We
just stepped up to a bigger preowned boat that has a VacuFlush system
and are unfamiliar with its care and maintenance. What is the proper procedure?
L.W., via e-mail
As
you’ve already found out, operation of a VacuFlush system is easy
and since the system is under constant pressure until activated, when
you push down on the lever—three seconds as per the manufacturer’s
recommendations—the stored vacuum is released and the bowl is cleared.
Once you release the lever, the vacuum pump continues to recharge the
system. This generally takes about one minute.
The
major problem you’ll probably face is clogging. To avoid this, use
rapidly dissolving toilet paper designed especially for marine septic
systems and always inform guests how the system works.
Should
you get a clog, step on the lever, and you’ll see a small opening
in the flush ball. If the blockage is here, you can either pull it out
or push it through; I’ve used a wire hanger to do this. Once that
hole is open, the clog should go through, as the pump can handle material—plastic
and metal included—up to one-half inch in diameter.
If
water leaks down and out of the bowl, it’s usually caused by debris
caught between the flush ball and the surrounding seal. Cleaning under
this seal will usually solve the problem.
Other
maintenance tips include shutting off the toilet breaker when you leave
the boat and avoiding the use of drain openers, alcohol, and solvents.
Annual maintenance includes changing the in-line vent filter, tightening
all clamps (including the base clamp), checking all wire connections,
and cleaning and tightening the water-valve mounting screws.
There
is a three- to four-year maintenance cycle for the vacuum pump, depending
on the frequency of use—weekend outings compared to long-distance
cruises. Contact a SeaLand dealer for this service. Visit www.sealandtechnologies.com
to locate one.
What
is the recommended procedure for prepping my boat’s previously coated
fiberglass bottom? K.T., via e-mail
Bottom
painting is 90 percent preparation and 10 percent application. The area
to be painted must be clean and free of grease, dirt, or any other contaminant
that can lead to coating failure.
A
thorough powerwashing is a good way to start. After letting the bottom
dry, inspect the entire surface for loose or flaking areas, grease spots,
and blisters, which must be repaired before painting. If the surface is
in good shape—no cracking, peeling, or flaking—sand it with
80-grit paper, which will not only prepare the surface for new paint,
but also remove any residual contaminants.
Wipe
down the bottom using clean rags moistened with the appropriate thinner.
If you are using a new paint system, test a small area to make sure the
paint is compatible with what’s already on your boat. Finally, carefully
follow the manufacturer’s recommendations for applying the kind
of paint you are using.
