Re: Is this a windup?
They normally work by emptying them. Howver, advanced design have essentially limitless capacity created by making such a goawful pong that few if any crew use them (eg me) and hence they will lasty for ages. I advise that you sell the boat immediately, and stay 50 yards clear of it during the sales process.

Errrr. How long have you had the boat and only just discovered the holding tank? I assume it's pretty full by now? Or backing up?

No wind up. Do I need to put chemicals in the wretched thing?

I've had it from new for 3 years! Think its been switched to empty mode ever since I bought it.

By a combination of valves depending on your set up.
Correct Position 1:
Pump out direct to sea
Correct Position 2:
Pump out to holding tank
Correct Position 3:
Pump out holding tank to sea
Usual Position:
Fill up holding tank until contents flow from vent down outside of hull, or if you are really unlucky, vent blocks, you blow out inspection hatch and empty tank into bilges!

Hm. Well, I would blast a load of chemicals all over. Then shut the seacock, clamp all the pipes, take off pipes from bog and seacock, unscrew the whole 2way valve and htank assy and run ashore to somewhere where nobody wil recognise me. Replace the existing pipe with a new one. Announce newly pleasant-smelling boat to swmbo. Not sure what to do with holding tank, probably tip it but not sure where!
Foruntaley i have had a complete medical in the last week and have not contacted cholera. Probably totally immune by now anyway. So, thanks for that.

Re: No!
Um, you do need to put chemicals in it, but it's a bit late for that.
You need a nose clip, rubber gloves, make some pipe clamps from dexion and nuts and bolts, and getta a new piece of pipe. Isolate the thing, remove, clean the place up, replace pipe direct to seacock, and then apply 1 gallon of domestos, everywhere, followed by some more domestos.

I worked at Porton Down for a while in Category A containment suites. For a very substantial sum, I'd undertake decontaminating. Fixed cost plus expenses including new NBC suit, nose plugs, several mask filters, and decon shower. I'm probably more equipped for this hazardous mission than most, but it will cost you dearly!

In case you wanted a serious answer!
Switch diverter valve from overboard to holding tank
Use as normal, as many times as tank capacity allows
When offshore open outlet valve from tank and pump out. Close valve and pump seawater through loo several times to part fill tank. Leave a while (boat movement helps) then pump out.
Alternatively head for nearest pumpout station (good luck finding one) and they will extract contents via deck outlet (should be one fitted).
You may need to trace the pipework/valve systems through to see how your particular system is set up, there are multiple options. We had to do this and then labelled up the various valves etc so we know which does what or vice versa.
We have never found any need for chemicals and have no smells, though when we were looking at boats for sale found more than a few stinkers.

Sound of hysterical, babbling laughter!!!
Oh, and don't smoke within 50 metres of it.
Seriously though folks, if it's a standard Sunsail style fitment (like your cruisy chute) somewhere beneath it there will be a valve that opens it to the sea. Get a mile or two offshore and downwind of any major population centres, open the valve for a minute or so (there may well be gurgly noises associated with this - it used to be a specatator sport for the kids when we were sunsailing - they would cling to the backstay while daddy went below to open the turd tank and then make loud delighted "yuk' noises as we sailed away from the brown cloud). Close the valve. Pump the loo energetically for a while to refill the tank with seawater. Sail around for a bit, preferably in a bouncy bit of sea, to shake everything up. Repeat valve-opening exercise. Continue until water exiting tank is as sweet as a vicar's maiden aunt's farts.
Yachtmaster eh? Didn't they teach you nuffink useful!

It would be eminently sensible to empty the tank whilst sailing upwind!

We have a "built in" glass fibre tank which holds about fifty gallons. Every drop of foul/grey water goes into the tank. There is a 2" vent pipe which only poses a problem when the tank is more than half full and we are down wind of the pipe outlet.
You can buy a filter to go on the vent pipe to kill the odour, but we find that a bottle or two of Domestos down the galley sink and heads basin keeps everything quite pleasant.
Been in use for four years and we discharge via an electric diaphragm pump when out at sea. If forced to empty when on a mooring, we only partly empty it and don't feel too bad about it as at least the discharge is very very small with no fears of dead soldiers floating past.

Re: PS
I was thinking of going out to watch the RTI on saturday, do yo think that between the Forts would be a good place to empty the weapon of mass destruction? Seriously though I think I'll go for the option of trying to get it clean in situ before going for TCM's radical removal project .. I''m a coward!!

Re: PS
I haven't heard of a holding tank system system which has three discharge arrangements. Usually just one or two:
1. Toilet discharges to holding tank. Holding tank discharges through underwater hull fitting and is pumped out as necessary (best to do it frequently - i.e. whenever "at sea"). There is no need to treat the holding tank with chemicals. I have this system and it works perfectly well. There is a hydrogen sulphide smell which is noticeable when the toilet is first used after having been left for a while but this disappears after the first use with a bit of seawater pumped through the system.
2. Toilet discharges to holding tank. Holding tank discharges through underwater hull fitting OR through Y connection and diverter valve, through deck fitting (needs a pump out facility).
I suppose it's possible to have a third arrangement (instead of or as well as number 2) where there is an option for the toilet to discharge directly through an underwater hull fitting instead of via holding tank but I can't quite see the point of it. Means a need for at least one more pump and possibly an extra skin fitting.
I'd have thought it's less likely that you have number 2 arrangement. It's essential for a boat which is used on inland waters but not otherwise. In the case of river boats, there is sometimes no underwater discharge (Nick2's arrangement) or, if there is, it has to be sealed off so it can't be used.
Do you have a deck pump out fitting? If not do you have a diverter valve which is set either for discharge to holding tank or underwater? I suppose if you have mostly used direct discharge and then it was switched to holding tank you may be getting an accumulation of gas in the holding tank from waste which has been sitting in it a long time. In that case I would suggest you empty it at next opportunity, then flush it through a few times with plenty of seawater and some ordinary domestic bleach.

Confessional
One of the most hilarious stories for a looooong time - Kim, tell the YM editor that the next Confessional story has written itself....... and probably has nautical mileage for several follow-up stories - or should that be follow-through?
