Holding tank electric pump out.

[Impaler]

I ordered with a loo thinking it would be a no tank set up then they told me they had to fit a tank after it was all done. No extra cost so no big deal. I guess that so long as the system is well flushed through it should work fine. CC are pretty thorough.

I’ve ordered a new Cornish Shrimper 21 and it has to be fitted with a tank according to RCD 2 so they tell me. They’re fitting an electric macerator pump together with level indication so I’d be interested to see how well it all works. I asked Cornish Crabbers if they were fitting a bypass so I could, ahem, dump directly to the oggin but apparently that’s against the rules.

Not quite sure what you have written there. Are you saying you cannot discharge into the sea? or you can, but only through the tank? The latter is how gravity tanks are but it is invaluable, if you have the space, to have a bypass for pee and keep the tank for poo. Otherwise you will be in the situation of many we know, having to leave harbours to dump tank contents every two days, which is not always desirable. Or stay where you are and dump it in the dark, not unknown to us.

I can discharge to the sea but it has to go through the tank rather than having an option to bypass the tank which I would do at sea. I’d have preferred this option but rules is rules so they say. Didn’t someone once say that rules are for the obedience of fools and the guidance of wise men? Bader I think.
It’s not a big deal, like most process systems if they are used regularly and flushed and cleaned then they usually work well. I’m sure there’ll be some sort of chemical that you can bung in to keep it all delicious. Don’t want to be like the toad man at Royston Vasey.... “into which we don’t pass solids”. ������

The latest RCD states that

Any toilet fitted in a recreational craft shall be connected solely to a holding tank system or water treatment system.

Recreational craft with installed holding tanks shall be fitted with a standard discharge connection to enable pipes of reception facilities to be connected with the recreational craft discharge pipeline.

In addition, any through-the-hull pipes for human waste shall be fitted with valves which are capable of being secured in the closed position.

So if you need to pee it goes in the tank. Clearly a shot in the foot, as more people will now discharge their tanks in anchorages etc (IMO)

Obviously this only applies to new boats.

Sounds like you need a bucket. I use a bucket at sea anyway, having smacked my head one too many times on the lowish heads coachroof while sailing.

Yep!

Ex-'Comfort' fabric conditioner bottle - the big one with a handle. There's a clue in the name. Brilliant in a seaway or a stumbling journey to the heads in the dead of night.

I hadn't thought of the bypass - when we are staying a while we got into the habit of forward heads seacock shut and aft heads open for pee. But that's rare for us, alas as our boat time is limited so we tend to move on every day, with just odd two nighter.

We're going to fit a holding tank this winter on a Starlight 35. Does anyone use an electric pump to empty their tank at sea? If so, which type? Is it reliable?

I had a holding tank on my Moody 31 which I fitted with a Jabasco macerator. It lasted about 3 years before it needed replacing. The bolts broke. My current vessel has a manual Wale gulper pump. This is much better and takes a few minutes to empty the 89 l tank.

I would not go down the electric route again.

I have had a Jabsco Lite electric toilet on board for something like six years now. It incorporates both a wash pump and macerator/discharge pump. We live aboard for half the year, so the toilet gets above average use. Other than annoying little problems such as leakage from the O-rings on the pump bayonet fittings and occasional accumulations of salts it has been totally reliable. The pump is a centrifugal, rather than a diaphragm type, which maybe improves its reliability, although the water pump is a diaphragm one, exactly the same design as domestic water pumps.

It isn't better because it's manual, it's better because it's a diaphragm pump, not a macerator.

Viv I thing the problem with mine was sporadic use and also the bolts snapped in the cold winter.

Fair point but do they do an electric diaphragm pump for waste?

Yes, Jabsco and Whale both make one. I'm just about to fit an electric Jabsco to mine, in series with the manual one. That's a nice thing about the diaphragm pumps, they can be fitted in series, so if the electric one fails, or you are short of power, you can use the manual one.

Hi, in other contexts there seems to be a lot of praise for the Whale Gulper electric pump, and they do a version adapted for black water. Is this actually better than the offerings from say Jabsco or TMC? I'm asking because I've ditched the chemical loo at last and am just about to install a Lavac. If you buy the electric Lavac it comes with a Jabsco or TMC pump, but in one of the threads last year these came in for some criticism. I'm wondering whether for my installation I should buy the no-pump version of the Lavac and use the Gulper both for flushing and pump out: slightly more expensive, but an area where only the best will do!

I have a Lavac and will be installing a Jabsco electric diaphragm pump. I've fitted them before and never had an issue. Mine will flush the toilet or empty the holding tank, via a Y valve.
