Saniflo Sani Access Pump

[DBA Forum (B) - Lorna Baker]

Hi,

We are planning to get rid of our smelly grey tank and replace it with something like the Sani Access Pump (http://www.saniflo.co.uk/homeowners/sfa-product-line/saniaccess-pump-product-description/) which is essentially a Saniflo, but with maintenance access from the top, in situ.

Can anyone who has a Saniflo advise on what fittings can be used to attach existing outlet hoses?
All of our waste is plastic compression 40mm waste pipe, except for one, which is a 32mm hose. This one will need to be somehow t'ed into one of the other pipes.

Also, if the unit was to fail, is there some way of attaching another pump to remove the excess water already in the pipes, apart from the usual pile of towels - the unit will be sitting in the bottom of the boat (it's the only way we can get enough drop).

Thanks
Lorna

Lorna,

I've had a Saniflo for years, and I'm a big fan of it.

Mine is connected directly to the back of a conventional domestic
toilet, and sits under the (conventional) cistern. No problem with
room for it. If you are using a toilet that empties through the
floor, perhaps you might consider replacing it? Then you wouldn't
need to put the Saniflo "in the bottom of the boat". Toilets are not
expensive, even low-volume flush ones (or dual volume flush ones like
mine).

I don't understand your comment about drop. My Saniflo sits on the
same floor as the toilet.

The supplier I used is:

http://www.h-i-e.co.uk/Saniflo-Waste-Macerator.html

Excellent service (especially speedy delivery). And compare the
prices.

The connections to my Saniflo are the large entry (which connects to
the toilet via a rubber bellows which came with the Saniflo), and a
simple (if large) jubilee clip. The exit is a 25 mm (IIRC)
semi-flexible hose, attached to the Saniflo exit elbow (on top of the
unit; it unplugs) again with a jubilee clip. This hose is much easier
to route to the waste tank than the larger rigid pipe you describe,
but it is much the best for there to be no fittings at all in it
between the Saniflo and the tank to avoid clogs (mine has one join
along the way which trapped a plum stone once with very messy
consequences in the washroom). There is a non-return flap in the
Saniflo exit fitting so that there is no need to get rid of the water
in the exit pipe when it is disconnected (should the Saniflo need to
be removed for service).

And I certainly would rather disconnect the Saniflo and take it
outside before opening it for servicing than do it in place!

Hi Adrian,
The Sani Access Pump is only for grey water, not the loo, hence my 'drop' comment - it needs to sit below the waste pipes from the basin, bidet, bath and shower.
At the moment the grey tank is below the bathroom floor, so allows for a reasonable pipe fall.
Thanks
Lorna

Lorna,

Made my own grey water tanks.
Big plastic box with lid - approx 50 ltr 40 and 32mm pipe glands
Jabsco hydro air switch
24v Whale gulper pump.
Bath overfill alarm

www.luxe-motor-kei.co.uk/internal/page/image83.html

Tanks sit in bilges - 1 aft for shower, basin and washing machine. 1 fwd for 3 basins. Bath has its own dedicated whale gulper.

No smells or floods in 10 years.

Can't see why Saniflow should not work.

Balliol,

I have not as yet encountered a reliable switch, whether float, electronic probe or whatever.

I have had no issues with the Jabsco Hydro Air pump switch. As a precaution though, I do blow through the air pressure tube - lung power - as part of my first of the month checks. This blows out any gunge that might have accumulated in the "diving bell".

We now use Whale Gulper pumps for our showers, plumbed directly to each shower and switched manually when the shower is in use, which is not a problem to us. They are very quiet : you have to put your foot over the trap to reassure yourself that it is working. One big advantage is that you can locate the pump somewhere convenient for maintenance if needed. In practice the pumps seem to last very well, and need no filters (to block) or automatic switches.

For the other wastes I suspect that the bidet and bath would fall to a sole-mounted tank if that were easier, as of course would the basin. My inclination there would be to feed these to a sump, (perhaps purpose made since the proprietary ones are all pretty useless) and again use a separate, easily accessible Gulper pump. You would want to fit an auto switch of some sort in the sump, and that would be the weak link since I have not as yet encountered a reliable switch, whether float, electronic probe or whatever. If the Gulper is also wired to be switched directly (manually) then you are covered at least temporarily if the float switch fails. Our galley sinks go to a similar arrangement and occasionally the float jams, which usually just requires the sump to be given a shake, but actually
it last failed some weeks ago and I have not got round to it. The manual switch is easy enough.

My reasoning for all this is that whilst Saniflo type macerators seem pretty good, and are possibly and in some circumstances the better choice for black water rather than marine macerator toilets, they can be awkward to work on due to location, and can overflow if they fail and that is not detected, resulting in smelly soapy bilges.

Balliol.

Hi Balliol,
The sump you mention is exactly what we have, with a Whale Gulper.
All our grey water goes into it - kitchen and bathroom.
Hence, the tank gets gunged up and the Hydro Air switch stops working, so the tank needs cleaning every couple of weeks.
The Sani Access Pump looks good, but can't be isolated, should there be a failure.
The lid comes off for maintenance, but it would need headroom, as you say.

Hi Colin,
We already have the same sort of set up as you.
Our tank is bigger than it needs to be, about 50 litres.
It smells and needs washing out regularly (the baffles preclude doing a great job of this).
We want to replace it with something that doesn't let the contents sit for long enough for it to smell, and that isn't noisy enough to wake us (bedroom is next door) when it pumps in the night.
The Sani Access Pump looks to be just the thing, but we aren't sure about connections without seeing one and would like to plan things before buying.
