SOG

[goin roamin]

today I received a sog kit to fit. Its the type that goes thru the cassette door there is a micro switch that fits to the underside of the bowl
so that when you flush it starts a fun. to me it does'nt seem to run long enough to do any good. would'nt it be better surely if it ran longer

 

[mitzimad]

no point it running once the blade is shut as it would be sucking against a dead end

I think it’s a non return valve that exits at the bottom of the cassette ,and the exit opening sits on top of the fan unit

Presumably there is a snorkel to reach the air above the liquid.

The micro switch is activated by the movement of the blade and the fan runs all the time the blade is open. The fan is not needed when the blade is closed.

Interesting, thanks. How does it connect to the inside of the cassette to draw the air out?

I have just been out into the cold night air for you.

In the base of the loo where the cassette sits is a foam seal to seal against the base of the cassette.
In the middle of this seal is a plastic section forming a ramp, and as the cassette is slid in, this ramp pushes up a pushrod that opens a valve arrangement in the top of the cassette housing that lets air in from the top down past the pushrod and out the bottom of the cassette.
Below the round foam seal is the charcoal filter and below the filter is a fan to draw the air through and out through the floor of the van.

Our fan continues to run for about 5 minutes from when the button is pushed, but it can be stopped if required.

An heroic adventure in the dead of night to satisfy my curiosity. Thanks.

Mine is the same C400, but without the charcoal filter, the cassette is sealed when is out. As you push it in the compartment, the bump opens the vent tube, so you can vent the compartment and cassette with blade shut. The blade seals cassette to the bathroom, but is not sealed to the compartment.

The charcoal filter from thetford is £24. I am experimenting with activated charcoal filters intended for extracted cat litter trays at less than £1 each. Will let the forum know if they are any good.

On the c200 it draws air from the top of the cassette.
one point many users don't realise if cassette has any amount of waste in what is happening in the tank I always disconnect the hose and put the stopper on as it can flow down the pipe

 

[goin roamin]

I've fitted it and yes it seems a very good idea I just think it should run longer tow minutes after you close the blade,
RS components sell a time delay relay which will delay switch off for up to ten minutes

Mine is this model, vents to compartment when is in.

You can get active charcoal pellets for fish tanks I used then to refill the SOG floor vent filters.

I made use of the Thetford vent to mod my floor vent SOG to a roof vent.

Did you mount the pump directly to the ply board or did you put it on any vibration damping? Did you put any damping under the ply? Now managed to get some soundproofing rubber under the ply, it has made it slightly quieter but not sure it was worth the hours groveling on the floor to do it.

Some of these set-ups sound terribly complicated. Mine has a plastic pipe that plugs into the cassette discharge pipe and exits via a fan( blade operated) assisted chimney through the roof.

Blimey, that all sounds a bit too complicated.

Mines the same, up to the roof

Mines the same, pipe on the discharge screw cap which vents up to the roof, it must be a Carthago thing?

The roof vent is a SOG option but it is more difficult to set up if it is not done as part of the original manufacture. Full marks to Carthago for making it standard. Roof vent avoids need for charcoal filter and avoids puffing smells out where someone else might object.

It’s my first van with a SOG and I’m converted, I’d be hard pushed not to have one now, no need for anything in the cassette and can dump anywhere (officially of course, some dumps as the one at Jim’s can’t dump with chemicals in for example) and no chemical smell in the bathroom
Tried various tabs in the previous moho and some of them was a little overpowering.

On Carthago's the roof vent SOG is an option in the basic pack, but no one buys a Carthago without the basic pack.
