I’m with Brian on this. F40’s have a head intake line on the
starboard side (head on port). When you’re heeled to port, water
WILL flow to the bowl unless you have a loop above wherever the
water line may happen to be, but I don’t see the point in “letting”
the shower sump pump do the work.
I put a Lavac head in my F40 There’s a little “button” in the inlet
line with a tiny hole that serves as a vacuum breaker. All the loop
you “need” is enough to get it above the bowl water level at any
point of sail.
It’s MUCH better to close the head inlet seacock. If this is “too
much hassle”, then put a 1/4 turn ball valve on the line just before
the head. That way you can open it to flush, and close it to pump
the bowl dry, regardless of what type of head you have or the
condition of the valves. Water won’t siphon in, even with NO valves
in the head (like the Lavac)
As far as not closing the seacocks while you’re off the boat…
Unless you have a center cockpit boat with cockpit drains that go
thru seacocks below the water line…CLOSE them all. Not only does
it “exercise” the seacock (increasing intervals between servicing),
it’s REAL hard for an oyster to block the barrel opening if it’s
only open when you’re using the boat (unless you live on it). If you
close them every time you leave the boat, you can pretty well rest
assured they are gonna work when you NEED to close one while USING
the boat.
A little pickling vinegar in the sink drains after closing the
seacock will keep the stink down. I take a gallon of it with me
every time I go to the boat, and flush what’s left (after using it
for cleaning) down the head and overboard (after closing the inlet
seacock) before I leave. It only costs about $2 a gallon, and this
keeps the discharge lines a LOT free of the “concrete” that builds
up in them otherwise.
The guy who lost his engine to the “well meaning” samaritan would
have probably been ok if he’d put a sign on the breaker panel
(hanging over the ignition breaker) that says “ENGINE SEACOCK IS
CLOSED”. If you really want to be anal about it, leave the
floorboards open above the cooling water seacock and hang another
sign on that seacock to make sure anyone can find it (then hope
nobody stumbles into the bilge in the dark).
Some things are just common sense…like putting the keys in your
pocket before you get under the truck to change the oil.

Fellow head
cases,
I am presently
re configing the entire forward head system on our F45. The intake has no loop at present, but
the discharge does. I will be
disabling the discharge loop. Flushing will always be to the new holding tank. It will have a very heavy
duty pump that is all downhill from the tank. Threaded dipsticks in
tank for all three ports. 5/8 vent line that is
all uphill. New tank is mounted athwart ships on the bulkhead under the
vberth. Fabricated
some carbon fiber pieces for securing it. Holds 19 gallons as
opposed to the puny 11 that the hold tank held.
Am hoping to do
a vacuflush on next years budget.
In the past we have had occasional siphon on the intake in severe
heeling. So, I agree with the view
of those who favor closing the intake thru valve. Adding a loop for that just adds more “Murphy”
stuff.
Am moving the
deck pumpout forward to the port side bow area. This will shorten that by about 10 feet
of hose and be all uphill, no dips.
Have no inline
connectors. All hose is direct to a
fitting on the tank or the thru hull.
On different
topic, I intend to install a ball valve on the diesel fuel tank vent.
52 degrees today
in Newport. Launch in 3
weeks.

I redid my F-33 with a vacuflush and 22 gallon sealand spec (thick walls) tank
and sealand sanitation hose. Very happy with it. Uses little water to flush so
lots of capacity and basically odorless and clean.

I am planning to install discharge waste pump that will go from
holding tank to a 1 1/2" discharge thru-hull. Does anyone have any
recommendations for a good make/model for a discharge pump for this
type of service?
Thanks.

Sealand T12 Waste pump. $280+ west Marine. One available on Ebay
right now for $70. Bellows style pump. Indestructible, easily
maintained, will run dry forever. Two one way duckbill valves (last
2-3 years before replacement) prevent backflow through pump. Beats a
macerator style pump all to hell.
