Dear, I need to install a cistern and - for practical reasons - I am thinking of doing it using a unified pipe system , where the same rising pipe (or pumping) is a at the same time the descent (or distribution).
I don't know if the correct name is "unified pipes", but I tell you with graphics below.
Currently, the system is as in the image:
PROBLEMS:
-The water no longer reaches the upper floors and for many hours of the day it does not reach the ground floor.
-Large part of the rising pipe is embedded.
MY IDEA:
Concerning that it is only an office building (without hot water network)
My big question is what will happen when the pump is running and a tap is opened simultaneously? [/B]
I think there would be no problem, only that the water will come out with more force from the tap and the elevated tank will take a little longer to fill. But I wanted to ask you any questions about your opinion.
THE MOST IMPORTANT THEME I BELIEVE is not to forget to install the [b] Check Valve (check), after the pump, so that the Water in the Elevated Tank does not return to the tank by gravity.
I want to do it this way so as not to delay installing another pipe, breaking walls, changing tiles, etc. (Aerial would be very unsightly).
It is also only cold water, there is no hot water network. They are offices and commercial premises.
There is a video on YouTube where this system of "unified rise and fall" applies but not with a pump and tank system but with direct use from the Public Network and elevated tank. (minute 04:36)
Thank you very much friends for reading and if you have any more comments.

Hello, it is not bad wave, they are 39 years of trade, I never saw an invention of these that succeeds, all that is solved by placing an outer pipe, besides going out much cheaper and always work. An anti-return that sticks to you and a problem appears that will also take time to discover. Cheers !
Thank you! As the Achilles heel decision of this is the non-return valve. I didn't know that those valves can get stuck. Thank you very much for highlighting that point.
Of course, the idea of all this posting is to avoid an external pipe and I was consulting with you. But seeing that this valve can fail, it seems to me I will do it with just an external pipe.
Hi. It is feasible to do what you mention but the issue would be the state and diameter of the pipe. As for the pumping pressure, as you say, when a tap is opened, the flow rate will be lowered a little. What if, you must make an automatic filling system between the tank and the elevated tank. Regards
Thank you!
The pipes of 1st and 2nd floor have a good diameter and are made of PVC. The ground floor are from HidroBronz. We will see.
Yes, it goes with an automatic system, but I forgot to not load the drawing.
I will try to contribute to your dilemma the following, if you connect a pump to the same pipeline, the pressure to reach the tank will overcome the resistance of the floats in the toilets and you would have lost, in addition to the losses of load in the pipe not designed to raise water There are many so you must put a high power pump and also it is necessary at least an inch or an inch and a half to get the tank with good flow.
