I found that . 26 € 50 for 4 13000 liters per cartridge, i.e. 52 m3 treatable for 26.50. 2 € lem3 .... Otherwise the cheapest in UV filtration that I found is 550 € ... What about the lifespan ???

the lifetime of a UV tube is the same as a standard fluorescent tube.
By looking well we can find this kind of tube for not too expensive (see Francelampe for example) because in supermarkets they sell you that at an indecent price.
In absolute terms you can make a UV sterilizer yourself, it is never more than a water circuit around a UV lamp
The problem is that the glass used must be transparent to UV (quartz glass I think) otherwise the system loses a large part of its efficiency (the silica glass absorbing a large part of UV-C)

Look at the side of aquarists, some must have a tip to make this kind of device.

Well ... if someone is interested ... Oddly since the level of the tank has dropped the smell has faded ...

Hello,
I also have this odor problem from the start, only when I do not draw water from the tank for 10 or 15 days. (Standing water)
Example: back from vacation, there is a smell for a few days, then it disappears.
I also noticed, that there is a micro accumulation of sediments at the bottom of the boiler, therefore, I will have to purge it from the bottom from time to time.
Ps My tank is 7000 liters.
So don't panic.

Try to put some metal copper as a pipe in the tank, because the copper blocks bacteria and mosses.
Copper is very effective against legionellosis and may be that the water which arrives is passed before in copper pipes which block proliferation for a few days ????????????????????? ???????????

Copper is effective on roofs (danger for zinc gutters).

The thing was already known in ancient Egypt.

a friend who recovers rainwater to water his flowers (very nb)
and who was tired of hanging watering cans around the house asked me to make a small pump with a small hose of 50 meters

I opted for a small booster pump made with a coffee machine pump and a boiler expansion vessel and a 6x8 rilsan hose
it grows to 4 bars and enough flow to water flowers
it can give ideas
Image


good evening, well I have already seen this type of pump in a coffee machine that we find in public places or in the big coffee machine in the canteens where we use ourselves I thought that the pump came from a espresso machine but this one goes up to 16 bars maxi and it is also smaller

I even found a link http://grimac.fr/moteurs-et-pompes/1455 ... rocon.html
the motor that goes with the pump

http://www.grimac.fr/moteurs-et-pompes/ ... 23050.html but hey I don’t know at what pressure it rises this kind of pump, according to boubka at 4 bars

I read that putting charcoal in a tank prevents the proliferation of mosses and algae.

I will try to put a good dose of charcoal (5 to 10 to XNUMX approximately) in a fabric bag and place it in a rainwater collection tank for watering. I'm just thinking of putting charcoal sold for barbecues.
What do you think ?

Otherwise, to make a large tank for collecting and storing rainwater, there is the trick of recovering a plastic septic tank (beware this is not food !!! just for watering). Some are up to 5 m3.
Image
At the moment, depending on the region, they are emptied and removed because connection to the mains drainage has become compulsory.
The companies that remove them get rid of it and I was able to recover it for free. A good blow of karcher and it is (almost) very clean.
