull side. This is because
some shore pump-outs are not well maintained with low lift, and so that any
drip is out-board. I am quite happy with this so far.
The only down side so far is that I left the heads as salt water fill, and
because of the up hill pump, lots of water is required. Still looking for a
good solution here. Fresh water is good but with only 250gals .....
Luv your boat...
