practical solutions are the best. dont say i am not helping you.

[Kikapu]

I am still waiting for the expert on gravity fed water to explain me why the hell water doesn't flow from my tank after it gets empty and I fill it up. It's a REAL CASE, i shake the pipe,kick it, nothing! It simply refuses to flow.
Here's the drawing. It puzzled me for a long time and ever since I don't let the tank go full empty. The reason is not rocket science though.It was just unexpected.

Lordo, gravity fed water expert where are you.Why water doesn't flow from the damn tank which 3m+ above ground???

It may be an obvious question but is the tank sealed tight after you fill it up? Air must be allowed to flow in to allow the water to flow out.

Not sealed tight. It has air holes inside the lid.
Notice the very first time I installed it it had absolutely no problem. The problem started AFTER it got empty and I refilled it. Concentrate on this and you will find the reason.
I was scratching my head cursing, and kicking the damn pipe for a long time...

NB.The gravity fed water expert lordo, obviously has no idea.

I think you need to prime the pipe to remove any air pockets that's in the pipe, to get rid of any back pressure, much like if hydraulic fluid that runs out of your car's brake line, and just by adding more brake fluid into the brake cylinder will not make your brakes work. The brake line needs to be bled first, to get rid of any air bubbles. Same when siphoning, one needs to suck out all the air out of the tube to create the flow, and once the flow starts, gravity force of the flow then takes over to maintain the flow of the fluid.

this is from the Turkish newspaper report linked above:

"Unless the problem is resolved, the planned official ceremony will be postponed and fresh water flowing to the TRNC will halt, sources added"

Remember what I had posted regarding the control over a vital resource such as water? This is the problem when others control your vital resources. The two desal plants would have been under the municipality control that the TCs want, not private companies, not people with "expertise". Now sit on it and rotate. Your water is in foreign hands.

GENERAL PRINCIPLE:Air in water knows only to go up. Doesn't want to turn right nor left nor go down.

My friend Kikapu with his usual common sense spotted the problem is the trapped air, and my "friend" B25 got the solution in one shot. Apologies for initially saying "nope" to your solution B25

When the tank gets empty then from A to C we have air and from C to end end of the pipe where the on/off valve is, we have water.
While we fill up the tank the existing air in part A to B escapes inside the tank.As soon as water runs down to the beginning of part B all it finds is trapped air. Upto that point the water has only the pressure corresponding to the elevation difference between point B and the top of the tank, about 0.08 bars. However the trapped air wants to go up and pushes upwards hence nullifies the little water pressure we have at that point. Hence no flow.I had the valve open for 2 whole days, no change it flowed drop by drop "damla-damla" as our gravity fed expert would say.

Herebelow B25's solution. All household water tanks have it.

where is shitface these days. there he was saying this was a pipe dream.

and what pipe dream it has turned out to be. come on show your face. its not that bad, we all knew you were full shit from the beginning.

they almost got the name of the album right. the invisible land.

Shitface will be back when you post a real vid of a real 1.5m pipe gushing real water on to the shore of Occupied Kyrenia, brother really Spasmeno

... and isn't it damning that the excuses for this Flop of the Century, for this failure of a projesi, have already started.

ang on a mo charlie hang on a mo. shitface and pyroplastics dustcloud ave been crapping all over this forum with yourself and a few other assholes not to exclude any charlies or the old cnut telling us it was not possible and it was a myth and the terggs were pulling a fast one. there is a need to explain their stupidity. staying away from the forum aint the answer.

The real life example of my water tank was to show you there are a million unpredictable problems that may arise.
One of the known problems though is that of air getting trapped or produced by the water itself (it evaporates molecularly at high pressures).
The Turks did not present ANY method of de-aerating the system. There are no de-aerators in the market working at depths of 250m. Even if they just keep it a secret and they place floating de-aerators at sea level connected to the system 250m below, if one of the connections brakes how are they going to fix it?? The depth itself forbids maintenance or repairs.

It is you who is stupid enough to believe this thing is ever going to materialize, and more stupid if you believe it's going to last for more than a week or so if it ever materializes.
Just digest it, the Turks are going to bring you water with ships and fill the dam there. The dam itself is smaller than Kalopanayiotis dam which is one of the Republic's smallest ones anyway.

you are so clever
your brain is so sharp
you be careful now you dont cut yourself you hear. stupid boy.

there are two dams. the one in trnc is small. its size is immaterial, it will fill up constantly. what matters is the dam in terggy.
you are just too clever for terggs.

you claimed this was technically not possible. you have been shown to be as thick as shitface. you still insist on posting your stupidity.

carry on bubble and squeek.

can we assume that you have personal experience on the sucking issue. you made pyprobolla happy.
