Feed the rainwater in toilets

[salsitawapa]

Bonjour,

I must point out here that any assembly allowing a physical connection between the different interior networks is henceforth prohibited.!

any assembly of the type double-valves, valves + non-return, anti-machine or anti-bazaar is no longer authorized, including even the backflow preventers themselves !! (which do not prevent a possible rise in bacteria although they avoid any "water return" ..)

the principle of disconnection "by total overflow with load break" , as applied to automated pumping stations (which all installers now install) approved to standard EN1717 ...

Can you give us a site which has it in photo with explanation STP? And where to buy it + price ??? Thank you

yes, but, once it has passed ....

I can see a tap in the garage that we connect with a garden hose to the other circuit, between 2 inspections

If it is that for the water of the toilets, the simplest is still to put a new small pipe which goes from the tank (or the pump) to the reserve of the flush of the toilets (garden hose 16 or 20 mm). The tanks of the toilets plan to be able to put a float system on the 2 sides and at home I put 2: when the rainwater tank is full, I close the water tap of the tank coming from the network, when there is no more water I open it. That's all !

well in fact, it is not a "device", or a "product" (material) that we buy ... but a "principle", a "system" of application ...

water must pour out falling" to have a "load break" or "air gap" (mini 5 cm) between the outlet of the city water supply pipe (make-up) and the maximum water level (overflow) in the make-up tank into which the pump will draw the city water if more rain water available ..
so as not to have physical contact between the city water supply pipe and rainwater or its circuit ...

yes, but, once it has passed ....

well .... everyone cheats if he wants and as he wants ....
but it's still a purely personal matter .. !!

That's all !

example which seems to me to be the simplest and the most relevant .... in this case where it only concerns WCs for indoor use ...

So like that, we get the charge break, right?

[Grelinette]

"Load failure" ...
kezako?

Re,

normally yes ....
but only for the WC ...

"Load failure" ...
kezako?

see on this page .., the second diagram (Set of protection) which gives you an idea (on this example for an evacuation) of what is "a load break with venting" ....

Re,

and also , an explanatory video of the operation of a "BA type backflow preventer", but which acts more as an "improved anti-return valve" and keeps physical contact ....
therefore does not correspond to the principle of "total disconnection by overflow" (with load break) which is now required ....

Said and why not make a separate circuit powered by a vacuum pump, like everyone else?

No return risk or drinking well water in this case!

You feed your toilets, your laundries and hop finished the comedy

Bonjour,

yes, of course, but only if there is certainty (with safety margin) never to be dry in rainwater for the uses reserved for it from the start ....
(which is rarely the case ..)

there is also (as I have already explained) the flexible hose system connected to a double supply, either rainwater or tap water ...
(which costs a lot less than doubling the circuits!)
