The Cricket is good toilet...but is a "light duty" toilet. For long term
reliability and durability, and especially for serious cruising, the PH
II is a better choice...it's been rated the best manual toilet under
$500 for several decades. If the PH II won't fit in the space, Raritan
now offers the PHC, which is the same pump but on the same base as their
Compact II and costs a little less.

We've gone through this before in this newsgroup - the PH-II is a
poorly designed plastic toilet - that squirts liquid sewage out
through the "water lubricated" top seal - into your face when you bend
over to flush it. Do a google newsgroup search in the archives of the
RBC newsgroup for the problems with the crappy PH-II toilets. Peggy
forgets to say she sold her co. to Raritan and then worked for them -
so her recommendations have a taint or bias to them - but why's she's
biased to the crappy PH-II is beyond us.

If I am biased, so is the entire industry...because the PH II and its
predecessor the PHH have consistently been rated the best manual toilet
under $500 for more than two decades.

But let's talk your own bias... I have nearly 20 years of experience
with literally thousands of owners of just about every toilet ever made,
including a few you've prob'ly never even heard of. How much experience
do you have that would make your bias more valid than any I might have?

We got one a few years back and like it, but it is a bit different than

Yep...instead of the piston/cylinder pump sitting beside the bowl, the

It's not really a rebuild kit, it's a whole new pump except for the
housing. Unlike piston/cylinder pumps, the Cricket doesn't have any
seals, o-rings, gaskets etc--the parts in the usual "rebuild kit"...so
it doesn't require "rebuilding" in the usual sense. In fact, it doesn't
even need lubrication. A kit is needed only as often as any other toilet
would need a whole new pump assembly. So the price for it should really
be compared to the prices of a new pump assemblies for other toilets,
not rebuild kits.

I that case, you need to use the lee rail less, use the head more. Your
guests will appreciate it. 'Cuz it's definitely true that lack of use is
harder on anything than constant use.

Oh! I didn't know that. That makes me feel better. It's simplicity was a
primary draw. I had gotten tired of lubing and rebuilding every
couple-three years. Guess I should get that kit and vacuum pack it.

It sure seems to have trouble less often, though it took a while to
learn to take long, slow, full-length strokes every time.

If only the wet/dry switch weren't in such an inconvenient location.

What is your opinion of the cricket? we are looking at replacing the
head in Windwalker when we add a holding tank, and want something
sturdy, reliable, and not too expensive (I know, pick two of the
three...)

The Cricket is a nice toilet...but not without quirks. For about the
same price, the PH II will give you 3 for 3.

I have a plane to catch and don't know if I'll have NG access for next
week. So if you have more questions, hold 'em...I'll answer 'em when I
get home.

I bought a cricket head, based largely on advice from this ng. My
experience with it is mixed. It is slightly better then the
piston-pump W-C it replaced. I think after having owned it, I can
make some observations.

The first problem I had was that the first generation (which I bought)
came without a piece that they have now. This little ring keeps the
poo from blowing back in your face when too much pressure builds up
pumping a big load out. This went on for about two years and really
soured me on the cricket. I found out from this ng that raritan would
send me this blow back stopper part for free, and since then, I
haven't had poo blow back into my face. Good thing I check ng's once
in a while.

At about the same time it started to leak so when I got the part I
also ordered a rebuild kit. Turns out nothing was wrong with any of
the rubber bits - but the pump base itself had cracked. Which brings
me to the next problem I have with crickets - they are all plastic
construction. I'm sure this is what keeps the cost down compared to
say groccos or skippers or other diaphragm pump based toilets made of
bronze. Anyway, I fixed it with some west system, rebuilt it, and the
thing finally gave me about 3 years of pretty maintenance free
operation, no leaks, no poo blow back, rarely clogging. Those three
years of good live-aboard use make it worth the low price in my mind
and have softened the hard feelings I had about it during the years of
poo blow back and leaking.

Now I just recently moved ashore. My toilet sat dry for about a
month. Last week I went to go sail out to the islands here and the
head wouldn't flush. I couldn't figure out what was wrong and instead
of going sailing I spent the whole morning thurs. taking it apart, and
handling feces. While I took it apart a stainless bolt that rests in
a bronze thread molded into the plastic had siezed and while I torqued
on it the plastic broke. Well that was it. I went sailing with a
bucket and when I got back, I went to defender's website and ordered a
lavac.

I'm not saying the cricket's a bad head. You get what you pay for,
its pretty good for its price (with the blow back stopper that now
comes standard). I actually chose it because I have a small space and
it is very compact compared to other heads that aren't the piston
types. I won't even consider the piston types - what an absurd
design. If raritan came out with a bronze version or the grocco was
smaller I'd go with those. Meanwhile, I know the lavac will fit and
the rebuild kit for its pump can double as the rebuild kit for my
cockpit manual bilge pump.

Raritan offers an "extension pole" that allows it to be operated without
sticking your head in the bowl.

The REAL problem with the Cricket is actually an "operator error,"
common among owners of most toilets, but the Cricket is much less
forgiving: incomplete flushing...ceasing to pump as soon as the bowl is
empty. In most toilets, that only leaves waste and/or TP sitting in the
discharge hose where it rarely creates a clog unless someone flushes
something they shouldn't have. But because the Cricket's pump is just a
large diaphragm directly below the bowl, unless the use continues to
pump till all the waste is pushed out the discharge on the side of the
pump, waste and TP build up in it, blocking the discharge, till it
produces the backpressure and eruption you describe. After numerous
attempts to design a flapper valve strong enough to resist the pressure
needed to break up the clog and send it downstream, Raritan--also
knowing that few if any boat owners will flush enough to keep waste from
building up in it--finally gave up and discontinued production of the
Cricket this year.

Composting toilets also need power 24/7, Karin, to run the blower and
evaporator. Also a means of draining off liquids that exceed what can be
evaporated, which in coastal waters means some kind of container for
'em...'cuz they can't legally be drained overboard. Composter are an
alternative worth considering on a large powerboat on inland "no

coastal waters.

Peggy,
Have you ever heard of the following setup:

The waste tank is ABOVE the water line with a bottom drain to a seacock.
There is a second drain from the top of the tank to the deck pumpout.
The head pumps up to the top of the tank.
Close the seacock in protected water to keep the bad stuff aboard and then
open the seacock when you get out.When offshore, simply leave the seacock
open to drain as you go (so to speak).

Real simple if you have the freeboard.
I wouldn't worry about carrying the weight so high because the tank would
always be empty out to sea.

I'm not crazy about that set up. When the seacock is closed waste has to
sit in the line to thru-hull, permeating the hose...any sludge in the
tank will end up in that hose, so if you're in coastal waters very long,
that can cause problems...and I can't see any reason to go through a
tank at sea instead of flushing directly overboard. If the tank vent
should become blocked, you'll have problems flushing the toilet due to
the backpressure. Worst case would be a blocked tank vent AND a clogged
overboard discharge hose at sea in 8'+.

That is _nearly_ exactly the set-up that I have, with one important
modification, see after Peggie's comment.

Right. So what I did is to have a PVC ball valve right at the drain,
then go with sanitation hose (the good one, of course) to the
seacock. Both the PVC ball valve and the seacock are usually closed
and only open off-shore for draining the tank. Thus, the hose ONLY
ever contains sea water (or antifreeze, in winter), except for brief
periods during draining. And after draining the tank I would pump
enough sea water through it (using the existing pump, i.e. through the
head) to make sure it is clean before closing both valves again. Just
like you pump fresh water into the tank when pumping it out.

Of course, I have never done it so far since I was always within 3
miles.

...and I can't see any reason to go
through a tank at sea instead of flushing directly overboard.


Oh, reason is options, and simplicity. I can sail legally in coastal
waters and without problems off-shore. True, having some construction
with Y-valves, or additional pumps and dip tubes would also work (and
actually have some advantages), but this setup is far simpler.

If the
tank vent should become blocked, you'll have problems flushing the
toilet due to the backpressure. Worst case would be a blocked tank
vent AND a clogged overboard discharge hose at sea in 8'+.

OK, this part I don't understand. Why would a second drain block the
vent(s)??

"Options?" What options? It offers none...all the waste has to go
through the tank, no way to bypass it. It also means that waste has to
go uphill to the tank, leaving the head discharge hose full of standing
waste. So you have two hoses begging to become permeated. And in your
case, a ball valve that prob'ly won't work because you don't sail
outside 3 miles often enough to keep it from seizing.

A pump in one of the tank discharge lines, a y-valve in the head
discharge line...not much more complicated, and now you have options.

vent(s)??


It wouldn't...one has nothing whatever to do with the other. But Murphy
was an optimist who prob'ly based his law on the typical boat owner's
approach to marine sanitation system maintenance. Tank vents,
especially on sailboats due to waste running out them when heeled, are
highly prone to clogging if owners don't backflush 'em regularly--which
few do (and when the tank pressurizes, it's last thing owners think
of...they think it's due to a clog in the discharge line, often with
disastrous results). Nor do many owners ever flush out their tanks to
eliminate sludge buildup. Worst case would be a blockage in both lines
occurring simultaneously...no escape for displaced air in either
direction--out the vent or down the discharge.

Peggy -- I think SunMar makes one that doesn't need any power, but they do
require that "excess fluid drainage" that you mention. Some of those that
require power claim to be able to dry the "fluid" sufficiently not to
actually use the overflow under lower usage (one or two people full-time),
but they're also way too big for my boat.

Composting toilets also need power 24/7, Karin, to run the blower and
evaporator. Also a means of draining off liquids that exceed what can be
evaporated, which in coastal waters means some kind of container for
'em...'cuz they can't legally be drained overboard. Composter are an
alternative worth considering on a large powerboat on inland "no
discharge" waters, but IMO are totally impractical on any boat in
coastal waters.
