In case you haven't seen the vid, very quickly using a pressure pump to pump water when the pressure drops, so it works like a normal tap. Interesting implementation of an idea.
I would guess that you're 'not allowed' to connect a pump up to your own plumbing if it's also on the grid, naughty naughty. Doing so in 'a grid down' by isolating at the meter [turn off] and running to say a garden tap I suppose might be a choice and would give you water using your normal plumbing on demand assuming you have the necessary water storage. You'd also have normal toilet facilities for some time even when water wasn't available elsewhere. If that storage was refilled by rainfall and the pump battery charged by solar, you'd have a complete ongoing system. Personally I think it's a brilliant idea and would add much to the morale and convenience to be able to use your normal taps.

Awww but Mr government, why is he allowed CCW/OCW and we are not Great idea, might order myself a pump now just to throw into my assorted projects pile

Only so much money and time. Looking on fleabay,you can get 18L/min pressure pumps for between $70-100

Awww but Mr government, why is he allowed CCW/OCW and we are not Great idea, might order myself a pump now just to throw into my assorted projects pile Ha, nope. I think I'll put together a small kit for this, I'll give it some time to peculate to think about it though looks simple; Criteria of kit ------------ - Collect rain via down pipe into storage - pump water from storage - Charge battery via solar - Use normal taps to do - Helps give redundancy to sanitary, particularly toilets Questions ------- Draw characteristics, aka how much power and water is used. 5L/day/person is a bare minimum and would like to understand rainfall rates at the time of the year so a daily ration can be allocated and translated into how many seconds a tap can run for instance and align with the number of times a toilet is used etc. Can look at water usage data on bills to see a maximum though my catchment is not nearly going to be close to that. Spreadsheets to be made Probable parts ------- - Small solar panel with enough wire to locate in sunny spot for charging. - charge regulator - battery - hose connections and length of hose [it's under pressure] - case to protect from elements. - pump

Shiney toilets can be gravity fed if need be Little bit of tinkering Although you still need to pump water to higher level When we worked on stations in outback west Aus we had 44 gallon drums on platforms that had fire underneath and then that water went into normal taps etc so we had full hot running water Would t work for dish washer rtc no pressure but the small electric pump that pumped the water from tanks to drums was enough to keep all the hot water we neeeded

Love it. Anyone found a suitable pump for this application?

There is another way for hot water although no pressure

To the point of just getting a bucket and poring it into the bowl, no need for water pressure at all. We've been living off those Sureflo and Flojet pumps for donkeys years, they work well. I would add an accumulator as well to reduce the cycling but it's not strictly necessary. The red tank under the Sureflo is a large accumulator, most people use something a lot smaller but if a job's worth doing it's worth over doing I've always said. I also made a small version of what SouthernPrepper1 has Seen here getting water from a creek, note the water meter so I know how much I got. As for using a garden tap to back flow water into your system, I doubt that will work as the washer in most taps is pushed open by the pressure in the normal direction, if the flow is in the other direction it will push closed. I would hack into your system and install a ball valve.

Thanks for the tips there Gray, will add a ball value and adapters so I can use it on a variety of size fittings.
That green box looks the part, any ideas on how long the battery would last/how many liters it pumps? I'm thinking if you're only using it a little it might the be the go, particularly if it's also getting a daily charge with solar etc.

Nice system you have there Rob, May I ask what size pumps you are using, I have a system that works ok on my camper trailer but it only runs a tap for drinking water, It is only small compared to what you have in your pictures, I would be interested in getting a bigger pump to use for my garden.

I'm thinking if you're only using it a little it might the be the go, particularly if it's also getting a daily charge with solar etc. No idea I'm afraid, I normally used it quite close to the car and in that case I connected the car's second battery in parallel with that small SLA (you can see the back of a DC connector inside the box on the right side). The car had a 45-litre tank and that's as much as we ever filled IIRC.

Paul We've used various Sureflos over the years, ranging from 9lpm to 13lpm I think, I don't recall the 9s seeming any different to the 13s though. They have been good for everything in the truck (including showers) and in various 4x4s. I just checked the one in that green box, it's 1.8gpm (6.8lpm), but I don't know how that compares to the ones running stuff in the truck as they are under the floor and too hard to get to, pretty sure I went for 13lpm there though.

thanks Rob, I will start looking on evil bay to see what I can fined, not that I need another project at the moment but if I find one at the right price well then I ill just have to get it. I will tell the wife it was on sale and I just had to get it. she believes me every time.

Gray, what size accumulator are you running there, and did it make any changes to the pressure, and if so, for how long? By that i mean, once the accumulator emptied and the pump started again, did the pressure drop?

IIRC it's 20 litres, bu tit's 18 years since I bought it.
The pressure does drop a little I think but it's not very noticable. It depends on where you set the pump's pressure switch trigger point and maybe what pressure you put into the accumulator. But overall I think it's just the pressure switch that determines the change, essentially the pressure cycles between the cut in and cut off points, the accumulator just lengthens the time between cycles.
