Q1: Are they any good for removing the pong when the "slice" on the cassette is open?

 

A1: YES - that's exactly what a SOG system does well.

 

Q2: Are they really worth the approx 110 quid that they cost?

 

A2: Difficult to quantify value-for money. I wouldn't want to go back to using toilet chemicals, and I very definitely would want a SOG ventilating system if I were not using toilet chemicals.

 

Some light reading... http://tinyurl.com/bph35o6

 

Thanks for giving your thoughts on both questions. I prefer to use SOG system and even recommend it to others.

It's a peculiar (and little known) fact that people in Atlanta Georgia who have septic tanks are also avid readers of the Out&AboutLive motorhome forums. The reason for this is not easily understood and forum members are invited to suggest why this should be.

 

Now that's an interesting statistic

Wikipedia tells us that 25% of the people of North America use a septic tank.

 

I wonder how many people; worldwide would consider using a SOG system in a domestic situation?

 

I think I'll stick with "organic" chemicals,

I'll reply to my own post; .........About as many people who would consider installing and using a composting toilet. Not very many!

Many thanks for all replies.

 

We've now decided to go ahead and buy, and then I'll fit, a SOG system for our Thetford C200 toilet.

 

But we'll wait to purchase it until we are up in France again, in mid-April to buy it........as the cheapest UK price I can find is via ebay, and it's 110 squids plus 20 quid to post it to us here in Spain.

Although Narbonne Accessories shops in France sell them for about 140 euros if/when I visit one, they also want 25 euros on top as their minimum parcel postage charge to Spain.

 

You'll regret it.

I can remember a tv program in which an inventor had a extractor input fitted near to the top of the bowl which extracted the odours and that was way before the SOG was available.

 

 

Seen them on German domestic loos years ago.

I can't recall his name, but I think the inventor you have in mind was a big bearded eccentric guy who often appeared on UK TV 'science' programmes. I vividly remember him rowing a dinghy facing towards the bow.

 

The 'ventilated toilet-bowl' idea seems to have been invented regularly. For example

You will regret, delaying buying, buying or what (?)

I don't think in other countries it is preferred.

It is becoming more or less a standard fitting on European vans. No SOG means when you open the trap the disgusting content is vented into your living space, not to the outside. so no matter what cancerous chemicals you use to disguise this, its in the van.......and that some of you Luddites don't get it and prefer to pour more noxious chemicals into the environment and waterways? mind boggling......

Hi Judge,

Maybe it's a standard fitting because that puts more money into the manufacturer's pocket that would otherwise be spent after the van had left the showroom?

I can see the attraction of venting the "holding tank" to air, outside the van, and the idea of venting to roof level makes sense.

I have not used noxious chemicals in 3 years of van ownership, and I've always emptied our holding tank into a designated drain; on a site. In that time I should imagine that 99% of the time it has only contained urine. That's how we use our van.

Having only used the holding tank for faecal material on maybe 4 occasions, whilst using a "biological" chemical, and having seen the limited degree of "breakdown" achieved over a period of maybe only 36 hours, I found the emptying process unpleasant.(I don't think a SOG system works any better over such relatively short periods.)It's not something I would choose to do on a daily basis. Not a holiday activity in my book.

Calling people Luddites doesn't advance your argument either.

Regards

Just a quickie guys 'n gals.........

 

As mentioned earlier, I'm definitely going to buy a SOG system for our Thetfrod C 200 toilet whilst in France when we are up there from next week for a month.

They are significantly cheaper there than I can find, or get delivered to, us here in Spain.

 

I'm going to fit it whilst we up there on tour. I'm a good DIY'er, and from what I've seen on the internet, they look very easy to self-fit.

 

The only piece of technical info I can't find out is: what is the diameter of the hole that I need to drill through the toilet cassette door?

 

I've got several different sized hole-drill tools at home, but I don't want to lug around in the MH any more DIY kit than I need to.

 

If anyone could tell me, I'd be very grateful.

just had a look but hard to tell as all boxed in and dont really fancy stripping it down.....Do you have a reamer in your toll box? I would think a 20 -25mm hole should do it and just have a reamer or file as back up. someone may be along who has DIY fitted..

 

EDIT: Ah! forget it! :D

I'm an absolutely brilliant DIYer and I suggest you don't try to fit your SOG system until you get back home.

 

These are the installation instructions relevant to your Thetford C-200 model of toilet:

 

http://www.sognz.co.nz/thetford-c200-installation-instructions/

 

As has already been advised, the recommended hole diameter is 36mm-37mm but, when I fitted a SOG to my Hobby's C-200, I didn't find a suitable size in either of my two hole-saw sets and, if you drill an oversize hole, the screws that hold the fan-unit to the door will have nothing to bite into. I vaguely remember drilling sample holes in a piece of plywood, trying the ventilator fan-unit in those holes to see which would be closest to the diameter required and then (as JudgeMental suggests) opening up the hole to provide an optimum fit.

 

I also suggest you remove the locker-door rather than drill the hole with the door in-situ and be prepared to extend the cabling supplied with the kit.

 

In principle, fitting a SOG kit to a C-200 is straightforward: in practice, there's plenty of opportunity for a serious cock-up - for example, if you modify the 'saddle bracket' wrongly.

 

(I have a Practical Motorhome 2005 article about fitting a SOG kit to a Thetford C-200. The then UK distributor for SOG kits used to provide buyers with a copy of that article as he did not particularly rate SOG's own installation instructions. If you PM me and let me have an e-mail address I should be able to send you a scanned copy of the Practical Motorhome piece.)

Our new Auto-Trail appears to have a SOG system built into the Thetford Toilet when you press the flush button an extractor fan cuts in and draws the air from the toilet through a filter system and after a short while the fan stops  , but if the fan is not required when you flush there is a touch screen button next to the flush button to stop the fan running.

Its odd you should say this, because on my most recent trips abroad I've noticed less and less m?h's with SOGS fitted and these include the usuals, Cloggies, Froggies, Swedes, Germans etc. The reason we avoid parking next to a van thats got one fitted.....which thinking about, could that be the reason, yourself has one??

Like I said earlier...7 year and 2 vans, both having one (ordered by choice), and only smell is when emptying. Are you sure your not smelling a waste tank, as this far more likely if it is that strong IMO

 

We thought of changing the van recently and all we looked at included a SOG as standard....that was what my comments based on. From Kellys comments above its pretty clear his factory ordered autotrail came with one.....

Hi Kelvyn;

and do you use it as a SOG? or do you use a chemical of some sort and simply use it as a holding tank venting device?
