Service guy is wrong...he either isn't a "certified VacuFlush tech," or
he didn't pay much attention in class...'cuz a VacuFlush should not
cycle between flushes at all, even for weeks.
First step: consult your owners manual...it includes every possible
symptom, probablea causes and cure that a V/Flush can develop. That
said, however, I suspect that you haven't been putting anywhere near
enough water through it, resulting in a bit of waste or TP caught in a
duckbill valve that's preventing it from closing completely...and
therefore creating a slight air leak. If I'm right, the fix is simple:
fill the bowl with water and flush it. Or, there may be a bit of waste
stuck to the seal in the hole in the bowl that's preventing the dome
from sealing it completely (you can rule that one out if the bowl holds
water). If that doesn't cure the problem, or cleaning the hole in the
bowl doesn't work, you have a warranty claim...call SeaLand.
However, for future reference you need to know that SeaLand's claim that
the V/Flush can use "as little as" 1 pint of flush water is VERY
carefully worded. If only urine is flushed...no water added to the bowl
first, no TP either...then yes, you CAN get away with that little, at
least for a few flushes. But if you do much of that, unless you want
odor, at least once a day you need to run at least half a bowl of clean
water through it to rinse out the system. It's also advisable to add at
least half a bowl of water ahead of solids or any TP (iow, every time a
female uses the toilet)...that's a quart or more. It's also essential to
leave the pedal down for at least 7-10 seconds after the bowl is empty
to rinse out the pump and duckbills--to prevent a buildup in the pump or
bits of waste or TP from becoming stuck in a duckbill, creating one of
those pesky air leaks that causes the pump to cycle for no reason...at
least another quart. And if you don't want permeated hoses, it's a very
good idea--last thing before the boat will sit (or at least once a week
if you're living aboard)--to fill the bowl to the rim with clean water
and flush it through to thoroughly rinse out the vacuum tank, hoses and
pump...'cuz suction splatters waste all over 'em and the flush water
flow isn't sufficient to completely fill the hoses. So if you're not
using enough water to keep the system rinsed out, you're just asking for
problems.
The other common error that many V/Flush owners make is easing the pedal
up instead of just letting it go. It's spring loaded for a reason--to
allow the dome to snap back into place with enough force to seat and
seal the hold in the bowl...easing the pedal up can prevent it from
sealing...and over time will prevent it from doing so permanently. So
just let it go...that's how it was designed to work.
Btw...I had V/Flush toilets on my last two boats and was also a dealer
for nearly 10 years...so I'm INTIMATELY acquainted with 'em...what keeps
'em working trouble-free and what doesn't.
