My name is Jimi and I have a holding tank

[jimi]

How do these things work?

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.

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!

..or you could just ask Haydn for advice?
